For patients starting long-term oxygen therapy for chronic, severe hypoxemia at rest, the risk for hospitalization or death within one year is comparable with long-term oxygen therapy for 24 or 15 hours per day, according to a study published online Sept. 10 in the New England Journal of Medicine to coincide with the European Respiratory Society Congress, held from Sept. 7 to 11 in Vienna.
No advantage seen with long-term oxygen therapy for 24 versus 15 hours/day
