The depth of compressions is crucial for ensuring that blood is effectively circulated through the body: Adults: Compress the chest at a depth of at least 2 inches (5 cm) but not more than 2.4 inches (6 cm).This depth helps generate enough pressure to maintain blood flow while minimizing the risk of injury.
Find out more about the theory and applications of compression testing. . The data produced in a compression test can be used in many ways including: To determine batch quality; To determine consistency in manufacture; To aid in the design process; To reduce material costs and achieve lean manufacturing goals;
Rescuers should perform chest compressions for all ages at a rate of 100 to 120 compressions per minute (almost 2 compressions/second). 1,2,4,9,11 [CoSTR 2015/2020strong recommend, ation, very-low-certainty evidence] This does not imply that 100-120 compressions will be delivered each minute since the The cardiopulmonary resuscitation guidelines revised in 2015 recommend target chest compression rate (CCR) and chest compression depth (CCD) of 100–120 compressions per minute (cpm) and 5–6 cm, respectively. We hypothesized that the new guidelines are harder to comply with, even with proper feedback. This prospective .The theory test accidents and incidents category explained.

Remember these five points: Hand position: Two hands centered on the chest; Body position: Shoulders directly over hands; elbows locked; Compression depth: At least 2 inches; Rate of compressions: 100 to 120 per minute The “cardiac compression” theory of forward blood flow during chest compressions for cardiac arrest presumes that blood is squeezed from the heart into the arterial and pulmonary circulations, with closure of the mitral and tricuspid valves, preventing retrograde blood flow, and opening of the aortic and pulmonary valves in response to . Historically, two theories describing the mechanisms by which forward blood flow is achieved during chest compressions have been put forth: the cardiac pump theory and the thoracic pump theory.
