An IoT-Based Smart System with an MQTT Broker for Individual Patient Vital Sign Monitoring in Potential Emergency or Prehospital Applications

Figure 5

User profiles and physiological health parameters (essential vital signs) kept in the cloud platform developed in this paper. First, users access the website through a browser with their health ID card. The website generates visualized reports based on the measured data and displays a chart of data collected over the previous seven days to visualize the blood pressure trend. Other data can also be displayed side by side. User health is indicated by a red/yellow/green light indicator similar to a traffic signal for analysis and is then summarized from the user profiles and physiological health parameters. Users can also click on icons under the chart in Figure 5 to view the detailed data as a separate chart.
