easy to use and comfortable to wear

Zmachine® Synergy

Combining FDA-cleared EEG-based sleep staging technology with traditional respiratory measures, the Zmachine Synergy delivers everything you’d expect in a next generation home sleep testing system. General Sleep didn’t invent the home sleep test, they just made it better!™

Patient Friendly

Designed for easy application and comfortable sleep

Integrated Sleep Staging

Sleep staging based on EEG, not movement

Reliable Signals (9 Channels)

High quality signals for results you can trust

Easy for Patients
With crystal clear instructions, ultra-small package, and a streamlined setup procedure, your patients will find the Zmachine Synergy easy to use and comfortable to wear during sleep.
Easy for Providers
Score and interpret the data yourself, or let Zmachine's team of expert registered PSG technologists and board certified sleep physicians (licensed in all 50 states) handle everything for you with scoring and physician reports available within 48 hours of data upload. All data is viewable and editable via Zmachine's advanced web portal.
Full Range of Signals
EEG-based sleep staging, respiratory airflow, snore, CPAP flow, CPAP pressure, respiratory effort (RIP), 3-axis body position & activity, and pulse oximetry make this system complete and ready to use.
Advanced Sleep Reports
With the addition of EEG-based sleep staging and a 3D body position sensor, the AHI is calculated on sleep time, REM time, and sleep position (not simply recording time). This results in accurate and informative AHI values, especially for those patients with lower severity, difficulty sleeping, and those with position dependent symptoms. The addition of EEG also enables the reporting of RERAs (i.e. non-desaturating hypopneas terminating with EEG arousals) for improved event reporting.
