Methods for Breathing Rate Measurement through Mobile Platform: a Review

Abstract

Breathing rate is a vital sign that can indicate someone’s health status and even detect early diseases. Mobile health applications might become the main tool for estimating breathing rate out of the clinical environment. In this research, a review of the literature is conducted, aiming at finding out the most recent researches that have been proposed as solutions for respiratory measurement or monitoring using mobile devices. We discuss and compare their methods, highlighting pros and cons regarding ubiquity and feasibility. The results indicate that the combination of methods is a key aspect to improve measurements.
