Polysomnography is an overnight sleep test done to patients suspected to have Obstructive sleep apnea and other sleep-related disorders like central sleep apneas, narcolepsy, periodic limb movement disorders etc.

This test is conducted in a sleep laboratory which is well equipped with a monitor and sleep machine. Patient has to sleep overnight in the laboratory. Electrodes are applied to the head to monitor the electrical activity of the brain. A thin plastic tube (pressure transducer) is tied around the nose to monitor the flow. Bands are applied to the chest and abdomen to check the respiratory movements. A tiny probe is attached to the finger to monitor the oxygen level of the blood throughout the night. All these bands, probes and sensors are attached to a monitor from where we can actively monitor and records all the parameters. Analysis of the recorded parameters helps in making or excluding a diagnosis of sleep apnea.
