Are BP Rings the Future of Ward Monitoring?

Why It Matters

Automating routine BP checks can free significant nursing time, reduce documentation errors, and improve patient comfort, accelerating the shift toward smart‑hospital operations.

Key Takeaways

• CART ON ring automates ward blood pressure measurements
• Mean error 5 mmHg, SD 8 mmHg meets ISO standards
• Potential to free up ~60 nurse checks per 15‑patient ward
• Reduces patient discomfort and nighttime sleep disruptions
• Daewoong to distribute ring across South Korean hospitals

Pulse Analysis

The emergence of cuffless, ring‑type blood‑pressure monitors reflects a broader move toward wearable health technology that blends clinical accuracy with patient convenience. By leveraging photoplethysmography and machine‑learning models trained on invasive arterial line data, Sky Labs’ CART ON achieves validation metrics comparable to traditional auscultation, satisfying ISO and European Society of Hypertension criteria. This technical credibility is crucial for hospital adoption, where measurement fidelity directly influences treatment decisions and regulatory compliance.

Beyond accuracy, the operational impact of automated BP monitoring is profound. In Korean wards, nurses typically perform up to 100 manual cuff readings daily across 12‑20 patients. CART ON’s seamless integration with the thynC platform streams real‑time data to nurse‑station dashboards and electronic medical records, eliminating manual entry and reducing the risk of transcription errors. The resulting time savings—estimated at 60 automated checks per 15‑patient unit—allow clinicians to focus on higher‑value tasks such as patient assessment and care coordination, while also minimizing nighttime disturbances for patients sharing rooms.

Strategically, the rollout positions Sky Labs at the forefront of the smart‑hospital ecosystem, complementing its consumer‑focused BP ring and recent partnership with Kakao Healthcare’s PASTA platform. As hospitals worldwide prioritize labor efficiency and continuous monitoring, the CART ON ring could serve as a template for broader wearable integration, prompting competitors to accelerate their own cuffless solutions. Daewoong Pharmaceutical’s distribution network will accelerate market penetration in South Korea, potentially setting a precedent for global adoption and influencing future regulatory pathways for wearable medical devices.
