Comparing Smartphone BPM Apps and Vital Signs Monitors for Pulse Measurement Accuracy

Abstract:

Technological advances in health have introduced new methods to monitor physiological parameters, particularly the integration of heart rate measurement capabilities into smartphone applications based on photoplethysmography (PPG) technology. These applications offer a more accessible alternative compared to conventional devices such as oximeters. This study aims to compare the accuracy of conventional oximeters and smartphone applications in measuring beats per minute (BPM). This study involved the simultaneous collection of heart rate data from 30 subjects using conventional oximeters represented by the Vital Signs Monitor (VSM) VT200A, and several smartphone applications. The data were then analyzed using Pearson's correlation coefficient to assess the consistency, reliability, and accuracy between smartphone applications and oximeters in measuring BPM under resting and active conditions. The results showed that of the three smartphone applications tested, the second application (application B) had the closest accuracy to the results from the VSM. Under resting conditions, the difference in measurements between the smartphone application and the VSM was around 1.47 - 3.13 BPM. However, during activity conditions, the difference increased to 2.87 - 5.93 BPM. Although smartphone applications can be used for everyday heart rate monitoring, for medical purposes it is still recommended to use a device that has been recognized as the gold standard, such as an oximeter.
