Abstract

Periodic limb movements (PLMs) during sleep are involuntary phenomena characterized by periodic episodes of repetitive, stereotypical movements of the limbs. PLMs are a common finding in sleep studies, but these movements are rarely perceived by the patient and do not typically cause specific symptoms.

During sleep studies, an increase in respiratory flow can be observed for 1–2 breaths corresponding to the PLMs, as detected by nasal cannula or, more rarely, by thoraco-abdominal belts. It has been hypothesized that these brief increases in ventilation may cause difficulties in interpreting respiratory events, as they alter the breathing pattern.

Non-invasive ventilation in spontaneous/assisted mode is commonly used during sleep in many chronic respiratory diseases characterized by hypercapnic respiratory failure. Patient-ventilator synchronization depends on the ventilator's algorithm and the patient's breathing pattern.

We present some polysomnographic images that suggest a potential pathogenic role of PLMs in patient-ventilator asynchrony.

患者-呼吸机不同步和周期性肢体运动：可能的联系？

睡眠中的周期性肢体运动（PLMs）是一种不自觉的现象，其特征是肢体的周期性重复、刻板运动。睡动在睡眠研究中是一个常见的发现，但这些运动很少被患者察觉，通常不会引起特定的症状。在睡眠研究中，通过鼻插管或更罕见的胸腹带检测，可以观察到与PLMs相对应的1-2次呼吸流量增加。据推测，这些短暂的通气增加可能会导致解释呼吸事件的困难，因为它们改变了呼吸模式。在许多以高碳酸血症性呼吸衰竭为特征的慢性呼吸系统疾病中，通常在睡眠期间采用自发/辅助模式的无创通气。患者与呼吸机的同步取决于呼吸机的算法和患者的呼吸模式。我们提出了一些多导睡眠图图像，提示PLMs在患者-呼吸机不同步中的潜在致病作用。

期刊介绍： Sleep Medicine aims to be a journal no one involved in clinical sleep medicine can do without. A journal primarily focussing on the human aspects of sleep, integrating the various disciplines that are involved in sleep medicine: neurology, clinical neurophysiology, internal medicine (particularly pulmonology and cardiology), psychology, psychiatry, sleep technology, pediatrics, neurosurgery, otorhinolaryngology, and dentistry. The journal publishes the following types of articles: Reviews (also intended as a way to bridge the gap between basic sleep research and clinical relevance); Original Research Articles; Full-length articles; Brief communications; Controversies; Case reports; Letters to the Editor; Journal search and commentaries; Book reviews; Meeting announcements; Listing of relevant organisations plus web sites.
