Asthma and chronic bronchitis are characterized by bronchial occlusion in expiration. Acute spasmodic asthma, if prolonged, may bring about changes in thoracic structure and diaphragm position which can result in permanent pulmonary inefficiency unless this tendency is corrected by breathing exercises. As expiratory obstruction becomes more chronic, irreversible emphysema develops. Thereafter therapy for bronchopulmonary insufficiency is necessary. The approaches to such therapy have been outlined and briefly evaluated, with emphasis upon the value of intermittent positive-pressure therapy.
哮喘和慢性支气管炎的特点是呼气时支气管阻塞。急性痉挛性哮喘若持续时间较长，可能会导致胸廓结构和膈肌位置发生变化，进而导致永久性肺功能不全，除非通过呼吸练习纠正这种趋势。随着呼气性梗阻变得更加慢性化，不可逆的肺气肿就会发展起来。此后，支气管肺功能不全的治疗就很有必要。本文已概述并简要评估了此类治疗方法，重点强调了间歇性正压疗法的价值。
