While it is possible to use questionnaires and visual evaluation to screen for suspected obstructive sleep apnea (OSA), the primary method for diagnosing OSA at present is to have the patient undergo an overnight sleep study, known as polysomnography (PSG). This study measures and records a number of different physiologic variables during sleep such as airflow, oxygen levels, brain activity and respiratory effort.
Once diagnosed, several treatment options exist for dealing with OSA:
These include lifestyle changes such as an exercise and weight-loss regiment, medical intervention such as the addition of a sleeping device or a dental orthotic which can help to create long-term, healthy sleeping patterns. Nasal CPAP (continuous positive air pressure), CPAP or surgery.
The diagnostic polysomnographic studies (PSG) must be read by certified sleep physicians and most commonly provided in an overnight sleep lab. We are happy to provide, by request, the names of sleep physicians and sleep labs with whom we work.
