This is crucial for time-sensitive applications, such as monitoring critical patients or emergency response.

3. Data Collection and Transmission (IoT and IoMT)

   • Internet of Medical Things (IoMT): The IoMT includes wearables, sensors, and interconnected medical devices that continuously gather real-time patient data. Devices like heart monitors, glucose trackers, and activity trackers transmit data directly to healthcare providers for ongoing analysis, helping to detect health issues early and provide personalized care.

4. Digital Health Services and Applications (Telehealth, EHR, PHR, and RTHS)

   • Electronic Health Records (EHRs): These are digital versions of patient charts maintained by healthcare providers, containing essential medical histories, treatment plans, and test results.
   • Telehealth and Remote Patient Monitoring: These technologies allow patients to receive medical care from home, reducing the burden on healthcare systems and expanding access to care.
   • Real-Time Health Systems (RTHS): RTHS provides a vision for healthcare where digital health data enables real-time monitoring, analysis, and decision-making, creating a responsive environment for patient care.

5. Advanced Analytics and AI in Medicine
