Innovative measurement of routine physiological variables (heart rate, respiratory rate and oxygen saturation) using a remote photoplethysmography imaging system: a prospective comparative trial protocol

IntroductionPhysiological signals are essential for assessing human health. The absence of a medical device to carry out these measurements remotely is one of the main limitations of telemedicine.

Description
Summary:IntroductionPhysiological signals are essential for assessing human health. The absence of a medical device to carry out these measurements remotely is one of the main limitations of telemedicine. Remote photoplethysmography imaging (rPPG) makes it possible to use a camera video to measure some of the most valuable physiological variables: heart rate (HR), respiratory rate (RR) and oxygen saturation (SpO2). Our objective was to evaluate the value of such remote measurements compared with existing contact point measurements techniques in real-life clinical settings.Methods and analysisProspective hospital-based study that will recruit 1045 patients who require a pulmonary function test. For each patient, measurements of HR, RR and SpO2, using a standard acquisition system, will be carried out concomitantly with the measurements made by the rPPG system. 30, 60 and 120 s time frames will be used to take measurements. Age, gender and skin phototype will also be collected. The intraclass coefficient correlation will be performed to determine the accuracy and precision of the rPPG algorithm readings.Ethics and disseminationThe study protocol has been approved by the French Agency for the Safety of Health Products (ANSM registration no. ID RCB 2020-A02428-31) and by a French ethics committee (CPP OUEST I-TOURS-2020T1-30 DM at 30 October 2020). Results will be published in peer-reviewed journals, at scientific conferences and through press releases.Trial registration numberNCT04660318.
