How many initial compressions followed by ventilations are appropriate for infants in most cases of cardiac arrest?

30 compressions followed by 2 ventilations
15 compressions followed by 2 ventilations
5 compressions followed by 1 ventilation
10 compressions followed by 1 ventilation

The correct answer is: 15 compressions followed by 2 ventilations

For infants in cases of cardiac arrest, the recommended initial sequence involves performing 15 compressions followed by 2 ventilations. This approach is part of the high-quality cardiopulmonary resuscitation (CPR) technique suitable for infants, which emphasizes not only the importance of chest compressions but also the timely administration of breaths. In the context of BLS, using 15 compressions followed by 2 ventilations is essential because infants have different physiological needs compared to adults. Infants are more prone to respiratory issues, and providing ventilations after a set of compressions helps ensure that oxygen reaches the vital organs quickly while also promoting circulation through effective compressions. This sequence helps to balance the need for oxygenation and circulation, ensuring that even in a critical situation like cardiac arrest, the care provided is tailored to the specific needs of infants. Understanding this sequence is crucial for anyone providing care to infants experiencing cardiac arrest.
