More and more patients have obesity-hypoventilation syndrome (OHS) because of the increasing prevalence of obesity. The accuracy of transcutaneous P_CO2 (P_tcCO2 ) has recently been validated. However, no study evaluated the interest of measuring systematically nocturnal P_tcCO2 in the follow-up of patients with OHS and home mechanical ventilation to detect residual nocturnal hypoventilation. We aimed to evaluate the contribution of nocturnal P_tcCO2 to assess nocturnal hypoventilation compared with current routine examinations, that is, daytime arterial blood gases and nocturnal pulse oximetry.

经皮 PCO2 在肥胖通气不足综合征中的作用。


由于肥胖患病率不断增加，越来越多的患者患有肥胖通气不足综合征（OHS）。经皮 P _{CO 2} (P _{tcCO 2} ) 的准确性最近已得到验证。然而，尚无研究评估在 OHS 和家庭机械通气患者随访中系统测量夜间 P _{tcCO 2}的重要性，以检测残余夜间通气不足。我们的目的是评估夜间 P _{tcCO 2}与当前常规检查（即日间动脉血气和夜间脉搏血氧饱和度）相比，对评估夜间通气不足的贡献。
