本文收集110例因急性发病,具有典型症状和体征,拟诊为肺栓塞(PE)的住院病人,又经同位素肺灌注扫描和肺动脉造影等检查进一步证实。采用Enghoff 改良的 Bohr 法测定肺死腔气(V_D),在校正死腔值及每分钟通气(VE),潮气量(V_T)及呼吸商(R)后,计算出死腔气/潮气量(V_D/V_T)的比值。110例中,平均年龄为52.2±15.5岁。将受检者分为8组:第1组29例,肺灌注扫描和/或肺血管造
This article collected 110 cases of acute onset, with typical symptoms and signs, to be diagnosed as pulmonary embolism (PE) inpatients, but also by isotope lung perfusion scan and pulmonary angiography and other tests to further confirm. The modified Bohr method was used to measure the dead space gas (V_D). The dead space gas / tidal volume (V_D) was calculated after correcting for dead space and VE, V_T and respiratory quotient (R) V_D / V_T) ratio. In 110 cases, the average age was 52.2 ± 15.5 years. Subjects were divided into 8 groups: group 1, group 29, lung perfusion scan, and / or pulmonary angioplasty
