There are two components to a sleep study:



  • First, a diagnostic portion, where we will monitor your breathing, brain wave activity, heart rate, body movements and blood oxygen levels while you sleep.

  • Second – should your diagnostic test suggest sleep apnea – may be to apply CPAP (Constant Positive Airway Pressure) in the lab while you sleep. This “titration” study is to determine the best settings for CPAP therapy should you require it. NOTE: There are different methods of treatment available, depending on the type of sleep disorder you have.

Occasionally, both portions of the test are performed in one evening, but some patients require a second night for the titration study. If the results show that you would benefit from CPAP therapy, you will likely be scheduled for a return visit for the titration study.



What can I expect in an overnight sleep study?

What are the treatment options for sleep disorders?


The options depend on the type of sleep disorder that is diagnosed as a result of your sleep study. You and your physician will work together to determine what treatment is right for you. Common treatment options include:

  • CPAP (continuous positive airway pressure) – a CPAP delivers pressurized room air through a nasal mask to keep the airway open and prevent it from collapsing during sleep.

  • Dental – custom-made dental appliances reposition the lower jar and tongue, allowing the free flow of air.

  • Surgical – removal of tonsils, adenoids, nasal polyps and structural deformities.

  • Pharmaceutical – prescriptions to manage sleep disorders.

  • Sleep Hygiene – a sleep routine you follow every night to aid rest.

  • Health & Wellness – weight loss, exercise and nutritional counseling.

  • Behavioral Counseling – strategies to help you overcome a sleep disorder.
