改良式腹式呼吸法促進慢性阻塞性肺疾病患肺功能與活動能力之效果

The Effect of Modified Abdominal Breathing on Promoting Pulmonary Function and Activity in COPD Patients

本研究訓練25位Gold stage I~II之COPD患者改良式腹式呼吸法，令其每日三次，每次100次呼吸，每月追蹤其肺功能及六分鐘行走距離共12個月。結果顯示短期的改良式腹式呼吸對肺功能並未能產生具統計意義之變化，但長期執行改良式腹式呼吸練習時，可使肺活量明顯增加，尤其在GOLD stage II的個案更為明顯；在活動能力方面，六分鐘行走距離先降後增，但走路後血氧飽合值降低值及疲倦指數均略為降低，雖改變量不具統計意義，均顯示出個案活動能力的維持效果。改良式腹式呼吸訓練雖然不像劇烈的運動訓練之以最大運動量訓練達提升心肺適能的效果，但是在肺功能與活動能力上即能達到維持或些微促進之效果。長期個案追蹤所顯示之改良式腹式呼吸對居家COPD病人肺功能的保健效果，值得醫護相關人員的參考。

Twenty-five GOLD stage I~II COPD subjects were recruited from OPD to received modified abdominal breath (MAB) training. They were requested to conduct MAB 3 times a day and 100 breaths each time during the study period. They received spirometry measurement and six-minute walking test monthly at the clinic. The follow up time was 12 months. The results indicated that short-term of practicing MAB did not make significant change in spirometric measures and distance of six-minute walking (6MWD). However, long-term MAB practice did make significant improvement in vital capacity (VC), especially in GOLD stage II subjects. The 6MWD the SPO2 and Borg RPE readings were not changed significantly during the follow-up period, either. These indicated a maintenance effect of MAB in activity capability. Modified abdominal breathing did not have the effect in improving maximal workload as high intensity exercise training did. However, modified abdominal breathing protected pulmonary functions and activity capability from deterioration. Being an equipment-free and easy to conduct at home, modified abdominal breathing is an effective alternative for COPD patients to conduct at home for rehabilitative purpose.
