What should be done for an adult breathing at a rate of 6 breaths per minute?

In a scenario where an adult is breathing at a rate of 6 breaths per minute, this indicates bradypnea, which is an abnormally slow respiratory rate. At this level, the patient's ventilation may be inadequate, risking insufficient oxygen exchange and potential respiratory failure.

Providing ventilation via a bag-valve mask is the appropriate intervention to ensure that the patient receives adequate oxygenation and that carbon dioxide is expelled effectively. This is essential, particularly if the patient's overall clinical picture indicates reduced respiratory function or if they exhibit signs of compromised airway or altered mental status.

Options such as monitoring the patient’s heart rate or assisting in finding a comfortable position may be supportive but do not address the immediate need for proper ventilation. Additionally, while supplemental oxygen could be beneficial in some contexts, it does not correct the underlying issue of inadequate breathing. The primary goal in this situation is to restore effective ventilatory support, which is achieved by using a bag-valve mask.
