Cardiopulmonary Resuscitation (CPR) Practice

The statement is true because chest compressions during CPR are essential for maintaining blood circulation in a person experiencing a cardiac event. The compression depth of 1/3 to 1/2 the width of the chest allows for effective heart compression, which is critical for generating adequate blood flow to vital organs. Allowing for full chest recoil after each compression is equally important as it enables the heart to refill with blood between compressions. Insufficient recoil can lead to reduced blood flow and diminished effectiveness of the CPR process. This guideline applies broadly across various age groups, although specific techniques may vary slightly for infants and children. Ensuring proper depth and full recoil helps maximize the efficiency of CPR and raises the chances of survival till advanced medical help arrives.
