About our Pre-Payment Plan for Sleep Diagnostics

Sleep studies allow doctors to measure how much and how well you sleep. They also help show whether you have sleep problems and how severe they are. Sleep studies are important because untreated sleep disorders can increase your risk for high blood pressure, heart attack, stroke, and other medical conditions.

The Tucson Medical Center Sleep Diagnostic Lab can help patients get to the root of their sleeping problems utilizing state-of-the-art equipment and a staff of registered sleep technologists and board-certified physicians to ensure the highest quality of sleep evaluation.

We perform nighttime sleep studies for adults and children as well as daytime studies for nightshift workers. We are the only facility in Tucson performing studies on children as young as 1 month of age.

Sleep studies can help doctors diagnose:

  • Sleep-related breathing disorders (such as sleep apnea)
  • Sleep-related seizure disorders
  • Parasomnias (such as sleepwaking)
  • Narcolepsy
  • Insomnia
  • Circadian rhythm disorders

Packages, including physician interpretation, are available for the following sleep studies (Please note: the results will not be available at the time of the test. All tests are interpreted following the test with results forwarded to the referring physician):

MWT (maintenance of wakefulness test)

An MWT measures your ability to stay awake. Results may be used to show whether your inability to stay awake is a public or personal safety concern or to assess your response to treatment.

Overnight Sleep Study (polysomnogram)

A PSG records brain activity, eye movements, heart rate and blood pressure. It also records the amount of oxygen in your blood, how much air is moving through your nose and mouth while you breathe, and chest movements that show whether you're making an effort to breathe. In some cases, breathing sounds, including snoring, also are recorded.

Rate includes CPAP treatment if recommended.

Overnight Sleep with Treatment Study

A PSG with treatment records brain activity, eye movements and heart rate. It also records the amount of oxygen in your blood, how much air is moving through your nose and mouth while you breathe, and chest movements that show whether you're making an effort to breathe. In some cases, breathing sounds, including snoring, also are recorded. The first half of the study will be diagnostic (without treatment) and the last half would be with therapy if the patient meets a certain severity criteria. Possible therapy considerations would be CPAP (continuous positive airway pressure), BIPAP (bi-level positive airway pressure) and oxygen therapy. These therapies are used to treat various types of breathing disruptions during sleep.

Multiple Sleep Latency Test

An MSLT measures how sleepy you are and the speed of falling asleep. Patients are given several opportunities to fall asleep during the course of a day when they would normally be awake. For each opportunity referred to as a “nap,” time-to-sleep onset and the deepest stage of sleep are measured. People without sleep problems usually take an average of 10 to 20 minutes to fall asleep. Individuals who fall asleep in less than 5 minutes are considered to have some disruption of their nocturnal sleep regimen. Common sleep disorders this test is used for include narcolepsy, excessive daytime sleepiness, as well as assessing the effectiveness following therapeutic intervention as in CPAP or BIPAP therapy for sleep apnea.


This is used to help diagnose the presence and type of seizure disorders, to look for causes of confusion, and to evaluate head injuries, tumors, infections, degenerative diseases and metabolic disturbances that affect the brain. It is also used to evaluate sleep disorders and to investigate periods of unconsciousness. You will need to wash your hair the night before the test. Do not use any oils, sprays, gel or conditioner on your hair before this test.

CPAP/BIPAP Mask Fitting Class

CPAP or BIPAP is the most common and effective treatment for sleep apnea. The patient wears a mask over the nose during sleep, and pressure from an air blower forces room air through the nasal passages to keep the throat from collapsing. This therapy resembles that of a humidifier as it pushes room air over water.

The air can be either cool or heated depending on the patient’s comfort. Getting adjusted to the equipment and educated on how to fit the mask at home is sometimes necessary. Some patients have problems with their current mask (interface) and would like to try out different ones. Compliance is key to effective treatment, and comfort plays a role in compliance. This class educates patients on their new or existing therapies and helps answer any questions they may have.
