The American Fork Hospital Sleep Center offers a number of sleep studies and tests, each of which is useful for the treatment of various disorders and conditions. Each test is performed by registered sleep technicians and overseen by our board-certified sleep specialist physicians.

Diagnostic Overnight Sleep Study / Polysomnography (PSG):
General monitoring of the amount and level of sleep through analysis of brain waves, eye movement and a variety of body functions during sleep. This includes monitoring breathing patterns, blood oxygen levels, heart rhythms and limb movements.

Portable Home Monitoring Sleep Study:
Portable home monitoring is used as an alternative diagnostic test that it is less expensive and quicker to deploy than to in-laboratory overnight sleep studies. Portable home monitoring studies can be used with carefully selected patients who must be seen by a sleep specialist before participating in the study.

CPAP Follow Up Overnight Sleep Study / Titration Sleep Study:
Continuous Positive Airway Pressure (CPAP) treatment involves the delivery of air into the airway through a mask to normalize breathing and oxygen levels. A titration study allows us to find the best pressure for your continued treatment at home.

Therapeutic Bi-level Titration:
Bi-level titration provides two different pressures — a higher one during inhalation (IPAP) and a lower pressure during exhalation (EPAP) — delivered to the airway through a mask.

Split-night Polysomnography (PSG) with CPAP Titration:
Split-night PSG is conducted when moderate or severe sleep apnea is discovered or strongly suspected. The first 3-4 hour period of the night is diagnostic, and certain levels of sleep time and apnea or hypopnea must be met before the patient can be switched to the therapeutic study. The second half of the night (the therapeutic portion) is used to determine the necessary CPAP pressure required to alleviate apnea. This test does not always get a patient to the best CPAP level, so a follow-up titration study may be required. Because of the possible negative aspects of the test, sleep specialists prefer not to perform split studies, but some payers require them in certain situations.

Auto SV - Complex Central Sleep Apnea Titration:
Treatment for Central Sleep Apnea, Complex Sleep Apnea and Periodic Breathing with PAP therapy.

Multiple Sleep Latency Test (MSLT):
A diagnostic test performed during the daytime and used to diagnose narcolepsy and measure the degree of daytime sleepiness. An MSLT measures how quickly the patient falls asleep in quiet situations during the day, monitors how quickly and how often REM sleep occurs, and is usually performed following an overnight diagnostic PSG.

Maintenance of Wakefulness Test (MWT):
The MWT helps determine if a person is abnormally sleepy during the day by measuring his or her ability to stay awake. This is a standardized test frequently used to justify the level of alertness/wakefulness for employment reasons, particularly for commercial drivers and pilots.

PAP Nap:
This test is to address patient frustrations and anxieties about PAP therapy and improve therapy compliance. PAP naps are performed during the daytime and include some of the monitoring elements of overnight studies.

Sleep Apnea Screen:
A simple, cost-effective home sleep screening tool designed to identify patients at risk for sleep-disordered breathing. This portable device uses a nasal cannula and pressure transducer to measure apnea or hypopnea, airflow limitation, and snoring. This information can be used to convince a patient that he does more than simply snore during the night. This device is checked out by the patient and used at home. This test does not test positive in all patients with sleep apnea, therefore, an overnight sleep study may be required even if this test is normal.

WorkMed Sleep Evaluations:
These procedures focus on industrial and employment-related care, and can include parts of the other tests described above.

Mask Fitting and CPAP clinic:
American Fork Hospital Sleep Center patients with obstructive sleep apnea who use a CPAP mask and machine can use this service for help with finding the best-fitting CPAP mask. Each patient who has a CPAP titration study at the Sleep Center is entitled to one free mask fitting session.
