Contactless and Calibration-Free Blood Pressure and Pulse Rate Monitor for Screening and Monitoring of Hypertension: Cross-Sectional Validation Study

Contactless and Calibration-Free Blood Pressure and Pulse Rate Monitor for Screening and Monitoring of Hypertension: Cross-Sectional Validation Study

Pulse rate (PR) is another vital sign that can be beneficial to monitor in people with hypertension. The COVID-19 pandemic highlighted the heightened risk of infectious diseases in people with hypertension; a 2.5-fold increase in severity and mortality was observed [19]. It has been shown that presymptomatic infections such as COVID-19 can be detected by regular monitoring of heart rate (HR) [20].

The Accuracy of Pulse Oxygen Saturation, Heart Rate, Blood Pressure, and Respiratory Rate Raised by a Contactless Telehealth Portal: Validation Study

The Accuracy of Pulse Oxygen Saturation, Heart Rate, Blood Pressure, and Respiratory Rate Raised by a Contactless Telehealth Portal: Validation Study

Heart rate (HR), blood pressure (BP), oxygen saturation (Sp O2), and respiratory rate (RR) are the 4 cardinal vital signs. The measurement of these vital signs is the starting point of physical assessment for both health and wellness. The traditional measurement of these vital signs through physical examination can be challenging, and the recent pandemic has accelerated trends toward telehealth and remote monitoring.

Effect of Digital Early Warning Scores on Hospital Vital Sign Observation Protocol Adherence: Stepped-Wedge Evaluation

Effect of Digital Early Warning Scores on Hospital Vital Sign Observation Protocol Adherence: Stepped-Wedge Evaluation

Such deterioration often corresponds with deviations in patient vital signs early warning score (EWS) algorithms have been introduced to improve the recognition of abnormal vital signs [2]. They assign a score to each vital sign value according to the degree of abnormality. The total score is a measure of patient risk. Many EWS algorithms have been published and their use is mandated by the National Institute of Health and Care Excellence in the United Kingdom [3,4].
