Lung hyperinflation is a typical clinical feature of patients with COPD. Given the association between breathing at elevated lung volumes and the manifestation of severe debilitating symptoms, therapeutic interventions such as positive expiratory pressure (PEP) therapy and its variations (temporary, oscillatory) have been devised to mitigate lung hyperinflation. However, the efficacy of these interventions remains to be conclusively demonstrated.

呼气正压治疗对慢性阻塞性肺病患者过度充气的影响。


肺过度充气是COPD患者的典型临床特征。鉴于肺容量增加的呼吸与严重衰弱症状的表现之间的关联，已经设计了呼气正压（PEP）疗法及其变体（暂时的、振荡的）等治疗干预措施来减轻肺部过度充气。然而，这些干预措施的有效性仍有待最终证明。
