Chronic airway obstruction usually has an insidious onset. It is often difficult to diagnose unless the patient is examined by a physician familiar with the problem and causes. Potential causes can be divided into infectious, inflammatory, traumatic, and neoplastic. Although the precise incidence of each category is unknown, trauma, secondary to previous prolonged intubation for mechanical ventilation, is currently the most common premorbid factor.
慢性气道阻塞通常起病隐匿。除非由熟悉该问题及病因的医生对患者进行检查，否则往往难以诊断。潜在病因可分为感染性、炎症性、创伤性和肿瘤性。虽然每类病因的确切发生率尚不清楚，但继发于既往长期机械通气插管的创伤是目前最常见的病前因素。
