by Compumedics • Model: Somfit
The Somfit is an FDA-cleared, clinical-grade wearable device that records physiological signals directly from the patient's forehead. It uniquely combines frontal EEG/EOG measurement with PAT-based technology, high-resolution oximetry, and acoustic sensors to provide a comprehensive analysis of sleep-disordered breathing and true sleep architecture.
Eligibility may vary by provider and plan. Check with your HSA/FSA administrator for specific details.
Evidence-based evaluation by medical professionals
"A clinical breakthrough that provides laboratory-grade sleep architecture and apnea detection via a minimalist forehead patch."
The Compumedics Somfit represents a significant evolution in home sleep testing (HST) by integrating true neurophysiological signals into a Level 3 (Type III) portable device. While many competitors rely on indirect activity-based metrics for sleep staging, the Somfit captures two channels of true EEG (Fp1, Fp2), alongside EOG and EMG proxies, directly from its forehead-worn position. This allows for a clinically validated hypnogram (Wake, N1, N2, N3, REM) with an overall staging agreement of 76% compared to human PSG scoring-a performance level non-inferior to standard inter-scorer variability. Our review highlights its high correlation with gold-standard PSG for the Apnea-Hypopnea Index (AHI, r > 0.84) and Total Sleep Time (TST, r = 0.94). The platform is highly scalable, offering a reusable sensor module for longitudinal care and the 'Somfit D' fully disposable version for high-volume screening without return logistics.
