Abstract
Symptoms, clinical findings and pulmonary function in 47 patients with tracheobronchomalacia were compared with the bronchoscopic finding. The main symptoms were phlegm, cough and dyspnea. Recurrent respiratory infections and hemoptysis were features of the recent medical history. Only 30% had emphysema, and cor pulmonale in the ECG was uncommon. A notch in FEV1 [forced expiratory volume in 1 s] was seen in 25 patients (54%), against 3 (6%) in the controls. FVC [forced vital capacity], FEV1/FIV1 [forced inspiratory volume in 1 s] and notch in FEV1 were directly proportionate to the severity of the malacia. A low FEV1/FIV1 and notch in FEV1 are suggestive of tracheobronchomalacia and an indication for bronchoscopy.
