Pulmonary function testing (PFT) in patients with tracheostomies has been perceived as difficult to perform and clinically unreliable. We studied the feasibility, quality, repeatability and clinical significance of PFT.
Patients with tracheostomies that underwent PFT from January 1, 2010 to February 29, 2012 were identified. Clinical history and PFT data were reviewed retrospectively.
Fifty patients (88% men) were identified. Forty-seven (94%) patients were able to perform PFT. Acceptable repeatability was obtained for FVC in 39 (83%) and for FEV1 in 41 (87%). Patients with tracheostomies showed difficulty in meeting ATS end-of-test criteria; only 9 (19%) met plateau criteria and 25 (53%) had exhalation times of greater than 6 s. Obstructive pattern was observed in 30 (64%) and restrictive pattern in 9 (19%). DLCO measurements were attempted in 43 patients and satisfactorily obtained in 34 (79%).
PFT can be performed with reliability in patients with tracheostomies, and they are useful for detecting and classifying types of lung dysfunction.
气管切开患者的肺功能测试（PFT）被认为操作困难且临床可靠性差。我们研究了PFT的可行性、质量、可重复性及临床意义。
确定2010年1月1日至2012年2月29日期间接受PFT的气管切开患者。回顾临床病史和PFT数据。
共确定50例患者（88%为男性）。47例（94%）患者能够完成PFT。39例（83%）患者的用力肺活量（FVC）和41例（87%）患者的1秒用力呼气容积（FEV1）获得了可接受的可重复性。气管切开患者在达到美国胸科学会（ATS）测试结束标准方面存在困难；只有9例（19%）达到平台期标准，25例（53%）呼气时间超过6秒。30例（64%）观察到阻塞性模式，9例（19%）观察到限制性模式。43例患者尝试进行一氧化碳弥散量（DLCO）测量，34例（79%）获得满意结果。
气管切开患者可可靠地进行PFT，这对于检测和分类肺功能障碍类型很有用。
