Loop System
Overview
The Loop System by Spry Health was a clinical-grade wearable device designed for continuous remote patient monitoring. It was not an AI tool for a physician directory, but rather focused on managing chronic diseases, particularly Chronic Obstructive Pulmonary Disease (COPD).
The system utilized optical sensors on a wristband to non-invasively measure key vital signs such as pulse oximetry, respiration rate, and heart rate. Its analytics platform was built to pinpoint subtle physiological changes and deliver actionable insights to healthcare organizations, enabling early detection of patient deterioration before symptoms became noticeable. This approach aimed to improve patient outcomes, reduce hospitalizations, and decrease healthcare costs.
Spry Health was founded in 2014 and headquartered in Palo Alto, CA. The company and its Loop System technology were acquired by Itamar Medical in January 2021, which was subsequently acquired by Zoll Medical in December 2021. Information regarding current availability or standalone operation of the ‘Loop System’ under the Spry Health brand is limited post-acquisition.

What Physicians Need to Know
When evaluating the Loop System, focus on how its predictive capabilities align with your specific clinical workflows and patient populations. Prioritize understanding its integration with your EHR to ensure minimal disruption. Engage with the vendor's support team during the pilot phase to address any workflow friction. Always critically assess the AI's recommendations in the context of your clinical judgment and patient-specific factors. Verify the transparency of its algorithms and the quality of its evidence base.
Effective integration with existing Electronic Health Record (EHR) systems is paramount for the Loop System's success. Seamless data flow ensures real-time insights and avoids duplicate data entry, maximizing clinical utility and minimizing physician burden. Prioritize vendors that offer robust, secure, and well-documented API options, ideally leveraging industry standards like FHIR, to ensure future compatibility and scalability.
