题目：

患者女，67岁，因“COPD恶化和肺炎”住院。期间行气管内插管机械通气。虽然临床症状好转，但试图停止机械通气时不成功。住院期间行气管造口术15d。现医师希望行非侵入性通气。血氧计监测血氧饱和度（SpO2），红外线二氧化碳监测仪连接到通气装置监测终末潮气二氧化碳分压（PETCO2）。第15天实验室检查：pH7.41~7.45，FiO20.40，HCO332~36mmol/L，COHb1.5%~1.8%，PaCO256~63mmHg，高铁血红蛋白（MetHb）0.8~1.0，PaO270~88mmHg，Hb132~134g/L，SaO290%~93%。

第16天，SpO289%~92%，PETCO235~40mmHg。PaCO2和PETCO2不同的最大原因可能是（）

A.通气回路间断漏气

B.高FIO2导致PETCO2稀释

C.患有肺部疾病

D.两个值之间的正常差别

E.二氧化碳监测仪出现差错

F.通气过度
