目的：探讨静脉注射常规剂量氨茶碱对正常中老年人运动肺功能的影响。方法：１４例正常中老年人分别于静脉注射０．２５ｇ氨茶碱前后，作症状限制性运动肺功能检查。运动负荷递增采用斜坡法，每分钟增加１０Ｗ。电脑自动连续记录被检者静息与运动时的呼吸参数、运动负荷、血氧饱和度及心率等。结果：氨茶碱能显著增加静息时分时通气量、呼吸频率及心率，但对运动能力和最大运动负荷时的分时通气量、氧耗量和通气方式等均不产生明显的影响。结论：静脉注射常规剂量氨茶碱对正常中老年人运动能力和氧耗量无明显影响
Objective: To investigate the effect of intravenous injection of conventional dose aminophylline on exercise-induced pulmonary function in middle-aged and elderly people. Methods: 14 cases of normal middle-aged and elderly people before and after intravenous injection of 0.25g aminophylline, as a symptom of restrictive exercise pulmonary function test. Increasing exercise load using the ramp method, an increase of 10W per minute. The computer automatically and continuously recorded the subjects were resting and exercise breathing parameters, exercise load, oxygen saturation and heart rate. Results: Aminophylline significantly increased resting time-division ventilation, respiratory rate and heart rate, but had no significant effect on exercise capacity, time-division ventilation at maximum exercise load, oxygen consumption and ventilation. Conclusion: The intravenous injection of conventional dose of aminophylline has no significant effect on exercise capacity and oxygen consumption of middle-aged and elderly people
