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 the Web Says
The "Loop System" generally refers to automated insulin delivery (AID) systems for managing Type 1 diabetes, as well as clinical collaboration platforms and customer feedback systems. Reviews from physicians and users of AID systems highlight significant improvements in glycemic control, quality of life, and reduced burden of diabetes management. Clinical collaboration platforms aim to improve communication among care team members, though some usability challenges have been noted. Customer feedback Loop systems are praised for providing real-time insights and improving service.
Overall: PositiveStrengths
- Improved glycemic control and lower HbA1c levels for diabetes management.
- Increased time in range and fewer highs or lows for diabetes patients.
- Reduced mental and behavioral burden of diabetes management.
- Enhanced communication and collaboration among healthcare team members.
- Real-time customer feedback and ability to adjust services quickly.
- Customizability and educational benefits for users of open-source AID systems.
Limitations
- Initial difficulty in understanding/operating some Loop systems.
- Potential disruptions to personal workflow due to additional time or task requirements for clinical collaboration systems.
- Some providers express concerns about open-source AID systems not being FDA approved.
- Closed-loop systems for diabetes can fail, requiring backup supplies.
- The Loop algorithm may perform poorly with long-slow protein burns for some diabetes patients.
- System maintenance and potential for frequent alarms in early stages of diabetes management systems.
