Abstract

Circadian rhythms in lung resistance (R1) and dynamic compliance (C1dyn) of 7 healthy children (6 to 10 years) were validated (p less than .05) and then quantified (cosinor method); subjects' synchronization: light on at 0700; light off at 2100. Measurements were performed at fixed per hours (0730, 1130, 1630 and 2230) before and after the inhalation of a beta sympathomimetic bronchodilatator: minus 2mg orciprenaline. The measurements carried out after orciprenaline inhalation show a flattening of the curves, both circadian rhythms in R1 and C1 dyn are not detected (p greater than .05).

摘要

对7名健康儿童(6至10岁)的肺阻力(R1)和动态顺应性(C1dyn)的昼夜节律进行了验证(p小于0.05),然后进行了量化(余弦分析法);受试者的同步情况:07:00开灯;21:00关灯。在吸入β-拟交感神经支气管扩张剂(-2mg奥西那林)前后,于固定的每小时(07:30、11:30、16:30和22:30)进行测量。吸入奥西那林后进行的测量显示曲线变平,R1和C1dyn的昼夜节律均未检测到(p大于0.05)。
