Polysomnography refers to a systematic process used to collect physiologic parameters during sleep. A polysomnogram (PSG) is a procedure that utilizes electroencephalogram, electro-oculogram, electromyogram, electrocardiogram, and pulse oximetry, as well as airflow and respiratory effort, to evaluate for underlying causes of sleep disturbances. PSG is considered to be the gold standard for diagnosing sleep-related breathing disorders, which include obstructive sleep apnea (OSA), central sleep apnea, and sleep-related hypoventilation/hypoxia. PSG can also be utilized to evaluate for other sleep disorders, including nocturnal seizures, narcolepsy, periodic limb movement disorder, and rapid eye movement sleep behavior disorder. With recent technological developments, home sleep apnea testing can be done to confirm a diagnosis in patients with a high risk for moderate to severe OSA in the absence of comorbid medical conditions or other suspected sleep disorders.
多导睡眠图是指在睡眠期间用于收集生理参数的系统过程。多导睡眠图（PSG）是一种利用脑电图、眼电图、肌电图、心电图、脉搏血氧饱和度测定以及气流和呼吸努力来评估睡眠障碍潜在原因的程序。PSG被认为是诊断与睡眠相关呼吸障碍的金标准，这些障碍包括阻塞性睡眠呼吸暂停（OSA）、中枢性睡眠呼吸暂停以及与睡眠相关的通气不足/低氧血症。PSG还可用于评估其他睡眠障碍，包括夜间癫痫、发作性睡病、周期性肢体运动障碍和快速眼动睡眠行为障碍。随着最近的技术发展，在没有合并症或其他疑似睡眠障碍的情况下，对于中度至重度OSA高风险患者，可以进行家庭睡眠呼吸暂停测试以确诊。
