“…Section A illustrates the wearable devices connected to patients to collect vital signs such as heart rate, pulse rate, respiratory rate, breathing rate, body temperature, and so on. In Section B, the collection will be stored in cloud services (Neto et al, 2017; Shao et al, 2020; Shi et al, 2020) for further analysis using machine learning methodologies that could predict or classify the patient data. The process could then estimate any abnormal events in the near future based on known threshold values of the vital signs and update medical staff or healthcare professionals (Ankita et al, 2021; Bekiri et al, 2020; C. Liu et al, 2019; Lin et al, 2018; Devi & Kalaivani, 2019; Efat et al, 2020; Shao et al, 2020) in Section C of the architecture.…”
