A sleep study is a procedure which involves sleeping overnight in comfortable surroundings at El Paso Sleep Center. During the study, you will have several types of wires and monitors attached to you. These wires and monitors will give us information about your sleep patterns and allow us to diagnose several types of sleep disorders. A technologist will monitor your sleep through the night. If your provider has ordered a Multiple Sleep Latency Test (MSLT) in addition to your overnight test, you will continue with your study up to 6:30pm.
