To determine whether studies of breathing and oxygenation during sleep are clinically useful, we have assessed whether the detection of excess nocturnal hypoxemia in patients with chronic obstructive pulmonary disease (COPD) is of prognostic importance. Ninety-seven patients with COPD were followed for 32 to 108 (median, 70) months after studies of overnight oxygenation. Significant relationships (p less than 0.001) were obtained between mean oxygen saturation (SaO2) asleep and awake. There w...Expand abstract
