What is the recommended flow rate for a non-rebreather mask?

The recommended flow rate for a non-rebreather mask is 10 to 15 liters per minute. This flow rate is crucial for ensuring that the patient receives a high concentration of oxygen, which is the primary goal when using this type of mask. A non-rebreather mask is designed to deliver almost 100% oxygen to the patient, making it essential to maintain a high flow rate that can keep the reservoir bag inflated during inhalation.

Using a flow rate below the recommended levels would lead to less oxygen being available for the patient and could result in the reservoir bag collapsing during inhalation, thereby compromising the delivery of oxygen. The specified flow range achieves the necessary pressure to keep the bag inflated and allows for a high concentration of oxygen to be available for respiratory support, making it effective for managing conditions such as severe hypoxia.
