How is oxygen used for COPD management?

Donna Hill Howes, RN
Family Practitioner

Oxygen therapy for 15 hours a day or more can help people live longer with chronic obstructive pulmonary disease (COPD) and very low levels of oxygen in their blood. A doctor can measure the amount of oxygen in the blood by taking blood from an artery or by using a device called an oximeter. Oxygen therapy is usually recommended if a person's oxygen saturation is 88% or lower, or if the PaO2 measurement (partial pressure of oxygen in arterial blood) is at or below 55 mm Hg. These levels need to be confirmed twice over 3 weeks.
