Diagnostic Tests

Continuous Positive Air Pressure (CPAP)

Patients wear a mask over the nose and mouth during sleep. Constant and continuous air pressure is blown through air passages to prevent tissues from collapsing and blocking airways. Dental appliances may be needed to keep the tongue or jaw in a more forward position.

CPAP studies should be performed for patients already prescribed CPAP and who have experienced: 

  • Weight gain 
  • Weight loss 
  • Period of two or more years without evaluation or the return of symptoms, headaches, or hypersomnulence
