If the reservoir bag fully collapses when the patient inhales, what should you do?

When a reservoir bag fully collapses during a patient's inhalation, it indicates that the patient is not receiving adequate oxygen, as the bag should remain partially inflated to provide a steady flow of oxygen during breaths. Increasing the flow rate is the appropriate action in this scenario because it enhances the delivery of oxygen to the patient, ensuring they can receive a sufficient supply of oxygen with each breath.

This action addresses the immediate need for oxygen and helps prevent further respiratory distress. Monitoring the flow rate and ensuring that the patient's breathing pattern receives support is crucial, especially in emergencies, where hypoxia can lead to serious complications. Other responses, like changing the oxygen system or encouraging the patient to breathe deeper, may not effectively resolve the issue of the collapsed bag in an immediate manner, as they could introduce unnecessary delays or complications.
