CALIBRATION AND VALIDATION OF A PORTABLE WEARABLE DEVICE FOR VITAL SIGN MONITORING

Abstract

Monitoring vital signs is a crucial aspect of healthcare, as abnormal physiological changes serve as early indicators of serious conditions such as cardiac arrest and respiratory arrest [1]. Periodic manual monitoring systems are limited by their low recording frequency, which increases the risk of delayed detection [2]. The emergence of portable devices and wearable technologies, supported by wireless data transmission, enables continuous monitoring of vital signs not only in hospitalized patients but also in healthy populations and outpatients [3].
