作者对哮喘儿童用激流吸入器(Turbuhaler)进行研究,以阐明在吸入前需呼出到残气容积(RV),吸入时头后仰和以后屏息的重要性。慢性或发作性哮喘患儿14(男10、女4)例,年龄8～14(平均11.6)岁。系双盲双标本交叉研究,每日相回时间每例接受4次不同形式的吸入:①头后仰,从 RV 深吸入至总肺活量时屏息10秒。②同①,但无屏息间歇.③头后仰从功能残气量(FRC)深吸入和吸入后屏息10秒。④从 FRC 深吸入,但头不后仰和无屏息间歇。4个
The authors studied asthma children with a Turbuhaler to elucidate the importance of breathing out to the residual volume (RV) before inhalation, head back-up and subsequent breath-hold when inhaled. 14 (10 males and 4 females) children with chronic or episodic asthma were aged 8 to 14 (mean, 11.6) years. Department of double-blind double-cross study, the daily phase-back time to accept each case 4 times different forms of inhalation: ① head back, deep breath from the RV to the total lung capacity breath-hold for 10 seconds. ② with ①, but no intermittent breath-holding. ③ head back from the functional residual capacity (FRC) deep inhalation and inhalation breath after 10 seconds. ④ deep inhalation from the FRC, but no head back and no breath-hold interval. 4
