Clinical Review

Evidence-based evaluation by medical professionals

"The premier choice for at-home sleep diagnostics, offering laboratory-grade EEG staging and calibrated respiratory effort in a tiny, 92g wireless recorder."
Strong Clinical Evidence Highly Recommended

Score

The Nox A1s PSG System represents the pinnacle of 'Hospital-to-Home' sleep technology. Unlike traditional home sleep tests that only provide a screening (Type III or IV), the A1s is a fully capable Level II polysomnogram that records up to 32 channels of data, including true EEG for definitive sleep staging. This depth of data allows clinicians to perform comprehensive diagnostics in the patient's own bed without the tethering and discomfort of a lab environment. Our clinical evaluation highlights its 24-bit signal processing and 256 kHz sampling rate, which ensures signal synchrony and minimal artifact even during movement. Its integration with Nox BodySleep™ 2.0 further leverages deep learning to score sleep states and arousals with human-level accuracy, providing a robust AHI value that closely aligns with gold-standard PSG results. For clinics, it offers a 5x expansion in service capacity by allowing attended-quality studies to be performed unattended at home.
