I don't really think you are going to tire out sooner, you are only doing a few compressions more a minute. The big thing is not to stop and interupt compressions for ventilations. Everytime you stop and quit compressions you have to build up thoracic pressure again before blood even starts to circulate to the brain. So if you do 15 at a time you only pump 8-7 times. If you go for 30 pumps you pump 20-22 times instead of 15 times. Less oxygen in the lungs, but more oxygenated blood circulating to the brain. So in that regard it makes a lot of sense.

Has anyone seen the AHA guideline changes:
BLS, 30-2 compression to ventilation
ACLS, 1 shock then 2 minutes of CPR then the 2nd shock
How could the science have been that far off to have changes this drastic over 4 years???
