Your stirring a bag of worms there !
I think the general, yet not fully accepted, consensus
Is that on a clear acute resp. distress :
- You put your Pt on 100% O2
And re-evaluate (Monitor for Bradypnea .. remove O2 temporarily & assess
response)
100% O2 for 20-30 min should not affect these Pts
Time enough to get the Pt to hosp or evaluated by higher qualified Med
personnel.
- If you have an O2 Saturometer try to keep them at 92-96%
- Follow you Medical direction guidelines... at whatever stage of
enlightenment that they may be
The Oxygen resp. drive theory has been both questioned and/or not
applicable to all COPDers
- Many of the COPDers that crash on 100% O2 are also considered at the end
point of there respiratory distress
- A weaker explanation is that once you raise their PO2 their cathecolamine
high wanes & they crash
- Yet, plenty of instance reported of COPDers that became bradypneic on
100% O2 & that did better when the FIO2 was reduced temporarily & did fine
on an ulterior lower % of O2
So there you have it
No real clear answer.

PS
Geography seem to be as an important element as theory here ! ?
Once these Pt crash & have to be intubated... they are extremely hard to
get off the ventilator
