Product Description Comfortable, high-resolution wrist oximeter for sleep and respiratory assessment The Checkme O2 MAX is a lightweight, wrist-worn oximeter designed for comfortable, extended monitoring of oxygen saturation, pulse rate and motion. It features a unique ring-style sensor, offering superior patient comfort and improved compliance for overnight use. With four-night memory capacity, high SpO₂ resolution (stored at 0.5 Hz), and up to 72 hours of battery life, the device is well-suited to both clinical and home-based screening. Intended for sleep apnoea screening, home oxygen therapy assessments, and non-invasive ventilation (NIV) monitoring, the Checkme O2 MAX provides accurate and accessible data collection in a patient-friendly form factor. N.B. This is not an actigraph. SpO2 detection technologies take too much battery to be used as long as an actigraph needs to. Key Features Wristwatch-style oximeter with intuitive design and lightweight form High-resolution SpO₂, pulse rate and motion storage at 0.5 Hz Motion recording trace facilitates wake/sleep judgement Four-night memory capacity for extended monitoring, each of ten hours maximum recording 72-hour battery life on a single charge Ring sensor for superior comfort and patient compliance Fast USB data transfer – 8 hours of data downloads in ~10 seconds Compatible with Visi-Download software using the supplied interface cable Internal rechargeable battery with ~3-year lifespan Software Compatibility The Checkme O2 MAX integrates with Visi-Download software for fast data access and review. Using the included USB interface cable, full overnight recordings can be downloaded in seconds, supporting quick turnaround for reporting and analysis. Benefits Enhances patient comfort with non-intrusive ring sensor Improves study compliance and data reliability Ideal for multi-night monitoring and follow-up screening Lightweight and wearable – perfect for at-home deployment Fast data access streamlines clinician workflow Multiple probe options available for different patient groups Typical Applications Overnight sleep apnoea screening Long-term oxygen therapy (LTOT) assessment Monitoring during non-invasive ventilation (NIV) Remote and home-based respiratory evaluation For Sleep Technicians The Checkme O2 MAX is easy to deploy for home studies, offering reliable overnight recordings with minimal setup. The soft, ring-style sensor ensures comfort throughout the night and reduces dislodgement. With rapid data download via USB, analysis and reporting can be completed efficiently using Visi-Download. Stowood have created a ‘hook up’ video which you can share with patients using a link or QR code for easy linking from a patient information leaflet or similar. For Sleep Consultants Consultants benefit from high-resolution SpO₂ data that supports the diagnosis and management of respiratory conditions. The multiple nights of recording and improved patient compliance make the Checkme O2 MAX a reliable tool for screening and follow-up, particularly in patients using oxygen therapy or NIV. For Researchers into Sleep The Checkme O2 MAX enables multi-night monitoring in natural settings, providing high-quality, high-frequency data ideal for longitudinal or behavioural studies. Fast download and compatibility with research workflows make it a practical tool for data collection across diverse populations.
