作者报导睡眠呼吸障碍患者应用非创伤性经皮CO_2计的情况。共观察睡眠呼吸暂停综合征3例及慢性呼吸功能不全4例。资料表明呼吸功能不全患者在睡眠时血气紊乱较睡眠呼吸暂停患者来得重,并表职经皮CO_2分压(Ptc CO_2)之增加主要与睡眠深度有关,而与单纯呼吸暂停无关。呼吸暂停3例中只2例的Ptc CO_2在睡眠时有轻度增高而呼吸功能不全患者 The authors report the use of non-invasive percutaneous CO_2 in patients with sleep-disordered breathing. A total of 3 cases of sleep apnea syndrome and 4 cases of chronic respiratory insufficiency were observed. Data show that patients with respiratory insufficiency during sleep dysphoric disorder than sleep apnea patients more seriously, and epidural CO 2 partial pressure (Ptc CO 2) increased mainly with the depth of sleep, but not with simple apnea. Only 3 of the 3 patients with apnea had mild Ptc CO_2 during sleep, whereas patients with respiratory insufficiency
