1. Do you have trouble sleeping 3 or more nights per week?

If you answered “yes” to any of these questions, you may have a sleep disorder and you should call a Houston sleep disorder specialist to schedule a sleep lab at 281-341-3000.
Three types of in-lab sleep studies
A Polysomnogram (PSG), is a common overnight sleep test for patients with sleep disorders. A PSG monitors many body functions such as respiratory airflow, brain activity, muscle activity, eye movements and heart rate during sleep. After arriving for a PSG, a sleep technician will explain the process and then answer any questions the patient may have. Sensors will then be attached to the patient. The patient may go to sleep immediately or can relax for a while by reading or watching television. The patient will be able to get up at any time throughout the night to get comfortable or to go to the bathroom. In the morning, the sensors are removed and the patient is free to go home.
A Multiple sleep latency test (MSLT) is a sleep study test performed throughout the day to measure how tired a person is or to see if breathing treatments are working. MSLT’s are usually performed after a Polysomnogram and record if the patient falls asleep during the test, and if so, which stages of sleep they enter.
A Maintenance of Wakefulness Test (MWT) is also a daytime study test which measures wakefulness and alertness. Many employers will require employees to take a MWT if they have been diagnosed with a sleep disorder. During an MWT a patient lies comfortably on a bed and tries to stay awake as long as possible. These MWTs generally start 1.5 to 3 hours after waking and consist of several trials with 2 hours in between each session. Sensors placed on the head, face, and chin determine if the patient falls asleep. The test will end if the patient does not fall asleep after 40 minutes.

How to prepare for a sleep study
Most sleep technicians want their patients to stick to their normal nightly routine in order to get the most accurate results. A recommended treatment plan can only be achieved if there is an accurate assessment of the ordinary sleep pattern. However, there are a few things to do in preparation for a Houston Sleep Study.
• Please notify the office in advance if any special needs are required (i.e. use of a wheelchair, same gender preference of sleep technician or the need of oxygen at night)
• Bring completed paperwork as well as identification and insurance information
• Bring comfortable clothes to sleep in as well as a change of clothes for the following morning
• Arrive shortly before usual bedtime, generally 8 pm to 9 pm for an overnight study
• Bring all medications. Staff members cannot administer or obtain medications
• Eat dinner before arrival for sleep study
What happens after a sleep study
After a polysomnogram, the sleep technologist will chart the wake-sleep times as well as the body movements and brain function. The interpretation and any recommendations will be sent to the referring physician or specialist. If the physician recommends a follow up MSLT or MWT sleep study, those can be scheduled by calling 281-341-3000.
