NIV proven useful for COPD, CHF, yet failure rates still high

Noninvasive ventilation (NIV), either in the form of Noninvasive Positive Pressure Ventilation (NPPV) or Continuous Positive Airway Pressure (CPAP), has been used in the critical care setting since the end of the 1980s, and is now commonly used in both Europe and the United States for the treatment of COPD exacerbatons and heart failure.

Studies also show that NIV may significantly decrease work of breathing, either by improving minute ventilation (COPD) or by decreasing venous return to the heart (CHF), and thereby reducing the need for intubation to 15% (although it is as high as 38% in patients with chronic respiratory disease).

However, despite it being so commonly used, and despite all the advancements in technology and equipment that have improved patient comfort, studies continue to show that anywhere from 20-30% of patients fail.  Of the patients who fail, 30-40% require intubation and mechanical ventilation.

A good indication of failure, or a good predictor of who will fail, is hypercapnia after initiation of NIV.

Contou et al, however, concluded that experienced respiratory therapists may make adjustments at the patient interface (mask) or changes in settings that make the experience more comfortable and more effective, thus resulting in a reduction in NIV failure rates to under 15%, thereby reducing mortality rates to 5%.

Contou et al also showed that, by using an NIV protocol and having the patient closely monitored in by experienced personnel, including a nurse and respiratory therapist, 48% of patients who were semi-comatose responded well to NIV therapy without the need for intubation.

The study shows that trialing patients on NIV in an experienced unit where the patient was closely monitored, even those who would otherwise have been intubated, has proven to be effective, thus further reducing the need for intubation.

Likewise, the researchers reported, "it has been shown that NIV failure was not associated with an increased mortality rate in hypercapnic patients; thus, delayed intubation in some patients likely did not worsen their outcome."

The bottom line here is that NIV protocols that allow the nurse and respiratory therapist to closely monitor and adjust the settings on the NIV "might reduce the intubation rate.

Why are tracheostomies better than endotracheal intubation?

The general recommendation for the management of patients who require endotracheal intubation and mechanical ventilation is to extubate as soon as possible.  However, in the event a ventilator is required long term, the experts recommend the patient be trached after seven days.  

Why is this?  What are some advantages of tracheostomy over intubation? 

What follows are the essential advantages of tracheostomy over intubation:

• More comfortable than an ETT
• Makes it easier to wean a patient off a ventilator
• Reduces need for sedation because it's not as uncomfortable as an ETT
• Reduces risk of trauma to airway as might be causes by an ETT
• Reduces airway resistance to make breathing easier for patients
• Allows patient to breathe when upper airway is swollen or collapses (such as with paralysis caused by neuromuscular disorders or epiglotitis)
• Makes it easier to suction the patient with thick, or copious secretions
• A patient can talk with special trachs

Alternative therapies for status asthmaticus

So you have a really bad asthmatic in the emergency room, and you already have him on a continuous bronchodilator breathing treatment, and the nurse has already given intravenous epinephrine and solumedrol.

Now you, the RN and the doctor are willing to grasp at straws to prevent that person from needing to be intubated. What are some choices you might be able to recommend to the ER physician?

A book called Fatal Asthma and CMAJ list some of the most common "alternative therapies."

1. CPAP: This can be started to help the patient overcome his increased work of breathing. Adding CPAP is also a great technique of overcoming instinsic PEEP that causes hyperinflation. The problem with this is that asthmatics already feel as though they are suffocating, and this might make matters worse.

However, with good equipment, good coaching, and a doctor willing to apply to the patient some sedatives, this might be worth a shot if you have a compliant patient.

2. BiPAP: All the principles of CPAP apply here, except this also applies pressure with inspiraton to help the patient take in a deeper breath, thus allowing the patient to blow off some CO2. This may be of particular use if you suspect impending respiratory failure associated with a rising CO2.

I have seen BiPAP work on at least five asthmatics in the past couple years. Usually if a patient is bad enough to require noninvasive ventilation, we skip CPAP and go right to BiPAP.

3. Heliox: This is a helium/ oxygen mixture that consists of 80% helium and 20% oxygen. With the exception of hydrogen, helium is the lowest density of gas. And, according to medscape.com, since asthma is a disease associated with narrowed passages that result in turbulent flow and increased airway resistance, heliox can help create a more laminar flow, and thus decrease the work of breathing

According to studies, some patients benefit from this and others do not. So, while this is used in some hospitals, the jury is still out on whether it is a cost worthy investment for hospitals.

So now you have a patient in status asthamticus intubated in your emergency room. You have tried all the conventional therapies, and you once again are grasping at straws. What are some options?

4. Bronchiolar lavage: Also known as lung lavage. This is done with a fiberoptic bronchoscope and washing the bronchioles out with normal saline with the intent of clearing the lungs of mucus plugs. This is still not commonly done in a crisis, but remains an option.

5. Anesthetics: These are used to relax airway smooth muscles. According to Fatal Asthma, "Rapid, dramatic improvement is reported, leading to more effective ventilation and in some cases early extubation."

Ketamine is a smooth muscle relaxant and antihistamine, and is given intravenously. Of course this medicine is a known hallucinogenic, and it is a sedative. Many doctors prefer to wait until a patient is intubated to use it, and follow it up with a paralytic, as you can read here.

Isoflurane is an anaesthetic and bronchodilator that has been proven to be efficacious in ventilated patients in status asthmaticus. According to this study, " Isoflurane improves arterial pH and reduces partial pressure of arterial carbon dioxide in mechanically ventilated children with life-threatening status asthmaticus who are not responsive to conventional management."

6. Permissive Hypercapnia: This is something I'd wish doctors where I worked would consider more often. We had an asthmatic a few years back who was admitted to CCU, and the doctor ordered a tidal volume of 750. Since I was bagging the patient, and her lungs were stiff, like ventilating a brick. When I finally got her hooked up to the vent the highest tidal volume I could get was 150. The doctor was irate. But I was right. He finally admitted as much.

So, the point with permissive hypercapnia is that you allow a high CO2 and low pH at the expense of low pressures and a lower tidal volume and an appropriate respiratory rate to allow time for the patient to fully exhale to prevent air trapping. You do this while continuously trying to get the patient's airways to open up. In this patient's case, it took two days for this to happen.

As the author's of Fatal Asthma state, "Prolonged severe hypoxemia can cause devastating neurological injury and death, prolonged hypercapnia per se is thought to have no long-term adverse consequences. Use of permissive hypercapnia has become standard practice in many intensive care units and in general has rendered unnecessary other 'heroic' measures in the critically ill asthmatic patient."

Well, those are some of the options available to today's physicians for the treatment of status asthmaticus unresponsive to conventional therapies. Where I work we've used BiPAP and Bronchiolar lavage, although rarely.

I've known about heliox and permissive hypercapnia, but the anaesthetics used to treat status asthmaticus is something new to me. If these medicines were ever used at my facility I'm unaware of it.

If any of my readers know of any other alternative therapies for asthma please share them in the comments below.

ETT holders work wonders

The worse codes are those that take place in unexpected places -- like CT.

The call was overhead: "Code Blue to CT!"

I rushed to CT to find a patient already intubated. The anesthesiologist was standing at the head of the bed holding an unsecured ETT.

As soon as he saw me he gave me that job, and now I was standing there at an awkward angle with someone breathing down my back in the closed in room holding the ETT in place.

The funny thing I had no idea where this patient came from. Then I realized it was not a patient from ER (of course not, I would have known), it was a surgical patient the doctor decided needed a CT.

The ETT, I noticed, was secured only with tape. Something ACLS does not recommend when you are transporting a patient. Something common sense does not recommend when you are transporting a patient.

Suddenly I hear the following: "On a count of three: one..."

"Wait!" I say

"...two..."

"Wait!"

"...three... heave!"

"Shit!" the patient slid down the table and my feet and my hands stayed firm in the position they were in holding the ETT....

Only now the ETT was no longer in the patient.

The anesthesiologist said nothing. He easily and calmly reintubated. And, at which time, I secured the airway with a good solid and firm bite block or ETT holder or whatever you want to call it.

When I was finished I admired my work. "See doc," I said, tugging on the tube to indicate it was secure, "This is how you secure an ETT!"

He smiled.

The old technique may have worked fine in the day, but now that we have access to better research and better equipment, we might as well use it.

No Vent, DNR, or full code: what's your choice?

The decision of whether or not you want to be placed on a ventilator, or whether or not you want to make a decision for your loved one, is one of the most difficult decisions one can make. In fact, this is the basis of some very deep ethical discussions, and one of which may never be answered by society, only by the person who has to actually make that decision.

First let us note here that a majority of patients who go on a ventilator do so only for temporary purposes. If you have surgery, if you have severe asthma, pneumonia, or failing heart, you may need to be placed on a ventilator short term, just to get over the hump, per se. If a person is involved in a trauma, or if CPR is performed, then a person may be intubated and placed on a ventilator.

Those are easy decisions, especially when we are in emergent situations and are trying to save a life. However, there are also times when the decision to intubate or not to intubate can be complicated as complicated can get, and very stressful, and often disappointing if not discouraging.

In some cases you can plan ahead and write in your advanced directives that you do not want to be placed on a vent.  However, sometimes I have seen this declaration over-ruled at the point of impact when a person is in the emergency room and the person has to decide, "Do I want to risk dying now, or do I want to let these good people here in the emergency room help me breathe by placing a tube into my airway and assisting me with my breathing? Do I want to do that?"  More than likely, it will be, "Do I want mom or dad or grandma to die?"

Here I will provide some examples for you. All of these come from real life examples as I have actually seen them in my eleven years as a registered respiratory therapist.

One of the most frustrating examples to me was when a person decided they did not want to be placed on life support because, "I don't want to spend the rest of my life on one of those things," or "because I don't want to become a vegetable." In thinking this way, many people choose the following in their advanced directives: Full Code, Do Not Vent, or Do Not Intubate.

I have to cringe when I see that. I cannot believe any lawyer or doctor -- or advisor -- would recommend that option, because when a person's heart stops, and we have to do CPR on the patient, we also have to pump in quite a bit of medicine, and 99.9% of the time the patient does not survive a code breathing on his own: he has to be intubated and placed on a ventilator. Thus, if we do CPR, we have to put you on a vent -- there is no other option.

What might confuse people is what you see in the movies. There was one episode of "Walker, Texas Ranger," where Chuck Norris's character was having chest compressions performed on him, and his friend who broke his arm was watching on. Then Chuck woke up, the ambulance arrived, and the person who was taken away on the ambulance was not Chuck, but Chuck's friend with the broken arm.

It does not work this way in real life. The majority of the time when CPR is done on a person, that person buys himself a ventilator. That is, unless you are a DNR. In short, DNR means Do Not Resuscitate. That means if your heart stops we will not try to restart it. And, if you stop breathing, we will not place you on a ventilator. We will let nature take its course.

However, if the people working on you don't know you are a DNR, you will end up on a vent regardless. Not only is that the ethical thing to do, it's the law. If you're going to err, you err on the side of life.

However, I do think the decision not to become a vegetable on a vent is a valid issue for most people. Yet, one also has to consider the definition of a vegetable. Are you a vegetable when you have no body, but your brain is fully functional (as would be the case Lou Gehrig's Disease).  Or are you considered a vegetable when your brain if officially declared dead but your body continues to life?

Some people value life so much that they would want to live so long as they have control of their brain. That was my grandmas wishes when she was diagnosed with multi system atrophy, a disease similar to Lou Gehrig's Disease.  As a pro-life advocate, I totally supported her decision.

However, there was also the issue of depression and humiliation as you are fully aware that you have a tube up every orifice, and some strange person wiping you every time you have a bowel movement. Not only that, but you have to have someone assist you every time you move anywhere. Basically, you are a mind without a body. Do you want to live like that? Do you value life that much? Some people do. And we medical workers respect that.

Then you have the people who have Alzheimer's. These people will have fully functioning bodies but no mind. No mind no matter, no matter no mind. I would imagine that this might be the best way to end your life on a ventilator, if one had to choose between the two.

If I were an elderly person diagnosed with Alzheimer's, I would simply make a wish to be a DNR just so that I wouldn't become a ward of the state, a useless blob of skin on a bed taking up space and absorbing taxpayers money.

However, that would be my decision. I have to respect the wishes of others who think otherwise. Thus, life is very precious no matter how fragile, and each individual has to decide for himself. Grandma should be allowed to  choose for herself how she wants to die. This is why it is so important for physicians to be honest with their patients and talk to them about end of life options.

Then, let us consider the COPD patient who decides that he does not want to be placed on a ventilator. He is not necessarily end stage, but he is to the point that he cannot go without using his oxygen. However, he has a quality life to the extent that he is not one of those people who simply sits around and feels sorry for himself. He loves life. He loves living.  Yet he was also scared by the prospect that he might be placed on a ventilator and have to stay on it the rest of his life. So he makes the decision one day that he will make himself a dd not vent patient.

Then one day he is having trouble breathing. His wife drives him to the hospital and by the time he arrives there he is severely short-of-breath; his work of breathing is labored. The doctor looked the patient straight in the eyes and asked the question no one wants to ever hear: "If something happens to you, do you want to be placed on a ventilator?"

Of course now the patient is not in the planning stages. He is actually miserable, gasping for every breath. His oxygen levels are falling. His CO2 levels are rising. He is pooping out. He has a feeling of impending doom. He, however, does not want to die; he is not quite ready.

Then again, he does not want to go on one of those things either; he does not want to be intubated.

So, he asks the naive question that is really not so naive because the only people who truly knew the answer were standing in the bright room around him. Of course there were other COPD patients who knew the answer, but they were not in the room. His life, his destiny, was in the hands of the fine medical workers in the room.

"So," he says, huffing and puffing, barely able to get the words out, "How long would I have to be intubated for?"

"Well, the goal would be a day or two, but we really can't guarantee," the doctor explained. Of course she doesn't want to give false hope, but she also doesn't want the patient to simply give up hope at the same time. This is the ironic twist that we often face in the emergency room. She continued: "The goal is basically to rest your lungs and allow them a chance to heal. That's the goal. I can't guarantee anything, but that's the goal."

I stand there thinking, as I am getting my intubation equipment ready just in case the patient makes the decision, that the doctor made a good presentation. In fact, I couldn't have worded it better myself. The key words there were help you get over the hump and I can't guarantee anything.

By these short phrases the doctor threw the ball completely in the patient's corner. And, if the patient were to pass out, into the wife's corner. And if the wife were not there, the medical staff would have no choice but to make the patient a full code and do everything for the patient, unless they were 100% positive the patient was a DNR.

Another case I've seen is the elderly man with a chronically failing heart come into the hospital in respiratory failure secondary to the failing heart. The patient is non-responsive, and he is also not a declared DNR. The wife now is forced to make the decision of whether or not to allow nature to take its course, or to allow the medical staff to intubate her husband and place him on a vent.

"What should I do?" the patient's wife asks the Doctor.

"Well," the doctor says, "I know this is a difficult decision. Since you are in a very stressful situation right now and you want to make sure you don't make the wrong decision, perhaps it would be best to let us intubate your dad, and you can see how things progress, allowing yourself some time to spend with your family and to think. Then, in 24 hours or so, you can see how things are going with your dad. Either way, I can't make any promises. It's your decision."

The doctor pauses, allowing the patient time to think.  He then says, "Technically speaking, the goal of going on a vent is short term therapy to allow your husband's heart and lungs to rest. If things work out, he might come off in a day or two. However, I can't honestly say those odds are very likely right now. But, if things don't work out, he very well could be dependent, that's always a possibility. But if it comes to that, you can make a decision to terminate the vent if you wish."

After another pause, the doctor solemnly states, "However, if he doesn't go on a vent now, there is very little chance he will survive this."

Yes!  That was so true. The doctor was very honest with the patient.  He did was was necessary.

In this case, the wife decided to place her husband on the vent and the patient came off two days later with full mental capacity. Of course he was limited in what he could do, and had to go home with oxygen. And while his heart remained severely fragile, he was able to spend another two years with his family.

Thus going on a vent to get over the hump bought this man two years to say good-bye to those he loved, and allowed those he loved to say good-bye to him.

I talked to the wife a year after he died, she told me she was very pleased with her decision to place her husband on the vent. She said her dad was also very pleased.

One time we had a lady on a ventilator with ARDS, and as she was on the vent for the fourth week. It was becoming evident that she wasn't going to make it. The patient had already been given a slim 10-20% chance of surviving by the doctor.

But the family stood firm with their hope, and prayed the patient would not only come off the vent but have some quality of life thereafter. Even the family was starting to give up hope after a while, though. Then one day, as though by some miracle, the patient woke up and was eventually discharged.

I know that's a rare instance, but patients with grim chances of survival can survive. And while it might be fine to say, "I've seen people like this survive before," you still don't want to give a family member false hope.

Likewise, I have seen many cases similar to my above examples go in different directions. In the medical field, you just never know what's going to happen. And, when you are making end of life decisions, you never know what the right answer is.

There are times, though, where I would definitely recommend a DNR status. These would be elderly people over 90, and any person who has a terminal end stage illness. If you have an 80 year old lady dying of cancer, it would be kind of foolish to place that person on a vent, when all the vent would do is delay the inevitable, and cost the family insurance and taxpayers thousands of dollars in the process. I'm not saying that money is more valuable than life, I'm not saying that at all.  What I'm saying is that sometimes it's just noble to let nature take its course.

Yet, I see these people going on ventilators all the time. In many cases it becomes quite frustrating to see these people on the vent for weeks on end. And, this can quite possibly be one of the most frustrating parts of the medical field. Sometimes I even feel sorry for these people, especially when it appears to me they are trying to die, and their family members keep pushing for them to live.

Recently I placed a cerebral palsy patient on a ventilator. He is off now and back at home in the care of his family. The quality of life for this person was already pretty low, but the family loved this young man and truly valued the sanctity of life. We had to respect those wishes, and we took care of him as we would any other patient.

So, if you are wondering whether or not you want to be a full code or DNR, or whether or not you want to go on a ventilator should your body start to fail you, you should take some time to consider the what ifs.
It might be a difficult thing to stop and think about, but it could save you and/or your family members a ton of grief and stress.  It would help you and your family prepare for the end.  It would help you die with grace and dignity.  It would let you decide how you want to die.

As you can see, this is not an easy subject matter for anyone, including us in the medical field. And this has been and will continue to be an important ethical discussion for years to come, especially as we live in a world where we have the means to prolong life.

What's it like to be intubated?

As I was looking at my blog statistics, and checking the recent keyword activity that landed someone on my site, I noticed one person had typed in the query, "What's it like to be intubated."

I remember waking up from a surgery once, and this person pulling something out of my mouth. I had no idea until I went to RT school what had actually transpired at that moment: I was being extubated.

So because I was medicated, I had no memory of being intubated, and had no memory of my time on the vent during the surgery. Thankfully, I must add, I have no memory.

Fortunately, I think that is the case for most people who are intubated. I think that we keep them sedated enough that they do not remember much. However, on occasion, we do have to intubate people under emergency situations where there is no time to medicate the person, and usually that person gags and groans during the process. There is no doubting the this is not a pleasant procedure to have done.

Which is why Succiconine is such a great drug, because it paralyzes a person just long enough to get the job done. And then, while the patient is serving time with a ventilator doing all the breathing or assisting with it, a patient is sedated enough with some good meds to allow the person to rest comfortably. And, while the patient is often awake, the meds are good at causing amnesia.

Lots of times I have to communicate with a person on a vent. Of course they can't talk, but you get pretty accustomed to lip reading after a while. Then, a few days after the patient is over the hump and is extubated, you ask them if they remember being on the vent, and they will tell you they have no memory of it. That's not always the case, but most of the time it is.

Occasionally, a patient remembers everything. Some patients are awake, alert and orientated the entire time they are on a vent. It's these people where you can learn the most from of what it's really like to be intubated.

It doesn't always suck either. I remember this one chronic end-stage COPD patient who was extremely short-of-breath. She told me she felt like she was suffocating. The next time I saw her she was on a vent, and she looked at me with eyes of joy. She smiled. She took in a deep comfortable breath. That vent was her savior.

That patient did not want to get off that vent.

I like to explain to my vent patients, if they are at all comprehensive, that they have not been placed on a ventilator permanently, it's just short term until their lungs get better. It's more or less to allow their bodies time to get over the hump. That's the case most of the time. And, usually, the person is off the vent in a day or two.

While I can honestly say that I have experienced much of the things I do for patients on a daily basis, I have never been on a vent; and I have never been suctioned.

One of my co-workers and good friends and fellow asthmatic was placed on a vent once, and she said she remembers the whole thing. She remembers being awake and alert and looking out the window and seeing a Burger King, which sucked because she was starving. And, she said, that wasn't even the worse part. The worse part was getting suctioned. She said there is absolutely nothing worse than that.

That in mind, a fellow blogger who used to be an RT, and who is unfortunately a victim of severe persistent asthma, was placed on a ventilator recently. I thought his story was very inspiring, and I would like to link you to his blog: The Bay City Walker.

Monday's class: My response to your queries

Before I went on vacation I wrote a post responding to ten Google and Yahoo searches that linked someone to my site.

The reason I did this is because I know that 62 percent of those who click on my site stay here for less than five seconds and, in many cases, if they'd have just hung around a bit in the RT Cave they would have found the answer they were looking for.

So, with that in mind, here are my honest and not politically correct responses to all your queries. While some queries are so goofy they may lead to a facetious response by me, I will be completely serious when the question is a respectable one. I promise.

1. Respiratory therapy inserting catheters: God, I hope it never comes to that.
   
2. I hate respiratory: Why is it that this keeps coming up? I wonder how much time this person spent on my blog.
   
3. Signs a person might need to use an inhaler: You can do so by using a peek flow meter or by knowing the signs of an impending asthma attack. Another great place to find information about asthma is asthma mom, and National Jewish Medical and Research Center. The later hospital and a research center that specializes in pulmonary diseases. I know three people who spent time their for their asthma. It's an excellent place.
   
4. How to know when an asthma attack is occurring: See question #3.
   
5. What is it like being a respiratory therapist?: The best way to find the answer to this question is to check out what the RT bloggers have to say. It's a great job where you get to meet many wonderful people in need of help with their breathing. Some will need a simple breathing treatment, and others more intense therapy. The greatest parts of being an RT, in my opinion, is being part of a great team. We work together with Drs and RNs to the benefit of the patient. As with any job where you work with people, it can be very challenging at times -- yet rewarding too. This could be an idea for a future post. Stay tuned.
   
6. I'm sick with a cold in my chest bronchospasms: Sounds like you should go see your physician, or get one if you don't have one.
   
7. When to intubate: Here is a good link to check out. Cardiopulmonary arrest is an obvious indication for intubation. And during surgery patients are often intubated to keep them alive during the operation. Other times it's mostly a judgemental call made by the doctor and the care team, which includes us RTs. Here are some other indications: Ventilatory and Oxygen failure that might occur with asthma, COPD or pneumonia; to protect the airway of a comatose patient or patient who has lost his gag reflex; signs of impending failure where the airway will need to be secure, such as a trauma or burn patient.
   
8. Holter wheeze: You lost me.
   
9. What kinds of potassium does nursing homes give patients: I have no clue why this query was linked to my sight. I would have to refer you to one of my fellow RN medblogs for this. Check out the links to the right.
   
10. Can a peak flow meter be used for anything else: They are typically beneficial and helpful for helping asthma patients. Other than that, I suppose you could experiment. You could use it as a cool children's toy. You could have a competition during the last day of school to see who can blow the highest number. The winner gets a lolly pop.

That concluses this session.

Your Respiratory Therapy Search Engine Queries: Here are the responses from the RT Cave

I don't really spend a lot of time checking my stat counter, but about once a week I check it out for fun just to see who's been clicking on my blog. One of my favorite things to do while I'm there is click on "Recent Keyword Activity."

This is where my stat counter records what was typed into a search engine, such as Google or Yahoo, that led someone to clicking on my website. A few of the searches have nothing to do with respiratory, such as "Scratchy Neck," but the majority are respiratory related.

As I glance through the list, I wonder if that person had his question or concern answered. And, I think, they should just email me and I'd give them a legitimate reply, or at least I could tell them I don't know.

The reason I think this way is that some of these questions could only possibly be answered by an RT. So, with that in mind, I have listed some of the "recent keyword activity," and my humble responses.

1. "blowing into computer for respiratory": Um, I have no clue.


2. "Itchy neck pain": Um, how did that cause Google to link you to me.


3. "Duoneb pediatrics": Some studies show it works well in ER. Other than that I'd recommend just Albuteral. Personally, though, I don't see what it would hurt.


4. "Doctor doesn't believe in Peek flow meters: The doctor is a fool to disregard the benefits of a peek flow meter. It's a great tool to use in asthmatics to measure the effect of a breathing treatment, and to be an adequate tool to determine when to use a rescue inhaler, go to the doctor, or come here to the ER.


5. "Persistent croup": You can try the shower. You can taking the child outside in the cool air because many times it goes away on the way to the hospital. But don't be afraid to come in and get checked out. That's why we are here.


6. "Will Ventolin harm you if taken unprescribed": NO. However, I would not recommend it. If you have a need for Ventolin, you should go see your doctor.


7. "Does Albuterol Help Crackles?": No. The medicine particle size is too large to even get down in to the colapsed alveoli, and even if it did it wouldn't be able to re inflate it. But this is a great question, because often doctors prescribe Albuterol for this.


8. "Needle shot stings": Yes.


9. "How to write BiPap orders": With a pen in the doctors order section. It works best if you write the doctor's name followed by your signature. Plus I'd write "RT to set up BiPap to patient tolerance." Seriously, every patient is different, and every patient tolerates BiPap differently. That's how we write the order where I work.


10. "House filled with smoke from fireplace fever coughing": I would recommend not having the fire in the fireplace if it causes you to have trouble breathing due to it. It may cause you to cough, but it will not cause the fever. However, if you do have a respiratory illness, it may exacerbate your problem. Also note that it is not uncommon for smoke to bother people with respiratory illnesses.


11. "Respiratory therapy one treatment at a time": I would recommend it, but sometimes you will have no choice. If your patient takes nebs at home, or if the nebs are not indicated, then you should be okay doing more than one treatment at a time, just make sure you are only one or two rooms away. This is where it really comes in handy to know your patient. However, if you are new at this, or not sure, then you should definitely do one at a time.


12. "I hate respiratory therapists": What's your point.


13. "Breathing treaments for pneumonia": Same as for the question on atelectasis above: Albuterol does not get down to the alveoli. Besides, Albuterol relaxes bronchiolar muscles, and there are no bronchiolar muscles in the alveoli anyway. However, if the pneumonia causes bronchospasm, the treatment might work. Usually the first treatment in ER does the trick. If I were a doctor, I'd order Albuterol Q4 prn for these patients so we can give a treatment if indicated.


14. "Coughing spasms albuterol": If it's caused by bronchospasm then Albuterol is a good idea, othersise what's the point. Albuterol will not cause someone to stop coughing if it is not caused by bronchospasm. Personally, I'd try one and see what happens. It's a safe medicine.


15. "COPD on BiPAP": It works. And if it keeps them off the vent, you'll be happy and so will the patient. I've kept many patients off the vent by using a BiPaP. The big problem here is patient compliance. You will have to do a good job of explaining and be very patient with the patient.
    
16. "How long are patients intubated for": Depends on how long it takes them to recover. Depends on how sick they are. Many times, with the new microprocessor ventilators, it takes only one or two days. But every patient is different. If you are the family of someone currently on a vent, you should talk to the RT for an explanation.


17. "Do you give breathing treatment for cough congestion?": Yes, many doctors do. But Albuterol is technically speaking indicated for bronchospasm only.


18. "Where should one live with asthma": While there was once an advantage to living in dry areas like Arizona, research shows that this is no longer a benefit due to air polution.


19. "Why do people need to be intubated": I like to tell people that they, or family member, need to be intubated to get over the hump when they are really having trouble breathing. It allows their lungs to rest. Unlike in the movies, it is also indicated when someone goes into cardiac arrest. It is also done during certain surgeries, if someone is comatose to prevent aspiration, bronchoscopy, or you can check Wikipedia for more information.


20. "Tips for being a great respiratory therapist: Be patient. Don't be afraid to let other people take credit for your ideas. Do your homework. Most important, have fun with your patients and enjoy your job.

Well, I could go on, but I figure I had best stop at 20. There were many that I chose not to list here just because I saw via the stat counter that the person was linked to one of my articles where I know they would have found the answer if they read it.

Perhaps I'll make this a regular feature on this blog.
