Remote sensing of multiple vital signs using a CMOS camera-equipped infrared thermography system and its clinical application in rapidly screening patients with suspected infectious diseases

Abstract

Multiple vital-sign-based screening efficiently detected patients with suspected infectious diseases. It offers a promising alternative to conventional fever-based screening.

Vital-SCOPE: Design and Evaluation of a Smart Vital Sign Monitor for Simultaneous Measurement of Pulse Rate, Respiratory Rate, and Body Temperature for Patient Monitoring

“…However, such measurements require the attachment of sensors, which can cause discomfort and place a heavy burden on patient. In recent years, a variety of unobtrusive medical sensors have been developed for long-term or intermittent physiological measurements, including RGB visible and thermal images for measuring heart and respiratory rates [7] and measurement of cardiac and respiration pulses using laser Doppler or a microwave medical radar [14,15]. These noncontact sensors have their advantages and disadvantages depending on the specific applications.…”

“…In our previous studies, we proposed a multiple vital sign-based infection screening system with sensor fusion technology that can rapidly perform medical inspections at places of mass gatherings, such as airport quarantine stations and outpatient units [7][8][9][10]. This multiple sensor system consists of a medical radar and an infrared thermographic camera.…”

The Use of Digital Health in the Detection and Management of COVID-19

“…Integrated Health Information Systems and KroniKare are currently piloting a screening solution that automatically screens and identifies patients with symptoms such as fever [20]. Sun et al [21] recommend using a microwave radar to capture heart rate and respiratory rate to enhance the accuracy of mass screening. Additional research is needed to validate and develop mass temperature screening solutions.…”

Doctor Drone: Non-invasive Measurement of Humpback Whale Vital Signs Using Unoccupied Aerial System Infrared Thermography

“…Future opportunities created by the UAS-IRT results we report center on the potential to couple non-invasive behavioral and physiological monitoring tools, quantify cetacean response to prolonged environmental change and acute disturbances, and extend INTRODUCTION Biomedical vital signs, including respiration rate, body temperature, and heart rate are important indicators of mammalian health and physiological condition. Although technological advances in infrared thermography (IRT) and signal processing have facilitated measurement of human vital signs (e.g., Sun et al, 2017), such techniques are not yet widely applied to marine mammals. Although prior marine mammal research has used IRT to measure the dorsal fin surface temperatures of free-swimming bottlenose dolphins (Tursiops truncatus) during small boat surveys (Barbieri et al, 2010) and thermal reference points on captive marine mammals (Melero et al, 2015), airborne IRT has been limited to estimating pinniped colony size using both aircraft (Udevitz et al, 2008) and unoccupied aerial systems (UAS; Seymour et al, 2017).…”

“…Our study helps to overcome this challenge through quantification of cetacean brightness temperatures from low zenith angles. A second goal of our research was to explore the possibility that high frame rate UAS-IRT was capable of capturing cyclical changes in whale dorsal fin temperatures consistent with cardiovascular circulation (e.g., Sun et al, 2017). This is an important goal to pursue, as there are currently no conventional approaches for measuring cetacean heart rates in the wild.…”
