How much oxygen do I need if I have a lung disease?

Lyall A. Gorenstein, MD
Thoracic Surgery (Cardiothoracic Vascular)
Your doctor will prescribe the appropriate amount of oxygen for you to use based upon the results of your Arterial Blood Gases (ABG) and pulse oximetry tests. You may require a higher dose when exercising or performing difficult activities than when you are at rest or sleeping. Typically a prescription will be between 1-6 l/m of oxygen by flow meter.
