Product Description

High-resolution, Bluetooth-enabled oximeter for extended sleep and respiratory monitoring

The Nonin WristOx2 3150 BLE is a clinical-grade wristwatch oximeter designed for accurate, high-resolution pulse oximetry over extended periods. With a memory capacity of 270 hours, high SpO₂ resolution stored at 1 Hz, and up to 44 hours of battery life, it is ideal for multi-night recording in sleep and respiratory studies.

The 3150 BLE offers flexibility, comfort, and fast USB data transfer. It supports a wide range of Stowood-compatible finger probes and is suitable for both clinical and home-based use in sleep apnoea screening, home oxygen assessments, and non-invasive ventilation (NIV) monitoring.

• Lightweight and unobtrusive design improves patient compliance

• Battery-powered operation with no recharging downtime

• Bluetooth option enables potential real-time data streaming in research settings

• Backward-compatible with a variety of Stowood-supplied probes

Typical Applications

• Sleep apnoea screening (home or clinic-based)

• Assessment of long-term oxygen therapy (LTOT)

• Monitoring during non-invasive ventilation (NIV)

• Multi-night studies in research or field-based settings

For Sleep Technicians

The WristOx2 3150 BLE is ideal for unattended home sleep studies, with flexible memory and reliable battery operation. Quick setup and probe versatility ensure suitability across patient types, and the ability to download detailed datasets with Visi-Download supports efficient workflow and accurate scoring.

For Sleep Consultants

Clinicians benefit from high-resolution trend data comparable to the Pulsox-300i, supporting confident diagnosis and therapy evaluation. The extended memory allows for multiple-night assessments, while the BLE capability may support future remote monitoring applications.

For Researchers into Sleep

With 1 Hz data resolution, long recording duration, and fast data transfer, the 3150 BLE is well-suited for sleep research protocols. It provides a balance of precision, patient comfort, and hardware simplicity ideal for large-scale or ambulatory studies.
