What is the primary use of a non-rebreather mask?

The primary use of a non-rebreather mask is to provide high concentrations of oxygen to patients who are in respiratory distress or have conditions that significantly impair their ability to maintain adequate oxygen levels. This type of mask delivers oxygen at a flow rate of at least 10-15 liters per minute, allowing for a high concentration of oxygen to be inhaled by the patient.

The design of the non-rebreather mask includes a reservoir bag that fills with oxygen, and the mask features one-way valves that prevent the exhaled air from mixing back into the bag. This setup effectively allows the patient to breathe in almost pure oxygen while minimizing the risk of rebreathing carbon dioxide.

In situations where a patient is experiencing severe hypoxia or respiratory issues, the use of a non-rebreather mask is critical for improving oxygen saturation levels quickly and efficiently. This makes it an essential tool for EMTs and healthcare providers in emergency care situations.
