When providing care for an adult in respiratory arrest, what action is appropriate?

Delivering 1 ventilation every 6 seconds is appropriate for an adult in respiratory arrest because this rate aligns with current guidelines for providing rescue breaths in adult patients. The recommended ratio for ventilation in adults who are not breathing but have a pulse is to give breaths every 5 to 6 seconds, which provides adequate oxygenation while minimizing the risk of causing airway obstruction or hyperventilation.

In this scenario, the goal is to ensure the patient receives enough oxygen while allowing for sufficient time between breaths. This approach helps to maintain effective ventilation and oxygen delivery, which is critical in situations of respiratory arrest where the patient's heart may still be beating, but they are unable to breathe.

Understanding the timing and frequency of ventilation is crucial in providing effective care and can make a significant difference in patient outcomes during emergencies.
