The Snap Model 9 device is a wearable at home sleep recorder intended to record airflow, breathing effort and body position and is indicated for use and an aid for diagnostic evaluation of patient for sleep apnea and snoring.
A battery-powered device assembly intended to continuously measure and record patient physiological parameters (e.g., arterial oxygen saturation level, pulse rate, respiration effort/pattern, airflow waveform) during sleep in the home, to facilitate the diagnosis of sleep apnoea [e.g., obstructive sleep apnoea (OSA)]. It includes primary components such as sensors (e.g., air pressure sensor) and/or a control unit which may have some user-interface functionality, and typically additional devices which may include a gas sampling face mask and/or connecting leads/cables; collected data is transferred to a central database or computerized device.
