What is the correct rate of ventilation delivery for an adult in respiratory arrest?

The proper rate of ventilation delivery for an adult in respiratory arrest is 1 ventilation every 6 seconds. This rate allows for sufficient time for adequate alveolar ventilation and oxygenation while preventing complications associated with overly rapid ventilation, such as barotrauma or hyperventilation.

In practical terms, delivering breaths at this interval ensures that each breath is effective, allowing the lungs to adequately fill and ensuring that the oxygen is delivered properly to the patient. The goal is to optimize oxygenation while minimizing the risk of complications, which is why this particular rate is established in guidelines for the management of respiratory arrest.

Other options suggest different intervals that do not align with current emergency guidelines for adult resuscitation, promoting unsuitable rates of ventilation that could either hinder effective respiration or disrupt the patient’s cardiac rhythm.
