American Lifeguard Practice Exam

At what rate should rescue breathing be performed for an infant?

1. 1 rescue breath every 2 seconds.

2. 1 rescue breath about once every 3 seconds.

3. 1 rescue breath about once every 5 seconds.

4. 1 rescue breath every 4 seconds.

The correct answer is: 1 rescue breath about once every 3 seconds.

Rescue breathing for an infant should be performed at a rate of approximately one breath every three seconds. This rate ensures that the infant receives sufficient oxygen without causing over-inflation of the lungs or potential injury. Infants have a smaller lung capacity, and their respiratory needs differ significantly from those of older children and adults, which is why it is crucial to adjust the rescue breathing technique accordingly. In addition, using this specific rate helps to maintain a balance between providing adequate ventilation and allowing for sufficient time between breaths to avoid stress on the infant's respiratory system. Understanding this rate is essential for lifeguards and rescuers, as timely and effective rescue breaths can be life-saving in emergency situations involving infants.
