A polygraph measures the following signals

  • Breathing during sleep
  • Snoring – pathological or otherwise
  • Blood oxygen saturation – oxygen deficiency during sleep as stress for the body
  • Heart rate
  • ECG
  • Body position and movements

It can provide information about

  • Presence of sleep apnea syndrome and its severity


At the heart and lung practice, the patient is shown how to put on the device. The device is then worn on the body for the entire night. The patient sleeps at home in their own bed, not at a sleep laboratory. The device is then returned to the practice the following day before noon.
