The quality of chest compressions during cardiopulmonary resuscitation (CPR) is crucial for maintaining blood flow to vital organs. Effective compressions should be at a depth of about 2 inches and at a rate of 100 to 120 compressions per minute. Proper hand placement and allowing full chest recoil between compressions are also important to maximize blood circulation. Additionally, the compressions should be performed on a firm surface to ensure effectiveness. Minimizing interruptions in compressions, such as during defibrillation or when giving rescue breaths, helps maintain blood flow. Continuous monitoring and adjusting technique can improve the overall quality of CPR.
