What is the best technique for performing infant CPR?

The best technique for performing infant CPR focuses on using gentle compressions and ensuring an effective seal for rescue breaths. When performing CPR on an infant, it is crucial to use two fingers for chest compressions, which should be both gentle and delivered at a rate of about 100 to 120 compressions per minute. This approach minimizes the risk of injury to the infant's fragile ribcage and organs.

Additionally, when giving rescue breaths, it is important to create a proper seal over the mouth and nose of the infant to ensure that the breaths are effective and deliver oxygen adequately. This method helps in safely providing the necessary ventilation while maintaining high-quality compressions.

Other options, while they may seem valid in some contexts, don’t align with established infant CPR protocols. Using one hand is inappropriate because it does not provide the needed force and is less controlled. Quick, forceful breaths can also pose a risk of over-inflating the lungs, which is particularly dangerous in infants. Lastly, performing CPR without checking for responsiveness would hinder appropriately assessing the situation and determining the need for CPR in the first place. Therefore, the technique involving gentle compressions with two fingers and creating a tight seal for rescue breaths is the most effective and safest for infants.
