Overview
Other tests for sleep apnea include EEG, EMG, EOG, ECG, a nasal airflow sensor, and a snore microphone.
Sleep Apnea Other Diagnostic Tests
A clinical practice guideline by the American College of Physicians[1] and the American Academy of Sleep Medicine[2][3] address diagnosis.
Other tests
- EEG (electroencephalogram) to measure and record brain wave activity
- EMG (electromyogram) to record muscle activity to determine REM stage sleep
- EOG (electro-oculogram) to record eye movements to determine REM stage sleep
- ECG (electrocardiogram) to record heart rate and rhythm.
- Nasal airflow sensor to record airflow
- Snore microphone to record snoring activity
Home respiratory polygraphy
Home respiratory polygraphy (HRP) or called home sleep apnea testing (HSAT), can be classified into:
- Level 2 (L2), which include airflow, EEG, EOG, EMG, ECG/HR, effort SaO2
- Level 3 (L3), which include airflow, thoracoabdominal bands, body position, electrocardiography, and oxygen saturation
- Level 4 (L4), which added oxygen saturation and maybe heart rate
Randomized controlled trials have compared the impact of using versus portable monitors that can be used at home:
- Corral found no significant difference.[4].
- Chai-Coetzer found no difference using L3 channels but inconclusive results with L4 monitoring (which just included oximetry and heart rate)[5].
- Whitelaw found no significant difference.[6]
