Jeff your right in some respects, as a CPR Instructor we teach in the Heart Start Program just compressions if 1:1(after checking to see if the patient is breathing),if 2:1 we teach to do rescue breathing with the new protocols of 30:2 and 100 compressions a minute, (five rounds equals 2 mins the American Heart recommends before switching rescuers). American Heart Association recommends more compressions then breaths (see 2005 AHA Guidelines for CPR in Winter Issue Emergency Cardiovascular Care). The 2005 study indicated that keeping blood circulating to the heart for a longer time was more beneficial then stopping after 15 compressions for two breaths.
Any help I can give just ask
