In 28 patients PO2 and PCO2 were measured continuously during diagnostic fiberbronchoscopy by means of transcutaneous electrodes (PtcO2 and Ptc CO2 System TCM Radiometer Copenhagen). A mean decrease in PtcO2 of 31% (s +/- 16.5%) was found. This effect can be prohibited by using oxygen insufflation at a rate of 0.5 liters per minute by nasal tube. The positive effect of fiberbronchoscopic lavage in cases of severe dyscrinism is documented. A mean increase in PtcO2 of 42% was found after the procedure, but there is a time lag of 20-30 minutes until the maximal increase is reached. In patients with known but not acute bronchial asthma the irritation of the bronchial system by fiberbronchoscopy induces a histamine release. There is no relation between the release of histamine and the decrease in arterial oxygen tension.
在28例患者中，通过经皮电极（PtcO2和Ptc CO2系统，丹麦哥本哈根TCM Radiometer公司）在诊断性纤维支气管镜检查期间连续测量PO2和PCO2。发现PtcO2平均下降31%（标准差±16.5%）。通过鼻导管以每分钟0.5升的速率吹入氧气可防止这种效应。记录了纤维支气管镜灌洗在严重分泌失调病例中的积极作用。术后发现PtcO2平均升高42%，但直到达到最大升高有20 - 30分钟的时间延迟。在已知患有非急性支气管哮喘的患者中，纤维支气管镜检查对支气管系统的刺激会诱导组胺释放。组胺释放与动脉血氧张力降低之间没有关系。
