What is the minimum number of chest compressions that should be delivered per minute to a 4-month-old infant?

The correct answer is: 100

The recommended minimum number of chest compressions for a 4-month-old infant during cardiopulmonary resuscitation (CPR) is 100 per minute. This guideline is established to ensure that blood circulation is maintained effectively during cardiac arrest. Performing compressions at this rate allows for sufficient blood flow, which is crucial for oxygen delivery to vital organs. In infants, the physiological response to CPR can differ from that of older children and adults. The high rate of compressions is necessary due to the smaller size of an infant's heart and the limited volume of blood that can be circulated. It is essential to maintain this compression rate while ensuring they are of adequate depth and allow for full chest recoil between compressions. This combination optimizes the chances of resuscitation for an infant experiencing a cardiac event.
