BLS/CPR continues to be watered down by AHA. Perhaps simplification is a good thing, for the general public.
For nursing students, EMTs of all stripes, YMCA lifeguards . . wouldn't you want to know what they could teach you, in a day?
Oh--you don't have a day. Oh, well, in that case, just how much did you wish to know?
Just what they could expose you to, on-line, in 30 minutes or so?
And you get your cert., & you're "good to go"? Did you merely want the cert? or did you actually want to know smth about the subject?
OK, get what you can, in the time you have "available". Sure hope you don't need it, for real, And, I especially hope, your patient doesn't actually need it, when you are presented with the absolute need, for smth you may not really know all that much about.
