Examined in this study are the results of six tests of pulmonary function immediately preceding and following bronchial drainage in twenty-six patients with cystic fibrosis. Highly significant increases averaging 5.67, 4.13, 13.47, and 6.98 percent occurred in peak expiratory flow rate, forced vital capacity, expiratory reserve volume, and inspiratory capacity respectively. Significant increases in peak expiratory flow rate, forced vital capacity, and inspiratory capacity were observed in a subgroup of six of the above patients who had evidence of bronchospasm. The authors conclude that bronchial drainage will produce significant increases in routine pulmonary function values. The results suggest that this treatment is most effective in clearing the larger, more proximal, airways and is of benefit even in the presence of clinical bronchospasm.
本研究检测了26例囊性纤维化患者在支气管引流前后即刻的六项肺功能测试结果。呼气峰值流速、用力肺活量、呼气储备量和吸气量分别平均显著增加了5.67%、4.13%、13.47%和6.98%。在上述六名有支气管痉挛证据的患者亚组中，呼气峰值流速、用力肺活量和吸气量也有显著增加。作者得出结论，支气管引流将使常规肺功能值显著增加。结果表明，这种治疗方法在清除较大、更靠近近端的气道方面最为有效，即使在存在临床支气管痉挛的情况下也有益处。
