CPR involves chest compressions for adults between 5 cm (2.0 in) and 6 cm (2.4 in) deep and at a rate of at least 100 to 120 per minute. [2] The rescuer may also provide artificial ventilation by either exhaling air into the subject's mouth or nose ( mouth-to-mouth resuscitation ) or using a device that pushes air into the subject's lungs ...
After defibrillation, chest compressions should be continued for two minutes before another rhythm check. [30] This is based on a compression rate of 100-120 compressions per minute, a compression depth of 5–6 centimeters into the chest, full chest recoil, and a ventilation rate of 10 breath ventilations per minute.

An adequate ratio of high quality chest compressions and rescue breaths are crucial. An automated external defibrillator (AED) machine is essential during resuscitation. Defibrillation during the first 3 to 5 minutes during resuscitation can produce survival rates as high as 50 to 70%.
"Stayin' Alive" was used in a study to train medical professionals to provide the correct number of chest compressions per minute while performing CPR. The song has around 103 beats per minute, and 100–120 chest compressions per minute are recommended by the British Heart Foundation [17] [18] and endorsed by the Resuscitation Council (UK). [19]
Squeezing the bag once every 5 to 6 seconds for an adult or once every 3 seconds for an infant or child provides an adequate respiratory rate (10–12 respirations per minute in an adult and 20 per minute in a child or infant). [5] Bag valve mask with BV filter
