One thing; did you mean to say "Consider V = ventilation and Q = perfusion" rather than "P = perfusion?" (In a former career, I proofread corporat documents. Can't kick the OCD!

Has there been any updates on this topic? I was actually doing more research to answer a question on an assignment about hypoxic drive and came across this. It is interesting in to see instructors within the medical field, even RT's who sound so confident in something, yet there are many who disagree and outright say it's a myth.Anonymoushttps://www.blogger.com/profile/06588742746901957506noreply@blogger.comtag:blogger.com,1999:blog-7423880838207203660.post-88895927372946358652014-12-14T19:15:30.910-05:002014-12-14T19:15:30.910-05:00your should write textbooks..

I am a nursing student taking patho and your have just explained everything so well that I cant believe my final is tomorrow and I just found this. Thank you so much. I will pass this on to my instructors. In the medical surgical nursing text they do support the use of 2L/min oxygen for COPD patients presenting with respiratory distress. They also recommend encouraging pursed lip breathing, abdominal breathing, and incentive spirometry.Katianoreply@blogger.comtag:blogger.com,1999:blog-7423880838207203660.post-48102937916146332632013-04-15T11:16:01.024-04:002013-04-15T11:16:01.024-04:00If a physician tells you to turn down the O2, and ...If a physician tells you to turn down the O2, and you know that hypoxia kills, how can you NOT refuse to follow orders if you are acting in the patient's best interest? Following physician orders, especially when you know that following said orders could result in a poor patient outcome, has NEVER been held up in a court of law. Is this a case of making sure your malpractice premiums are paid up to date?<br /><br />TMB, BS, RRTAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7423880838207203660.post-77519721813501046382012-12-14T08:17:54.692-05:002012-12-14T08:17:54.692-05:00Thanks, Steve.

This causes an increase in CO2 in the blood, or an increased PaCO2."<br /><br />so I presume that applies to all people despite if they are CO2 retainers.<br /><br />"Most people would simply increase their respiratory rate and blow off this CO2."<br /><br />with this information may I conclude that O2 supplement cause people to breathe faster in order to get rid of the CO2 accumulated in the blood? But O2 therapy is known as to reduce the workload of breathing.
