How should chest compressions be given to an infant?

When providing chest compressions to an infant, the correct technique involves using two fingers placed in the center of the chest, just below the nipple line. This method is preferred because infants have a relatively small and fragile chest cavity, which requires a gentler approach compared to adults and older children. The two-finger technique allows for adequate compression while minimizing the risk of injury to the infant's delicate organs and ribs.

Compression depth for infants should be about one-third the depth of the chest, which is typically around 1.5 inches or 4 centimeters. The rate of compressions should also be considered, aiming for 100 to 120 compressions per minute. This method effectively circulates blood during cardiac arrest situations, helping to ensure oxygen delivery to vital organs.

The other options do not follow the appropriate guidelines for infant CPR, as using one hand or the heel of the hand can apply excess force and may not achieve the necessary depth, potentially leading to injury. Similarly, compressing above the navel is not an effective placement for performing CPR, as it does not target the heart adequately.
