Which technique should you use when performing CPR on a 4-month-old infant alone?

The recommended technique for performing CPR on an infant, particularly a 4-month-old, focuses on utilizing a method that is both effective and safe given the size and fragility of their body. The two-finger technique involves using the index and middle fingers to provide compressions just below the nipple line, allowing for proper blood flow during cardiac arrest.

Additionally, using a pocket mask for providing ventilations is crucial, as it helps create a seal and delivers air more effectively without the risk of potentially harming the infant’s airways through improper techniques. Ventilation is also an integral part of resuscitation in infants, making this approach comprehensive.

This method prioritizes the infant's safety and the need for adequate compressions and oxygenation, which are essential components of effective CPR. In contrast, other techniques might not adequately provide the necessary chest compressions or ventilations required for an infant in a resuscitation scenario.
