Obligatory medical device diagnostics.
- Cardiorespiratory polygraphy (performed on an outpatient basis) – if nocturnal breathing disorder is suspected.
- Nocturnal oximetry (oxygen measurement), performed on an outpatient basis.
- Polysomnography (sleep laboratory; measurement of various body functions during sleep that provide information about sleep quality) – in which the following parameters are monitored:
- Encephalogram (EEG; recording the electrical activity of the brain).
- Electrooculography (EOG; method of measuring the movement of the eyes or changes in the resting potential of the retina).
- Electromyography (EMG; measurement of electrical muscle activity).
- Heart rate
- Blood oxygen saturation (SpO2) by pulse oximetry (method for non-invasive determination of arterial oxygen saturation via measurement of light absorption)+.
Often an ambulatory respiratory polygraphy is sufficient to confirm OSA; this is a device that records breathing, snoring sounds, heartbeat, body position, movements and oxygen levels in the blood during sleep[10 events or more per hour of sleep time is considered sleep apnea; a single event must be at least 10 seconds long]
Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification or to exclude complications.
