What is the flow rate for low flow oxygen therapy?

The flow rate for low-flow oxygen therapy is typically between 1 to 6 liters per minute (LPM). This range is essential for providing supplemental oxygen in situations where patients do not require high concentrations of oxygen. Low-flow oxygen delivery systems, such as nasal cannulas and simple face masks, are designed to deliver oxygen in this manner, allowing for variable atmospheric air to mix with the oxygen being delivered.

Using low flow rates helps to ensure that the patient's breathing is not overly assisted, promoting a more natural respiratory pattern. This is particularly beneficial for patients with chronic conditions or those who are experiencing mild to moderate respiratory distress. The other ranges listed, which exceed 6 LPM, are associated with high-flow oxygen delivery systems that provide a higher concentration of oxygen and are intended for different clinical situations where more precise oxygen delivery is necessary.
