背景这项研究的目的是观察当受试者暴露在旋转的视动鼓中时，慢速深呼吸是否能防止胃电节律紊乱和晕动病症状的发生。方法46名年龄在17-26岁的健康男性和女性参加了这项研究，他们在转鼓中进行了预先测试，发现他们容易晕动病。他们被随机分成以下三种情况之一：缓慢深呼吸(n=18)、计数呼吸(受试者被要求每隔3分钟数一次呼吸，n=16)和对照组(受试者正常呼吸，n=12)。所有受试者在6分钟基线和16分钟轮换期间记录胃电。受试者每隔3分钟被问及他们的症状。结果三种情况下，从基线到旋转的心动过速百分率差异有统计学意义。在旋转过程中，计数呼吸组和对照组的胃过速百分比增加，但慢速深呼吸组的百分比保持不变。慢速深呼吸组(5.3)报告的症状明显少于数呼吸组(9.0)，但不是对照组(7.8)。结论：在以前被证明会引起胃过速的情况下，缓慢的深呼吸可以防止胃电节律紊乱的发展，并减少晕动病的症状。
BACKGROUND The purpose of this study was to see if slow deep breathing, a non-pharmacological procedure known to increase parasympathetic nervous system (PNS) activity, would prevent the development of gastric dysrhythmias and symptoms of motion sickness when subjects were exposed to a rotating optokinetic drum. METHODS Participating in this study were 46 healthy males and females aged 17-26 who were pre-tested in the rotating drum and found to be susceptible to motion sickness. They were randomly placed into one of the following three conditions: Slow Deep Breathing (n = 18), Counting Breaths (subjects were asked to count their breaths and asked for the count every 3 min, n = 16), and Control (subjects breathed normally, n = 12). Electrogastrograms were recorded from all subjects during a 6-min baseline and a 16-min rotation period. Subjects were asked about their symptoms every 3 min. RESULTS A significant difference in percent tachygastria from baseline to rotation was found between the three conditions. Percent tachygastria increased during rotation for the Counting Breaths group and the Control group, but remained the same as baseline for the Slow Deep Breathing group. The Slow Deep Breathing group (5.3) reported significantly fewer symptoms than the Counting Breaths group (9.0), but not the Control group (7.8). CONCLUSION In conclusion, slow deep breathing in a situation previously demonstrated to provoke tachygastria prevented the development of gastric dysrhythmias and decreased symptoms of motion sickness.
