Obstructive sleep apnoea (OSA) is at least twice more severe in the supine position compared with the non-supine positions in about three quarters of patients with OSA.1 About one-third of them even have ‘exclusively positional’ sleep apnoea with normal apnoea–hypopnoea index (AHI) in the non-supine positions, which makes them accessible to positional treatment (PT). Until recently, most PT devices were derived from the traditional ‘tennis ball technique’, which makes the supine position uncomfortable and stimulate patients to sleep on their side. There are plenty of such devices on the market, but they are by essence uncomfortable, and their long-term usage was reported to be very low.2 A new generation of ‘active’ PT was developed in recent years. It consists of small electronic devices worn either at the neck or at the chest level, which vibrate when the patients are in the supine position until they turn to their side. Several …

“良好的振动”：阻塞性睡眠呼吸暂停的体位治疗

在大约四分之三的 OSA 患者中，与非仰卧位相比，仰卧位的阻塞性睡眠呼吸暂停 (OSA) 至少严重两倍。 1 大约三分之一的患者甚至患有“完全体位性”睡眠呼吸暂停和正常呼吸暂停– 非仰卧位的低通气指数 (AHI)，这使他们可以进行体位治疗 (PT)。直到最近，大多数 PT 设备都源自传统的“网球技术”，这使得仰卧位不舒服并刺激患者侧睡。市场上有很多这样的设备，但它们本质上是不舒服的，据报道它们的长期使用率非常低。2 近年来开发了新一代“有源”PT。它由佩戴在颈部或胸部的小型电子设备组成，当患者处于仰卧位时，它会振动，直到他们转向一侧。一些 …
