Actually, I've been thinking the same.
Administration of CPR =/= no pulse/no breathing necessarily. CPR training dictates to check for these things, but if you are unsure (faint pulse) or if breathing is irregular (gasps and such), administer CPR. Starting CPR is deemed more important than waiting to double-check these things.
To me, it is more important how long FD MAY have been without oxygen before CPR was started, as well as the concentration of carbon monoxide in his body. Once CPR was started, oxygen was being forced into his system.
Also, random, but since it was brought up previously, I've seen some talking about the possibility of FC "faking" being unconscious, as well as the forcefulness of the CPR administered. First of all, anyone familiar with quality CPR will tell you that faking unconsciousness to the point of receiving CPR is a BAD idea. The depth and force of chest compressions done correctly is painful and can possibly break bones.
Secondly, I don't think that CPR was forceful; I think it was CPR administered correctly. Quality CPR is significantly more violent than what the general public is led to believe in media.
All-in-all, I think those first responders did a terrific job yesterday.
