Mucus hypersecretion and impaired mucus clearance are well-known symptoms in patients with chronic obstructive pulmonary disease and cystic fibrosis. These symptoms should not be considered as innocent but they deserve treatment. A well known therapy to improve mucus transport is chest physiotherapy. Forced expiratory manoeuvres are probably the most effective part of chest physiotherapy. Essential in the application of forced expiratory manoeuvres to improve mucus transport is whether airway compression should be used or prevented. The variables that influence the localization and degree of airway compression are expiratory force, lung volume and possibly mouth pressure. With these variables the patient should learn the most efficient form of forced expiration, according to the individual condition of the patient.
黏液分泌过多和黏液清除功能受损是慢性阻塞性肺疾病和囊性纤维化患者的常见症状。这些症状不应被视为无害，而是值得治疗。一种改善黏液运输的著名疗法是胸部物理治疗。用力呼气动作可能是胸部物理治疗中最有效的部分。在应用用力呼气动作来改善黏液运输时，关键在于是否应使用或防止气道受压。影响气道受压位置和程度的变量包括呼气力、肺容积，可能还有口腔压力。根据患者的个体情况，患者应利用这些变量学习最有效的用力呼气形式。
