What is the typical flow rate range for low-flow oxygen systems?

Low-flow oxygen systems are designed to deliver oxygen in a concentrated manner, typically for patients who require supplemental oxygen but do not need high flow rates. The common flow rate range for these systems is usually between 1 to 6 liters per minute (L/min). This range allows for effective oxygen delivery while still enabling the patient to breathe room air, as low-flow systems mix the supplied oxygen with ambient air.

Using flow rates above this range may lead to a risk of providing too much oxygen to patients who do not require it, especially in cases like chronic obstructive pulmonary disease (COPD) where higher oxygen levels can be detrimental. Thus, the specific range of 1-6 L/min ensures a balance between providing supplemental oxygen and allowing the patient to breathe naturally, making it essential in managing low-flow oxygen therapy correctly.
