Signals and parameters:

oxygen saturation (SpO2);
respiratory rate and conventional respiratory amplitude, as well as snore and airflow velocity (using pressure airflow sensor (P-flow);
pulse rate and perfusion index (based on photoplethysmogram using SpO2 sensor);
body position and total movement activity (integrated movement activity sensor);
CPAP Pressure.
Recording modes:

autonomous – data record onto the memory card;
telemetric – data transmission into computer via wireless Bluetooth© channel.
Over 10-hour record of physiological data onto the memory card.

As a result of the study, necessary reports on sleep statistics are generated based on automatically detected events.

Signals and parameters:

respiratory effort from thoracic and abdominal sensors;
electrocardiogram;
heart rate (based on ECG);
snore (accelerometer sensor);
airflow (thermistor airflow sensor);
pulse wave transit time and indirect assessment of the blood pressure dynamics (based on ECG and PPG);
motility (accelerometer sensors or surface EMG sensors);
skin conductance;
signals from DC-inputs.
