Home sleep testing

Apnox module

Home sleep testing (HST) ‒ autonomous data recording onto memory card

Elegant screening test allow detecting signs of OSA, self-administered by the patient at home. Can be supplemented with equipment for video monitoring.

The camera is synchronized with ApnOx during the preparation for the study. Video and audio data is saved onto the memory card.

It is possible to control the recorded data using the tablet with a downloaded application.

Laboratory-based sleep testing


Telemetric recording mode ‒ data transmission into computer via wireless Bluetooth channel

  • quality control of recorded signals and correctness of sensors attachment;
  • CPAP titration (therapeutic pressure selection);
  • synchronized registration of audio and video data;
  • marking the significant events.

The system contains equipment for video monitoring, it detects synchronous data streams stored in the PC memory under control of staff.


Videomonitoring kit

Videomonitoring Kit can be a part of a sales package for ApnOx-10 and ApnOx-04

Provides simultaneous recording, analysis and storage of PSG, video and audio data, including the option of preparing short video clips.

Specialized "Viewer" application allows viewing specified fragments of physiological parameters and video data on doctor's PC (onto CD/DVD discs or other storage devices) using main functions of visual analysis.
