Sleep Apnea Testing and Diagnosis

Your doctor may make an evaluation based on your signs and symptoms or may refer you to a sleep disorder center. There, a sleep specialist can help you decide on your need for further evaluation. Such an evaluation often involves overnight monitoring of your breathing and other body functions during sleep. Home sleep testing is gaining in popularity because it's often easier for you and less expensive. Tests to detect sleep apnea may include:

If you have obstructive sleep apnea, your doctor may refer you to an ear, nose, and throat doctor (otolaryngologist) to rule out any blockage in your nose or throat. An evaluation by a heart doctor (cardiologist) or a doctor who specializes in the nervous system (neurologist) may be necessary to look for causes of central sleep apnea.
