A sleep study is generally done on an outpatient basis at night. Procedures may vary based on your condition and your healthcare provider's practices.
-
You will need to remove any jewelry or other objects that may interfere with the procedure.
-
You will change into pajamas or a hospital gown.
-
The healthcare team will put small metal discs (electrodes) on your head and body for EEG, ECG, EOG, and EMG cables.
-
The team will put a small clip on your finger to measure the oxygen level (pulse oximetry) in your blood. The team will also check your breathing.
-
The temperature of the room may need to be kept at a certain level, but blankets can be added or removed as needed.
-
Lights will be turned off and monitoring will start before you fall asleep.
-
For multiple sleep latency testing (MSLT), short naps will be assigned at intervals.
-
For multiple wake testing (MWT), you will be asked to try to stay awake for certain periods.
-
When the study is done, the electrodes and other devices will be removed.
