Compression-only versus conventional cardiopulmonary resuscitation
There are two types of CPR. Compression-only CPR (COCPR) is chest compression without mouth-to-mouth breathing. You should perform continuous chest compression at a rate of 100 to 120 per minute.
Conventional CPR combines mouth-to-mouth breath and chest compression. You should give 2 breaths followed by 30 chest compressions and then repeat the cycle.
