The concentrator has worked great for decreaseing drops in oxygen at night
The concentrator has worked great for me. I wear an spo2 monitor to monitor oxygen drops and since starting my use of the concentrator my o2 drops have improved dramatically and my oxygen levels are staying above 95% most of the night. Prior to using the concentrator I was frequently having drops below 90%. Not only that but the number of drops >4% and >3% has improved dramatically, for example from 44 drops >4% and 76 drops >3% to 6 drops >4% and 11 drops >3%! I am also sleeping fewer hour to feel refreshed!
