How much pressure should you apply for CPR (quantitative ex: 5 psi)?
Answers:
In adults it is enough to compress the chest 2 inches.
It would depend on the individual patient. Obese patients require more pressure than cadaverous ones. It varies.
I am curious as to how one would measure the PSI in the field? You would obligation to know how many square inches of contact you have with your foot.
The other issue would be the strength of the rib cage. The smaller, more flexible infant ribcage would achieve the desired results with a much smaller PSI than the ribcage of an developed with heavily calcified bones. How would you determine the forced needed in the field?
As a CPR instructor myself, I can read between the lines your curiosity, but I cannot see this as being helpful information. It would just be another number that really does not penny-pinching anything and we cannot afford to give the students anything that would possibly confuse them in their tasks.
The compression ranges give the impression of being to me to be a perfectly useful tool without describing people such 'engineering' info like the PSI needed. Source(s): CPR instructor for 10 years (American Red Cross, National Safety Council)
when in doubt, read your CPR almanac or ask your instructor.
