What is the maximum depth for cardiopulmonary resuscitation compressions in infants?

The maximum depth for cardiopulmonary resuscitation compressions in infants is about 4 cm (1.5 inches). This depth is essential because it ensures that compressions are effective in creating sufficient pressure to circulate blood during cardiac arrest, while also being gentle enough to avoid causing injury to the infant's fragile rib cage and internal organs.

Research and guidelines suggest that at this depth, the compressions are more likely to achieve adequate blood flow to vital organs without exceeding the physical limits of an infant's anatomy. It is critical to maintain this depth rhythmically at a rate of at least 100 to 120 compressions per minute, balancing both the force applied and the frequency to optimize the chances of a successful resuscitation outcome.
