How much oxygen do you need for oxygen therapy for heart failure?

ANSWER

Your doctor will measure your oxygen level with either a blood test or a device called a pulse oximeter.

Then she'll give you a prescription for oxygen therapy, just like you’d get for medicine. It tells you how much oxygen you need and when to take it. Follow these directions closely. Too little oxygen can damage your heart and brain. Too much could slow your breathing and cause other issues.
