I think the 15:2 and 5:1 are cut out of the lay CPR. However, IIRC, professional CPR still teaches a higher rate once an airway is established (Combitube, endotracheal, etc). I don't remember if it's 5:1 or what, but that's b/c I haven't had an arrest in the field for probably 3 years. Hospital is different, cuz the respiratory tech is bagging while someone bangs on the chest.
