Built for labs that score every epoch
Sonata is a full Level 1 in-lab PSG platform — EEG, EOG, EMG, ECG, SpO₂, airflow, respiratory effort, snoring and limb movement, recorded and reported in a single overnight study, to AASM standard.
AASM-compliant throughout
Electrode placement, digitisation parameters and sleep staging follow the AASM manual, so reports hold up for accreditation and referral.
High-resolution EEG module
Clean, artifact-free neurological traces for REM behaviour disorder, nocturnal seizure activity and other cases where a respiratory-only channel set isn’t enough.
Low cost per study
Durable, reusable sensors and low follow-up cost keep the operating expense per night down over the life of the lab.
Fast to apply, quick to learn
Intuitive software and rapid electrode application — staff reach reliable montages with minimal training, without trading away signal quality.
CPAP & BiPAP titration
Integrates with Löwenstein therapy devices including prismaLAB and prismaSMART, so pressure and sleep parameters are monitored together during titration.
