对哮喘病患儿进行肺功能监测.且以量化指标评估其病情,已渐为临床所重视。最大呼气流速率(PEFR)是一简单、实用的方法,但我国正常小儿PEFR值的资料甚少。本文报告对935例健康儿童的测定结果。 方法与结果 一、测试方法 选择身体健康、无心肺疾病的中小学生935人,男458人,女477人。8-9岁171人,-11岁500人,-13岁219人.-14岁45人。身高在110-170cm。测试前先给学生讲解测试方法,并示教练习,记录年龄、身高,小儿取立位,矫正PEFR仪指针置于零位,先令小儿口含吹嘴,紧闭双唇封闭吹嘴四周.让小儿深吸气后,立即以最大力量最快速度吹气,在1秒钟内将气体一次吹入峰流仪嘴内.连续吹气4次,每次间隔2分钟。记录读数,精确到刻度1O,取4次中的最大值作为该小儿PEFR最大呼气流速值。 二、检查结果935例测定结果见表。
The monitoring of pulmonary function in children with asthma, and quantitative indicators to assess their condition, has gradually become clinically important. The maximum expiratory flow rate (PEFR) is a simple and practical method, but there is little data on the PEFR of normal children in our country. This article reports the results of 935 healthy children. Methods and Results First, the test method to choose a healthy, non-heart disease of 935 primary and secondary students, 458 male and 477 female. 171 for 8-9 years, 500 for 11 years, 219 for -13 years and 45 for 14 years. Height 110-170cm. Test before the test method to explain to students and teach practice, record age, height, pediatric take stand, correction PEFR instrument pointer at zero, shill pediatric mouth with mouthpiece, closed lips closed mouthpiece around. Immediately after the child has taken a deep breath, he puffs the gas at the fastest speed with maximum force, and blows the gas into the peak flow mouth once in a second. Record the readings, accurate to the scale 1O, take the maximum of 4 times as the pediatric PEFR maximum expiratory flow rate value. Second, the test results 935 cases of test results shown in the table.
