Rich, what is the new CPR method?
IS a Diving Reflex victim pulseLESS or is it so shallow as to be undetectable?
Here's the re-revision of the 2005 AHA guidelines: http://www.heart.org/idc/groups/hear...ucm_317350.pdf
.... although several state EMS bureaus/agencies, for organized EMS responders, have applied even more rigorous (pit crew/extreme high quality) type of CPR on top of the general AHA standards. It 'works'; 'saves' are at a much higher success rate.
Like deep hypothermia incidents, true MDR usually has a very low to nil pulse pressure and a very low (bradycardic) rate --- can be undetectable, unless ECG, etc. is employed (but we rarely waste time in applying ECG initially). Even with electronic pulse / PO2 instruments, the feeble pulse (if any) and low body core temperature prevent appropriate monitoring. So, as with any deep hypothermic event, no one is field-pronounced as dead until "warm and dead"; obvious severe trauma cases are usually excluded due their extremely low/rare/dismal success rates.
In all non-trauma pulselessness, the key for survival is early and 'quality' CPR / early defibrillation .... followed by the quick
arrival of Advanced Life Support - ALS. Its quite amazing and remarkable of the increased rate of 'code' success when such is applied early
and without delay .... makes the paramedics quite happy to arrive and find a potentially viable patient to work upon. We'd rather arrive and find a 'CPR saved' patient due to 'quality CPR' being performed and have little to do than not. Such makes a BIG difference in many cases.
Most emergency response dispatch centers will even instruct over the phone on how to do the 'push fast and push hard' (compressions only
) version of CPR ... definitely adds to the success rate.
