Sleep diagnostic services are provided 24 hours a day, 7 days a week at the Geisinger-Lewistown Hospital Sleep Center. Our Center provides private and secure home-like sleeping rooms with private restrooms with showers.
When you arrive for your sleep study you will report to the Emergency Department registration desk at your assigned time. The sleep center technician will meet you at the desk after you "check-in" at the desk.
An MWT is performed to determine the ability of the patient to stay awake. Many times this test is performed on commercial truck drivers and airline pilots.
The MWT consists of four, forty-minute trials, at two-hour intervals with the first trial 1 ½ to 3 hours after your morning awakening. You will be instructed to get dressed in your street clothes. You will not be permitted any caffeine after the first trial. Nicotine is avoided within 30 minutes prior to each trial. During each trial the room is kept at a comfortable temperature. The room is dimly lit with a 7-watt night-light. While sitting up right in a recliner, you will be instructed to resist falling asleep during the trial without singing, talking, slapping your face, bouncing legs, etc. in attempt to remain awake. After performing certain calibrations, each trial is started and you are instructed, "The test is starting, and please try and stay awake". You will not be permitted to nap between any of the trials.
