what is sleep study
An all-night sleep study (also known as an all-night polysomnogram) allows Sleep Providers to measure how much and how well you sleep. Small electrodes are attached to your skin with small stick pads. They record and measure your breathing patterns, blood oxygen levels, muscle activity and heart rhythm.
Sleep studies are usually performed at night but can be performed during the day to accommodate shift workers. Polysomnography is performed to help diagnose sleep apnea, periodic limb movements, parasomnias and other disorders that disrupt sleep.
