SOZO
Overview
The SOZO Digital Health Platform by ImpediMed is a cutting-edge, non-invasive bioimpedance spectroscopy (BIS) device designed to provide physicians with objective data for the early detection and ongoing management of lymphedema. Utilizing advanced BIS technology, SOZO offers a rapid, 30-second scan to measure extracellular fluid changes, a key indicator of lymphedema development. This proactive approach empowers clinicians to intervene earlier, potentially preventing the progression of lymphedema to more severe and debilitating stages.
SOZO generates an L-Dex score, a standardized index that quantifies fluid changes, enabling precise monitoring of patients at risk or those already undergoing lymphedema treatment. Beyond lymphedema, the device also performs comprehensive body composition analysis, providing insights into fluid status, body fat, and lean mass. This dual functionality makes SOZO a versatile tool for various clinical settings, from oncology and rehabilitation to general wellness and chronic disease management.
The platform is cloud-based, allowing for seamless data management, trend analysis, and secure access to patient information. Physicians can track changes over time, assess treatment efficacy, and personalize care plans based on objective, longitudinal data. SOZO’s intuitive touchscreen interface and wireless connectivity ensure ease of use within busy clinical workflows, while automated reporting streamlines documentation.
By integrating SOZO into their practice, physicians can enhance patient care through early intervention, improve patient outcomes, and provide a more data-driven approach to managing lymphedema and related conditions. The “my SOZO” patient portal further supports patient engagement by allowing individuals to access and understand their results, fostering a collaborative approach to health management.

What Physicians Need to Know
Leverage SOZO for objective, early detection and proactive management of lymphedema, particularly in at-risk cancer patients, by establishing baseline L-Dex measurements. Utilize its capabilities for fluid and body composition monitoring in other relevant conditions. Integrate SOZO scans into routine patient visits to streamline data collection and enhance care coordination through its EHR integration.
SOZO offers robust integration with Electronic Health Record (EHR) systems, including Epic, Cerner, and others, allowing for automatic, real-time transfer of measurement data. Its cloud-based platform ensures data accessibility for multidisciplinary care teams and facilitates remote software updates.
