Sleep Disorders

Understand the Benefits of Diagnostic Sleep Tests

To help you or your loved one sleep better and feel more rested, Riverside’s sleep specialists first need to understand why you are not sleeping well. Diagnostic services will determine if your sleep issues are the result of respiratory or neurological concerns. A sleep study may be conducted to measure how much and how well you sleep and how alert you are during the daytime. 

A diagnostic sleep test helps our Riverside team diagnose potential common sleep disorders, assess their severity and develop a treatment plan for you. After asking questions about your sleep habits and daytime alertness, your physician may refer you to a Riverside sleep medicine center for a sleep study. A diagnostic sleep test is an essential step in determining and correcting sleep issues that can significantly affect your health and well-being.

Types of Sleep Studies Available at Riverside

Riverside offers various diagnostic sleep tests, also called sleep studies, to determine your current sleep level and treat your specific sleep issues. These non-invasive exams provide conclusive evidence of brain and bodily activity for optimal diagnostics. You may participate in one or more of the following types of sleep studies at Riverside:

  • Overnight sleep study: Polysomnogram, or PSG, is a study where you sleep overnight at one of our sleep centers while functions such as eye movement and brain activity are monitored.
  • CPAP titration: Continuous positive airway pressure (CPAP) is a treatment for sleep apnea. A CPAP titration study is used to determine the right air pressure for CPAP therapy in patients with sleep apnea.
  • Multiple sleep latency test: MSLT measures how quickly you fall asleep and enter REM sleep during quiet daytime situations.
  • Maintenance of wakefulness test: MWT measures your daytime alertness and ability to stay awake during daytime hours.
  • Home-based sleep apnea test: With a home-based portable monitor, this test allows you to conduct a sleep test at home.
  • Split-night sleep study: If sleep apnea is strongly suspected, a split-night sleep study can help determine if you have sleep apnea in the first half of the study and CPAP titration in the second half.

Monitors Provide Important Sleep Study Data

Depending on the type of study you have, monitors will be placed on your body to measure your sleep and body reactions. Some of the following monitors may be used during your Riverside sleep study:

  • EEG or electroencephalogram to measure brain wave activity
  • EMG or electromyogram to record muscle activity such as facial twitches, teeth grinding and leg movement
  • EOG or electrooculogram to record eye movement to help track the different stages of sleep
  • EKG or electrocardiogram to measure heart activities
  • Nasal airflow sensors, placed around the mouth and nose, to record breath temperature and airflow
