The Buteyko Breathing Technique (BBT) is promoted as a drug-free asthma therapy. It is based on the premise that raising blood PaCO2 through hypoventilation can treat asthma. Our study was designed to examine whether the Buteyko Breathing Technique, as taught by a video, is an efficacious asthma therapy. Thirty-six adult subjects with mild to moderate asthma were randomized to receive either a BBT or placebo video to watch at home twice per day for 4 weeks. Asthma-related quality of life, peak expiratory flow (PEF), symptoms, and asthma medication intake were assessed both before and after intervention. Our results demonstrated a significant improvement in quality of life among those assigned to the BBT compared with placebo (p = 0.043), as well as a significant reduction in inhaled bronchodilator intake (p = 0.008). We conclude that the BBT may be effective in improving the quality of life and reducing the intake of inhaled reliever medication in patients with asthma. These results warrant further investigation.
布泰科呼吸法（BBT）被宣传为一种无药物的哮喘治疗方法。它基于通过低通气提高血液中二氧化碳分压（PaCO2）可治疗哮喘这一前提。我们的研究旨在检验通过视频教授的布泰科呼吸法是否为一种有效的哮喘治疗方法。36名轻度至中度哮喘成年受试者被随机分为两组，一组接受布泰科呼吸法视频，另一组接受安慰剂视频，让他们在家中每天观看两次，持续4周。在干预前后评估与哮喘相关的生活质量、呼气峰值流速（PEF）、症状以及哮喘药物摄入量。我们的结果表明，与安慰剂组相比，接受布泰科呼吸法的受试者生活质量有显著改善（p = 0.043），吸入支气管扩张剂的摄入量也显著减少（p = 0.008）。我们得出结论，布泰科呼吸法可能对改善哮喘患者的生活质量和减少吸入缓解药物的摄入量有效。这些结果值得进一步研究。
