People with COPD who need and use continuous oxygen therapy 24 hours a day tend to have a longer lifespan than those who use it only while awake (15 hours per day). In turn, individuals who use oxygen therapy 15 hours per day do better than those who use it only while they are sleeping. Publication Review By: Peter B. Terry, M.D., M.A. Published: 08 Aug 2011
Oxygen saturation is a term referring to the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent.If the level is below 90 percent, it is considered low resulting in hypoxemia. Blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed.Continued low oxygen levels may lead to respiratory or cardiac arrest.f the level is below 90 percent, it is considered low resulting in hypoxemia. Blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. Continued low oxygen levels may lead to respiratory or cardiac arrest.
