What is the correct one-responder cycle for an infant during CPR?

The correct one-responder cycle for an infant during CPR involves performing 30 compressions followed by 2 ventilations. This cycle is part of the guidelines established for basic life support specific to infants, which emphasizes a ratio of compressions to breaths that is adapted to their smaller body size and metabolic needs.

In this context, the compressions are delivered at a rate of about 100-120 compressions per minute, which is consistent with the recommendation for effective CPR. The ventilations provided afterward are intended to ensure that the infant receives enough oxygen, which is critical in situations of respiratory or cardiac emergencies. The emphasis on this specific ratio allows for a balance between maintaining blood circulation through compressions and providing necessary oxygenation through ventilations.

Other ratios, such as 15 compressions to 2 ventilations or smaller ratios of compressions to ventilations, do not align with established guidelines for infant CPR and may not effectively address the needs of an infant in cardiac arrest.
