The authors have examined the pH, the pCO2, the pO2, and the oxygen saturation of the blood of patients upon whom endonasal surgery followed by tamponing of the nose had been performed. The gas values were examined on the second postoperative day and two days after the tampons had been removed. It was found that the blood pH remained within normal limits, whereas during the acute obstruction the pO2 values were diminished, the pCO2 values were increased, and the oxygen saturation of the blood was noticeably diminished. The authors recommend carefulness if the noses of patients with cardiorespiratory insufficiency are to be tamponed.
作者对接受鼻内手术并随后进行鼻腔填塞的患者的血液pH值、二氧化碳分压（pCO2）、氧分压（pO2）和血氧饱和度进行了检测。在术后第二天以及取出填塞物两天后对气体值进行了检测。结果发现，血液pH值保持在正常范围内，而在急性鼻塞期间，pO2值降低，pCO2值升高，血液的氧饱和度明显降低。作者建议，如果要对患有心肺功能不全的患者的鼻腔进行填塞，需谨慎操作。
