What are some equipments used for sleep apnea test?

ANSWER

  • EEG (electroencephalogram) to measure and record brain wave activity.
  • EMG (electromyogram) to record muscle activity such as face twitches, teeth grinding, and leg movements, and to determine the presence of REM stage sleep. During REM sleep, intense dreams often occur as the brain undergoes heightened activity.
  • EOG (electro-oculogram) to record eye movements. These movements are important in determining the different sleep stages, particularly REM stage sleep.
  • ECG (electrocardiogram) to record heart rate and rhythm.
  • Nasal airflow sensor to record airflow.
  • Snore microphone to record snoring activity.
