Alan,
I’m taking some undergrad Physiology classes for fun. We’ve discussed this a little bit in class and I had the same question. The response I got was that there
is still enough oxygen bound to hemoglobin to last a few minutes as long as its circulated.
If cellular respiration is dependent on the partial pressure difference between PO2 and PCO2, then would the O2 still bound to hemoglobin be able to diffuse
to the brain? It seems like there would be minimal (or no) added O2 to the system through mechanical ventilation from the compressions.
It sounds like even if someone is conscious you are supposed to do these compressions, but I thought compressions should only be done when there is no pulse.
Thanks,

Doug,
Good to send that around.
Anyone can learn to do this, and like eye/skin chemical decon, anything is better than nothing.
When this first came out, I was a volunteer teaching CPR with the American Red Cross and I went to my co-instructor and showed it to her, and she was absolutely appalled.
We were, of course, both well-trained and certified this, that and the other thing in the medical/first aid fields.
As a Board Certified Emergency Physician and Advanced Cardiac Life Support CertifiedProvider and Instructor for aI remain unconvinced that circulating deoxygenated blood really does anything, but since probably anyone can learn this, maybe it wouldn't hurt.

This is a new, simple CPR technique that everyone should learn.

This short video illustrates the best demonstration and gives the simplest explanation of exactly what to do if someone near you
collapses and is presumably having a heart attack.
