In-lab Sleep Study (PSG)/ Titration
An in-lab sleep study, also known as a polysomnography (PSG), is a comprehensive test that measures your brain activity, eye movements, breathing, heart rate, oxygen levels, muscle tone, and body movements while you sleep. An in-lab sleep study is performed in a comfortable and private room at a sleep center, where you will be monitored by a trained technician throughout the night. An in-lab sleep study can diagnose various sleep disorders, such as obstructive sleep apnea, narcolepsy, periodic limb movement disorder, and REM sleep behavior disorder. An in-lab sleep study can also help evaluate the effectiveness of your treatment, such as CPAP therapy or oral appliances.
A technician will attach sensors to your head, chest, limbs, and finger, and monitor your sleep throughout the night. A PSG can determine whether you have sleep apnea or not by recording how often and how long you stop breathing during sleep. Sleep apnea is a condition where your breathing is interrupted repeatedly while you sleep, causing low oxygen levels and poor sleep quality. A PSG can also measure the severity of your sleep apnea by calculating your apnea-hypopnea index (AHI), which is the number of times you have apneas (complete pauses in breathing) or hypopneas (partial reductions in breathing) per hour of sleep. A higher AHI indicates a more severe sleep apnea.
A PSG can also diagnose other sleep disorders, such as narcolepsy, restless legs syndrome, and REM sleep behavior disorder, by analyzing your sleep stages and cycles, and detecting any abnormal patterns or behaviors during sleep1. A PSG can help your doctor find the best treatment for your sleep problem and improve your sleep health.
