Diagnostic principles

One of the advantages of this method is the possibility of performing the examination in outpatient care.  The diagnostic device records various measurements, registers the movements of the thorax and breathing movements, air flow through the nose and/or mouth, heart rate, determines the blood oxygen saturation and detects changes in body position.

In order to perform the recording of measurements, the patient is trained to connect the device at the clinic. At home, before bedtime, the patient connects the device and it switches on automatically, performing all the required measurements while the patient sleeps. In the morning, the patient disconnects the device. After the performance of measurements, the physician analyses the obtained data and provides an opinion.
