I'm not sure if they are always different, but it seems like the AHA and Red Cross have different opinions on how to execute emergency assistance such as CPR. I thought CPR for infant, child and adult is done the same way for both AHA and RC, but I guess not.
I have been certified for CPR/AED and the sorts with AHA, but I am also in an EOP program with kaiser, and they had us get CPR/AED and first aid certified today by a person from the red cross. All I know is, the instructor for the red cross showed us outdated methods, and other nuances I don't care to mention.
Maybe the instructor was mediocre and knew only out of date stuff... idk.
But we didn't even cover two person CPR, bag valve mask usage, we didn't thoughroughly cover the full spectrum of choking, or use of the AED (which is a no brainer anyway). Not only that, but she didn't even test us on the skills (learned in one day).
That Red Cross instructor basically handed out those CPR and first aid cards like candy.
Which is sad.
