Measurement of heart rate and respiratory rate using remote photoplethysmography in paediatrics: a prospective comparative trial protocol – ‘rMonitoped1’

Introduction Vital signs such as heart rate (HR) and respiratory rate (RR), crucial for clinical assessment, are often challenging to measure in paediatric populations. Remote photoplethysmography (rPPG), a video-based measurement tool, has demonstrated accuracy in adults. The objective of this study is to compare HR and RR measurements obtained using rPPG with those from standard clinical monitoring in a paediatric population. Methods and analysis This is a monocentric, prospective study enrolling 600 paediatric participants. Each participant will have standard monitoring electrodes (ECG/impedance) placed on the chest while seated facing a camera for rPPG recording. Simultaneous HR and RR measurements will be recorded over periods of 30 and 60 s using both the standard monitor and the rPPG device. The intraclass correlation coefficient will be calculated to assess agreement between the rPPG and standard monitor measurements. Ethics and dissemination The study protocol has been approved by the French Agency for the Safety of Health Products (ANSM (Agence nationale de sécurité du médicament) registration no. IDRCB 2023-A02524-41) and by a French ethics committee (CPP Sud Méditerranée III at 29 August 2024, n°2024-A01324-43). The study’s findings will be published in peer-reviewed journals and disseminated at national and international conferences and through press releases. Trial registration number Clinical Trials Registry ( NCT06231654 ).
