an overnight test that measures brain waves, heart rate, breathing patterns, blood oxygen, and body movements
a series of recordings of measurements taken while you sleep
a sleep study designed to find abnormalities of sleep
a sleep study in which measurements are used to identify different sleep stages and classify various sleep problems
a sleep study that involves using electroencephalography (EEG) to monitor the brain and muscle activity, heart rhythm, and breathing during sleep
a test which measures bodily functions during sleep
poly-sawm'na-gram; PSG Multi-channel graph recorded during sleep. Generally includes electro-encephalogram (EEG), electro-cardiogram (ECG or EKG), electro-myogram (EMG), electro-oculogram (EOG), flow, thoracic effort, abdominal effort, oxyhemoglobin saturation (SaO2). Term: Description: .
Procedure to monitor patient's sleeping patterns, typically in a sleep studies centre or laboratory. Brain waves, oxygen levels, respiratory effort, snoring, heart rate, heart rhythm and muscular activity are monitored and recorded.
A test where a patient sleeps while having his or her EEG, EKG, EMG, oxygen saturation, and respiration monitored and recorded. It is usually noninvasive and extremely safe. The most uncomfortable part is the scrubbing in order to prepare areas of the head for EEG and EMG monitoring.
also called a PSG, sleep study, or sleep test; a non-invasive test that records vital signs and physiology during a night of sleep. It includes measurements from an EEG, EMG, and EOG, as well as respiratory airflow, blood oxygen saturation, pulse rate, heart rate, body position, and respiratory effort.
a sleep study consisting of measurements of electrical activity in the brain, eyes, muscles, heart in addition to measurements of breathing and oxygen.
A sleep study that continuously measures and records a person's physiological activity during a normal sleep period.
a type of sleep study; a written record of a person's sleep using a number of measures. From the Latin and Greek words. "poly" meaning "many," "somno" meaning "sleep," "gram" meaning "written."
Procedure to monitor patient's sleeping patterns, typically in a sleep lab. Aspects monitored include brain waves and stages of sleep, oxygen, respiratory effort, snoring, heart rate and rhythm, and muscular activity.
continuous and simultaneous recording of physiological variables during sleep, i.e., EEG, EOG, EMG (the three basic stage scoring parameters), EKG, respiratory air flow, respiratory excursion, lower limb movement, and other electrophysiological variables. See polysomnograms.
A continuous and simultaneous recording of multiple physiological variables during sleep.
PSG] Polysomnogram (PSG) is a test used to diagnose sleep apnea. During the polysomnogram test, a variety of body functions, such as the electrical activity of the brain, eye movements, muscle activity, heart rate, respiratory effort, air flow, and blood oxygen levels are recorded at night during sleep.
An overnight polysomnogram (or Psg) is an observation and recording of a patient of a minimum of 6 hours while he or she sleeps. It is usually carried out by a polysomnographic technician. The patient has electrodes applied to them in various places so that leg movements, heart rhythm, O2 stats, body position, flow as well as chest and abdomen effort, and stages of sleep may be determined or measured and recorded.
