摘要: We recorded the electroencephalogram, electrooculogram, electromyogram, and ear oxygen saturation (SaO2) during sleep in 20 patients with chronic bronchitis emphysema, 13 of whom had a low arterial PO2 elevated PCO2 (“blue bloated”) 7 relatively normal (“pink puffing”), compared findings these 9 healthy subjects similar age. All slept for 2 nights there was no difference between groups total period. The lower stable SaO2 than subjects, “blue bloated” having significantly more hypoxemic episodes (p < 0.01). Transient nocturnal hypoxemia commonest REM both its duration not related to any variable examined. shorter periods brief arousal occurring night 0.02). Six representative pat...
