how deep should chest compressions be

The recommended depth for chest compressions during CPR for adults is about 2 to 2.4 inches (5 to 6 cm). This depth ensures effective blood circulation without causing excessive injury. Compressing at least 2 inches but not more than 2.4 inches is advised to maintain high-quality CPR, with a compression rate of 100 to 120 per minute for optimal results. For children and infants, the compression depth is less, tailored according to their body size (about 2 inches for children and 1.5 inches for infants).
