When providing ventilations to an adult patient in respiratory arrest, the recommended practice is to deliver one ventilation every 6 seconds. This rate allows for adequate oxygenation without overinflating the lungs and potentially causing complications such as barotrauma. Each ventilation should be given with sufficient volume to make the chest rise visibly, indicating that the air is reaching the lungs effectively.

This timing is based on the need to balance providing enough air to support the patient's breathing while allowing a proper duration between breaths for the gas exchange to occur. Ventilating too frequently can lead to inadequate exhalation and carbon dioxide accumulation, which can worsen the patient's condition. Therefore, delivering a ventilation every 6 seconds is aligned with current guidelines to ensure both effective ventilation and patient safety.
