Proof of concept: Remote investigation and assessment of vital signs
The first independent clinical study using the Detectivio method has been published in the scientific journal Infectious Diseases.
The research findings show promising results for the technology. The study included four vital parameters and was conducted in 2020 in the emergency department at Sahlgrenska Östra Sjukhuset. Professor Ronny Gunnarsson, Sahlgrenska Academy, University of Gothenburg, was in charge of the study.
Subsequent clinical validation
The next iteration of clinical validation of Detectivio’s technology is a collaboration with the Sahlgrenska Academy and Västra Götalandsregionen. The clinical investigation tests the new clinical-grade prototype with close to 1600 measurements to validate the accuracy and reliability.
Approved by the Swedish Ethical Review Authority and Swedish Medical Products Agency, the study started 2022.
Seconds Matter: Rapid Non-Contact Monitoring of Heart and Respiratory Rate from Face Videos
Accurate, non-contact vital-sign monitoring promises a scalable alternative to conventional sensors, yet low signal quality and long recording times have limited real-life adoption. We present a dual-modality system that combines Eulerian video magnified remote photoplethysmography (rPPG) from facial videos with optical flow-based shoulder tracking to estimate heart rate (HR) and respiratory rate (RR) from ultra-short 15 s recordings.
Contactless vital signs measurement along the patient journey: design for explainable AI solutions
This paper presents a user-centered design framework for integrating contactless vital signs measurement into clinical workflows. Since this technology is not yet widely deployed in standard clinical use, its use implies novel design challenges.
