The current recommendations for CPR are that the rate of cardiac compressions should be 100 compressions per minute, regardless of whether the patient is a adult or infant.
If there is only one person doing CPR, do 15 compressions to two quick breaths.
If there are two people, have one person doing compressions and the other doing breaths. Do one breath for every 5 compressions. Do not stop doing chest compressions for breaths.
Every minute or two, stop for a few seconds to check for spontaneous breathing and a pulse.
If there are more than two people around, have someone occasionally check the femoral pulse to ensure that there is good blood circulation.
