If you’re having trouble sleeping, your doctor may recommend a sleep test. A sleep test is a test that records your sleep patterns and body functions while you’re sleeping.

The most common type of sleep test is polysomnography, which can diagnose a wide range of sleep complications.

A sleep test is typically conducted in a sleep laboratory. You will be asked to change into comfortable clothing and personal hygiene before technicians install the device.

These sensors will record your brain activity, heart rate, breathing, and oxygen levels while you sleep.

These sensors may include:
🔹 Electrocardiography (ECG): The sensor monitors the electrical activity in the heart.
🔹 Electroencephalography (EEG): The sensor monitors your brain wave patterns during sleep.
🔹 Electro-oculography (EOG): The sensor detects eye movement.
🔹 Electromyogram (EMG): The sensor tracks muscle movements while you sleep.
🔹 Respiratory inductive plethysmography (RIP) belt: A belt will be strapped around your chest and your abdomen to measure the expansion of your chest and abdomen while breathing.
