我院自1978年起采用国产的~(133)氙生理盐水溶液和四探头综合功能测定仪,在动物实验的基础上,对正常人和一些呼吸道疾病患者进行~(133)氙分区动态的肺功能测定。现将20名健康献血员(男17名,女3名;年龄25～28岁)的肺功能测定结果作一初步报道。方法和结果将惰性气体~(133)氙溶于生理盐水,经静脉注射后,随血流到肺部,其中95％的~(133)氙由血液内逸到肺泡,再由肺泡经呼吸道排出体外.其排出的快慢和肺内浓度的变化,反映出肺部该处的血流相通气情况.~(133)氙放出的γ射线,通过自动记录仪在体外描记出~(133)氙变化的曲线,从描记曲线计算出
Our hospital from 1978 using domestic ~ (133) xenon physiological saline solution and the four probe integrated functional detector, based on animal experiments, normal and some respiratory disease patients with 133 (133) xenon partition dynamic lung Function determination. Now 20 healthy blood donors (17 males and 3 females; aged 25 to 28 years old) lung function test results for a preliminary report. Methods and Results Inert gas (133) xenon was dissolved in physiological saline. After intravenous injection, 95% of 133 Xenon was released from the blood to the alveoli and then to the alveoli via the respiratory tract In vitro, its rate of excretion and changes in lung concentration, reflecting the blood flow in the lungs where the ventilation situation. ~ (133) xenon emission of gamma rays, in vitro recorded by automatic recorder ~ (133) xenon changes The curve, calculated from the tracing curve
