What is the flow rate of oxygen for a partial rebreather mask?

A partial rebreather mask is designed to deliver a higher concentration of oxygen to patients who are experiencing respiratory distress or low oxygen saturation levels. The correct flow rate for a partial rebreather mask is typically between 10 to 15 liters per minute. This flow rate helps ensure that the mask can maintain a reservoir of oxygen while also allowing some of the exhaled air to be rebreathed, increasing the overall oxygen concentration the patient receives.

This high flow rate is essential because it compensates for the mask's construction, which includes a reservoir bag that partially fills with oxygen. If the flow rate is too low, the bag will not adequately refill, which can lead to suboptimal oxygen delivery to the patient. Therefore, providing the correct flow rate is crucial for achieving effective gas exchange and ensuring that the patient receives sufficient oxygen.
