What should be checked regarding the reservoir of a non-rebreather mask?

It should be at least half full
It should be less than half full
It should never be less than 2/3 full
It should be completely full

The correct answer is: It should never be less than 2/3 full

When assessing the reservoir of a non-rebreather mask, it is critical that it should never be less than two-thirds full. This is because the purpose of the reservoir bag is to provide a sufficient volume of oxygen to the patient and to ensure that they receive high concentrations of oxygen during respiration. A reservoir bag that is consistently less than two-thirds full can indicate that there is inadequate flow of oxygen or that the mask is not properly sealing on the patient’s face, which can lead to decreased effectiveness of oxygen delivery. If the reservoir bag is not adequately filled, it will not maintain pressure and flow during inhalation, which may cause the patient to inhale room air instead of the desired high-flow oxygen. This can significantly compromise the management of patients in respiratory distress or those requiring high-flow oxygen therapy. Therefore, ensuring that the bag is adequately filled is essential for effective treatment.
