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

## TL;DR

This study aims to test if remote photoplethysmography can accurately measure heart and respiratory rates in children compared to traditional methods.

## Contribution

The study introduces a novel protocol for evaluating rPPG in pediatric populations for vital sign monitoring.

## Key findings

- 600 pediatric participants will be enrolled for simultaneous rPPG and standard monitoring comparisons.
- Intraclass correlation coefficients will assess agreement between rPPG and standard measurements.
- Findings will be published in peer-reviewed journals and disseminated widely.

## Abstract

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.

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.

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.
