Circadia Health offers AI-powered contactless patient monitoring for senior care using a radar bedside device to measure respiratory rate, heart rate, motion, and bed exits from up to eight feet away without touching the patient. Its proprietary AI analyzes the data to predict potential medical events hours or days in advance, with 24/7 virtual nurses reviewing alerts and integrating with electronic health records. The service runs on a subscription model for skilled nursing facilities and long-term care providers, and is designed to help reduce hospitalizations and lower costs, with Medicare remote monitoring reimbursement. Its approach combines non-contact radar sensing, multi-parameter monitoring, FDA-cleared devices, and end-to-end service focused on long-term care to shift from reactive to proactive care.
