Combining our 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. We didn’t invent the home sleep test, we just made it better!™
Designed for easy application and comfortable sleep
Sleep staging based on EEG, not movement
High quality signals for results you can trust
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.
Score and interpret the data yourself, or let our 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 our advanced web portal.
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.
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.

All signals are checked automatically, and intuitive LED indicators located next to each connector clearly confirm the operation of each sensor. Each sensor uses a unique connector to prevent hookup mistakes.

Distinguished from other home sleep tests, the Zmachine Synergy uses the EEG signal to determine sleep information (not the presence or absence of physical movement). Using our FDA-cleared single-channel EEG algorithms, the Synergy automatically scores wake, light sleep (N1 & N2), deep sleep (N3), REM, and arousals every 30 seconds. The self-stick, disposable, EEG sensors are easy to apply/remove, and unobtrusive to wear during sleep.

The Zmachine Synergy uses the same technology to acquire and process EEG data as the Zmachine Insight/Insight+.
