What is the appropriate action if a child's non-rebreather mask reservoir bag remains inflated during inhalation?

When a child's non-rebreather mask reservoir bag remains inflated during inhalation, adjusting the seal on the face mask is crucial. An adequately sealed mask ensures that the patient is receiving a high concentration of oxygen and prevents exhaled air from escaping. If the seal is not tight enough, the child may not be able to draw in the oxygen as intended, which can lead to inadequate oxygenation.

Maintaining an effective seal helps create a system where inhaled air comes primarily from the reservoir bag, maximizing the delivery of oxygen to the patient. This action is essential, especially in emergency situations where oxygen delivery is critical for the child's well-being.

While monitoring pulse oximetry is an important part of assessing a patient's oxygenation status, it does not address the immediate issue of mask fit. Increasing the oxygen flow can also be necessary, but if the mask isn't sealed properly, increasing the flow may not resolve the problem of insufficient oxygen delivery. Changing to an air-entrainment mask is not appropriate in this context, as non-rebreather masks are specifically designed for delivering high concentrations of oxygen, which would be compromised if switched to a different device.
