In our institutions we routinely do posttracheostomy sleep studies on patients being treated for obstructive sleep apnea. We have identified several patients who failed to show objective evidence of improvement after tracheostomy. From our studies we have found that both mechanical obstruction and concomitant respiratory control dysfunction caused this failure. A unique tracheostomy tube was constructed to treat the subset of patients with internal collapse of the tracheostomy tube.
在我们的机构中，我们通常会对接受阻塞性睡眠呼吸暂停治疗的患者进行气管造口术后睡眠研究。我们已经确定了几名患者，他们在气管造口术后未能显示出客观的改善证据。从我们的研究中我们发现，机械性阻塞和伴随的呼吸控制功能障碍导致了这种失败。我们制造了一种独特的气管造口管来治疗气管造口管内部塌陷的患者亚组。
