– The Interesting Features
Regardless of the examination model required for your patients, Sonata provides versatile solutions for a wide range of applications. A high degree of patient comfort, reliable diagnosis, and efficient handling of both hardware and software are at the core of its design.
Sonata – The 65-Channel PSG System
With its 65 channels, Sonata offers extensive options for recording patient parameters. During sleep studies, respiratory events such as apneas are recorded, sleep quality is assessed via EEG measurements, oxygen saturation levels are monitored, and leg movements along with other parameters are measured, analyzed, and interpreted.
AASM Compatibility
Sonata operates in accordance with the AASM manual, which defines standardized measurement setups, electrode placement guidelines, digitization parameters, and sleep scoring criteria.
Unmatched Economic Efficiency
Sonata is designed for cost efficiency with low follow-up costs. Durable sensors ensure long-term usability, while the system enables quick and easy application by staff without compromising signal quality.
