What is the recommended flow rate for delivering oxygen to a patient using a non-rebreather mask?

The recommended flow rate for delivering oxygen to a patient using a non-rebreather mask is 15 liters per minute (LPM). This high flow rate is crucial because it ensures that the bag attached to the mask remains inflated, which allows for the delivery of a high concentration of oxygen to the patient.

Non-rebreather masks are designed to provide close to 100% oxygen when used properly. The high flow rate helps to replace the expelled carbon dioxide and maintains the reservoir bag's inflation, preventing the inhalation of ambient air, which could dilute the oxygen being delivered.

Using a flow rate lower than 15 LPM could result in inadequate oxygen delivery, as the reservoir bag may not remain fully inflated, thereby reducing the effectiveness of the mask in supplying sufficient oxygen to the patient. Therefore, 15 LPM is the standard recommendation for optimal oxygenation during critical situations.
