Recent studies on patients with stable obesity-hypoventilation syndrome have raised concerns about hyperoxia-induced hypercapnia in this population. This study aimed to evaluate whether a higher oxygen saturation target would increase arterial partial pressure of carbon dioxide (PaCO₂₎ in obese patients after coronary artery bypass grafting surgery (CABG).

肥胖症患者心脏手术后高氧血症引起的高碳酸血症的评估：保守和自由氧给药的随机交叉比较

最近对稳定的肥胖-通气不足综合征患者的研究引起了人们对高氧血症引起的高碳酸血症的关注。这项研究旨在评估更高的氧饱和度目标是否会增加冠状动脉旁路移植术（CABG）后肥胖患者的动脉二氧化碳分压（PaCO ₂）。
