CPR cycle and rate of compressions

by Adam

The question was ...

CPR is in progress on an 80 year old man who has fallen from a ladder. He has no pulse and chest compressions are being initiated. Current AHA guidelines specify that this man should receive approximately how many compressions over a period of 2 minutes ?

Correct Answer is: 200 compressions

Current AHA guidelines specify 100 compressions per minute for adults and children


call me crazy, but in the first 2 minutes of CPR, you're supposed to complete 5 cycles at a rate of 100 compressions per minute.

the difference in the total is a result of time being included for breaths.

with five 30/2 cycles, doesn't that mean the total should be more like 150 ?



Here is a little info regarding compression and AHA guidelines

The major changes to the 2005 guidelines include:
Emphasis on effective CPR, chiefly on effective chest compressions with minimal interruptions

A single compression-to-ventilation ratio of 30:2 for all single rescuers for adults, children and infants (excluding newborns)

Each shock from an AED should be followed by two minutes of CPR starting with chest compressions

Each rescue breath should take one second and produce visible chest rise

Perform chest compressions at a rate of 100 compressions per minute for adults, children, and infants in cardiac arrest.

During courses and for course completion, students must deliver 30 chest compressions in less than 23 seconds when performing compressions and breaths at a 30:2 ratio. For a ratio of 15:2, students must deliver chest compressions in less than 11 seconds.
