Sleep disordered breathing can be diagnosed with overnight polysomnography or sleep study.

It is a non-invasive overnight examination which monitors thoracic and abdominal respiratory efforts, nasal flow, ECG, EEG, oxygen saturation and body movements throughout the sleep.

After analysis of data collected, sleep specialist can give a diagnosis of the type of sleep disordered breathing and guide treatment.
Moderate to severe severity of OSA can be treated with CPAP (Continuous positive Airway Pressure) device.
