Circadia Health

Circadia Health builds contactless patient monitoring tools that combine hardware, artificial intelligence and software to enable predictive care and reduce rehospitalizations across post-acute care. Its Circadia platform is described as the world's first FDA-cleared contactless patient monitoring system, designed to detect early signs of medical events such as heart failure, pneumonia and sepsis so that clinicians can intervene before conditions worsen.

The system is assembled from parts the company has built itself. The Circadia C200 uses radar to capture vital signs without touching the patient or requiring anything to be worn. A Clinical Intelligence Platform converts the resulting monitoring data into actionable clinical insight, and care coordination services act on that insight to close the loop on patient care. The engineering spans radar-based vital signs sensing, machine learning, predictive healthcare analytics, hardware engineering and clinical software development.

The deployed footprint is substantial: more than 30,000 patients are monitored every day, and rehospitalizations fell by 30% after 12 months in the reported results.

The work is carried out by a multidisciplinary team of engineers, scientists and physicians who build hardware, AI and software in-house, with an emphasis on asking the right questions and on establishing new standards of care rather than accepting existing ones.
