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 ...
The compression depth and force varies per patient. The chest displacement equals a 20% reduction in the anterior-posterior chest depth. The physiological duty cycle is 50%, and it runs in a 30:2, 15:2 or continuous compression mode, which is user-selectable, at a rate of 80 compressions-per-minute.
How do you know if someone needs CPR? If the person is talking and breathing, then they don’t need CPR, per the CDC. Signs that someone may be experiencing cardiac arrest and therefore needs CPR ...
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.

"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]
While CPR is performed (which may involve either manual chest compressions or the use of automated equipment such as the AutoPulse or LUCAS device), members of the team consider eight forms of potentially reversible causes for cardiac arrest, commonly abbreviated as "6Hs & 5Ts" according to 2005/2010 AHA Advanced Cardiac Life Support (ACLS).
The guidelines also changed the duration of rescue breaths and the placement of the hand on the chest when performing chest compressions. These changes were introduced to simplify the algorithm , to allow for faster decision making and to maximize the time spent giving chest compressions; this is because interruptions in chest compressions have ...
The LUCAS device delivers high-quality compressions at a continuous rate, while up to a third of manual compressions can be incorrect. [9] In 2013, a 68-year-old male made a complete recovery, including no intellectual or neurological deficits, after an out-of-hospital cardiac arrest after 59 minutes of mechanical compressions on a LUCAS device ...
