When providing ventilations to an adult patient in respiratory arrest, what is the recommended frequency for delivering ventilations?

The recommended frequency for delivering ventilations to an adult patient in respiratory arrest is 1 ventilation every 5 to 6 seconds. This rate allows for adequate oxygenation while preventing potential complications such as over-inflation of the lungs. Delivering ventilations at this frequency ensures that sufficient time is allowed for the chest to rise and for the carbon dioxide to be expelled, which is essential for maintaining proper respiratory function and preventing hypoxia.

This timing also takes into account the need to prevent excessive ventilation, which can lead to increased intrathoracic pressure and decreased venous return to the heart, thus potentially compromising circulation. Proper technique and timing during rescue breathing are crucial components of basic life support procedures, particularly when addressing respiratory arrest in adults.
