What is the percentage of O2 in oxygen?
Standard oxygen sources can deliver from ½ 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 – 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 – 37% O2.
