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
Studies show that if you meet the criteria for continuous oxygen use, using it less than 18 hours a day is probably equivalent to using none at all. If your doctor prescribes 24-hour daily oxygen therapy you should try to use it as close to 24 hours a day as practical. Of course there are times you may need to take it off, when you shave or put on make-up or do other daily hygiene. This is not harmful for short periods of time.
