What is the proper technique for administering oxygen via a non-rebreather mask?

Administering oxygen via a non-rebreather mask requires ensuring a tight seal and delivering oxygen at the appropriate flow rate. This mask is designed to provide a high concentration of oxygen to the patient, which is critical in situations of severe respiratory distress or hypoxia.

A tight seal is essential because it prevents room air from being inhaled, allowing for the maximum amount of concentrated oxygen to reach the patient. The standard flow rate of 10-15 liters per minute is necessary to keep the reservoir bag inflated, ensuring that the patient receives a sufficient supply of oxygen with each breath.

This technique is particularly important in emergency situations, as maintaining high levels of oxygen can be a life-saving intervention. Proper utilization of the non-rebreather mask aligns with best practices in pre-hospital care and is especially relevant for conditions like severe asthma, COPD exacerbation, or trauma where oxygenation is critically compromised.
