The most important aspects of CPR are: few interruptions of chest compressions, a sufficient speed and depth of compressions, completely relaxing pressure between compressions, and not ventilating too much. [22] It is unclear if a few minutes of CPR before defibrillation results in different outcomes than immediate defibrillation. [23]
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.
CPR consists of chest compressions followed by rescue breaths - for single rescuer do 30 compressions and 2 breaths (30:2), for > 2 rescuers do 15 compressions and 2 breaths (15:2). The rate of chest compressions should be 100-120 compressions/min and depth should be 1.5 inches for infants and 2 inches for children. [citation needed]
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. [30]

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 ...
I’ve seen some eye rolls about shocking asystole, but the real knee slappers for me are the pathetic chest compressions. They never get the rate or depth right. #22
There are multiple factors during cardiopulmonary resuscitation (CPR) and defibrillation that are associated with success of achieving return of spontaneous circulation. . One of the factors in CPR is the chest compression fraction, which is a measure of how much time during cardiac arrest are chest compressions perfor
