The flow rate o f oxygen is usually adjusted to increase or decrease the amount of oxygen that patients are receiving. Standard oxygen sources can deliver from Â½ liter per minute of O2 to 5 liters/minute (L/min). Every liter/minute of oxygen increases the percentage of O2 the patient breathes by 3 â 4 %. Room air is 21% O2. So if a patient is on 4 L/min O2 flow, then he or she is breathing air that is about 33 â 37% O2. The normal practice is to adjust O2 flow for patients to be comfortably above an oxygen blood saturation of 90% at rest. It is often, however, the case that patients need more oxygen for exercise.
