Nox A1 PSG System

Description

NOX A1s™

Portable and easy-to-use polysomnography system

Like its predecessor, the Nox A1s is an easy-to-use1, portable polysomnography (PSG) system that enables home-based or in-lab diagnosis of sleep-related breathing disorders. With an ergonomic design, the device has been developed to record a high-quality signal.

The Nox A1s is a versatile, compact and lightweight polysomnography (PSG) device that delivers high-quality signals while prioritizing patient comfort. Its dual functionality allows for both Type I in-lab sleep studies and unsupervised Type II home sleep studies.

FEATURES

• Ease-of-use
  Experience unparalleled simplicity with this redesigned, ergonomic PSG system. Its intuitive interface seamlessly integrates with the Noxturnal software and mobile app, streamlining workflows for both clinicians and patients. This user-friendly approach simplifies sleep studies, improves efficiency, and enhances the overall experience for everyone involved.

• Clinical accuracy
  Achieve diagnostic confidence with this comprehensive polysomnography system. Equipped with integrated respiratory inductance plethysmography (RIP) and a high-fidelity digital microphone, it captures precise physiological data for accurate sleep scoring and reliable diagnoses. This advanced technology empowers clinicians to confidently identify and assess sleep disorders, paving the way for effective treatment plans and improved patient care.

• Efficiency
  This cutting-edge PSG system leverages Bluetooth® Low Energy to ensure seamless data transmission, enabling real-time monitoring and synchronized video capture for comprehensive sleep studies. Equipped with a USB-C connection and Nox’s advanced high-resolution RIP technology, this device optimizes efficiency and accuracy for both in-lab and home sleep testing.

Nox SAS

Revolutionizing sleep diagnostics, the Nox SAS offers a groundbreaking approach to polysomnography. This innovative system captures EEG, ECG, and EMG signals through strategically placed forehead sensors, eliminating the need for cumbersome scalp and chin electrodes. This streamlined design empowers patients to undergo comprehensive sleep studies in the comfort of their own homes, with accuracy comparable to traditional in-lab PSG. Compatible with the Nox A1s system, the Nox SAS simplifies setup and data collection, saving valuable time for both clinicians and patients while expanding access to crucial diagnostic testing.
