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.

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? Do I want to allow them to place me on a ventilator?"

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 is when a person has decided they do 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 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 CPR 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 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 Rescucitate. 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.

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 with ALS (Lou Gehrig's Disease) or multi-system atrophy, which is a disease my grandma suffered from at the end of her life, and is a disease like ALS in that the person loses control of his muscles and basically becomes a brain without a body.

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, and I totally understood those wishes. However, there is 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.

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. However, 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 d0 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 looks 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; 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 know 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 explains.

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. "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, and then in 24 hours 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, before continueing. "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 solemly states, "However, if he doesn't go on a vent now, there is very little chance he will survive this."

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.

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.

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.

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 should your heart stop, or whether or not you want to go on a ventilator should you stop breathing (and many times those two come together in the same package), 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 stress in the end.

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.
