In a case of respiratory arrest, how often should you squeeze the bag while ventilating a patient?

In a case of respiratory arrest, the guidelines for bag-valve-mask (BVM) ventilation recommend giving ventilations every six seconds for an adult patient. This rate allows sufficient time between breaths to prevent hyperventilation and to maintain adequate oxygenation. When providing ventilations at this rate, it's essential to deliver a volume that results in visible chest rise, ensuring effective ventilation of the lungs.

The rationale behind achieving barely visible chest rise focuses on avoiding excessive pressure and volume that could lead to injury or complications, such as gastric inflation or barotrauma. By aiming for effective but not overly aggressive ventilations, the goal is to provide adequate support while minimizing the risks associated with improper ventilation techniques.

In summary, administering ventilations every six seconds while ensuring effective chest movement correlates well with the need to provide adequate oxygenation in a patient experiencing respiratory arrest.
