About Nox Medical Ehf

Nox Medical Ehf is an Icelandic healthcare technology company established in 2006 by a collaborative team of engineers, investors, and medical professionals. The company specializes in developing and providing advanced solutions for sleep monitoring and diagnostics, with a core mission to enhance sleep medicine through simplification, increased efficiency, and superior patient comfort, including for pediatric populations. Their product portfolio features innovative portable sleep monitors, such as the Nox T3s for home sleep testing and the Nox A1s Polysomnography (PSG) system for both in-lab and ambulatory studies, both designed to meet AASM standards. These devices integrate cutting-edge wireless technology, advanced sensors, and robust electronics to ensure reliable and precise data acquisition.

Beyond hardware, Nox Medical offers the sophisticated Noxturnal software, which provides automated analysis, scoring, and reporting capabilities, significantly streamlining the interpretation of complex sleep studies for physicians. The company is a proactive innovator, heavily investing in research and development, particularly in the fields of Artificial Intelligence (AI) and machine learning. These AI initiatives are geared towards improving diagnostic accuracy, personalizing treatment protocols, and optimizing the overall patient journey in sleep health. Key areas of AI focus include clinical validation, refining measurement technologies for more accurate and diverse datasets, and developing novel algorithms, such as Nox BodySleep, to extract deeper insights from sleep study data.

Nox Medical operates as a business unit under Nox Health, a global leader in sleep health formed in 2020 through the merger of Nox Medical and FusionHealth. This integration allows for a comprehensive approach to sleep care, combining advanced diagnostic technology with broader sleep management solutions.

What Physicians Need to Know

Sleep Monitoring & Diagnostics
Nox Medical offers comprehensive solutions for both in-lab Polysomnography (PSG) with the Nox A1s and Home Sleep Testing (HST) with the Nox T3s system. Their devices are designed for high signal quality and patient comfort, minimizing wires and simplifying setup.
AI for Sleep Analysis
Pioneering FDA-cleared AI tools like DeepRESP and Nox BodySleep enable advanced sleep staging and arousal detection directly from respiratory signals, even without EEG. Their AI also assists in scoring AHI, periodic limb movements, and provides insights into OSA endotyping, hypoxic burden, and ventilatory burden.
Cloud-Based Platforms
Nox Connect is a unified, secure, cloud-based platform that streamlines the entire sleep diagnostics workflow, from patient management and testing to AI-assisted scoring and interpretation. It supports web-based scoring and real-time access to data, enhancing collaboration and operational efficiency.
Digital Therapeutics
Through Nox Health, they offer Somryst, the first FDA-cleared Prescription Digital Therapeutic (PDT) for chronic insomnia, delivering Cognitive Behavioral Therapy for Insomnia (CBT-I) via a mobile application.
Sleep Apnea Phenotyping (Endotyping)
Nox Medical is at the forefront of sleep apnea endotyping research, utilizing their patented Nox RIP technology and AI tools like DeepRESP to identify underlying physiological traits (collapsibility, loop gain, arousal threshold, muscle compensation). This enables a more personalized approach to treatment.
Home Sleep Testing as a Service (HSTaaS)
Nox offers a fully integrated Home Sleep Testing Service through Nox Connect, which includes test ordering, kit delivery, patient support, and AI-enhanced scoring, allowing practices to scale diagnostics without needing to manage device inventory.
Physician Tip

For physicians, Nox Medical stands out by offering enhanced diagnostic accuracy and confidence through physiology-grounded data (Nox Flow) and FDA-cleared AI tools that provide deeper insights beyond the AHI, such as ventilatory and hypoxic burden, and OSA endotyping. This allows for more personalized treatment decisions. The Nox Connect cloud platform streamlines workflows, reduces administrative burden, and enables scalable, remote diagnostics, improving efficiency and patient access to care. The integration of digital therapeutics like Somryst expands the treatment options available for chronic insomnia.

Nox Connect is exclusively compatible with Nox sleep diagnostic recorders and data, ensuring seamless performance. It integrates with Noxturnal Desktop for configuration and upload, and Noxturnal Web for reviewing auto-scored studies. While Noxturnal itself does not directly receive or return HL7 communication, it can exchange patient data with integration engines that interpret HL7 messages by reading from and exporting to databases, requiring some IT modification for full HIS integration. The Nox Cloud infrastructure is built on Amazon Web Services (AWS) and holds ISO 27001, SOC 1 Type 2, SOC 2 Type 2, and HITRUST security and compliance certifications, adhering to HIPAA and GDPR.
