As students working on a healthcare technology project, we recognize the importance of understanding the medical frameworks that guide emergency care. While our focus is on developing a technological solution, it is essential that we align our system with real-world clinical practices. Recently, the doctors advising us recommended a key NHS document on emergency department triage and acuity measurement. This document serves as a foundation for our learning, offering insights into how patients are assessed and prioritized in emergency settings.

In the development of our Dynamic Emergency Monitoring System (DEMS), selecting the right sensor for real-time heart rate and oxygen saturation (SpO₂) monitoring is a critical decision. After evaluating multiple options, we chose the MAX30102, a highly efficient optical sensor designed for non-invasive measurement of vital signs. Its compact design, low power consumption, and high accuracy make it an ideal choice for wearable medical applications, particularly in emergency settings where continuous monitoring and immediate alerts are essential.

As we develop the Dynamic Emergency Monitoring System (DEMS), selecting the right sensors for patient monitoring is crucial. In addition to vital sign tracking, motion analysis plays a key role in detecting critical events such as falls, sudden movements, or patient distress. For this purpose, we have chosen the ADXL345, a highly efficient 3-axis accelerometer that offers precise motion tracking while maintaining low power consumption—a critical feature for our wearable monitoring system.

As part of our ongoing development of the Dynamic Emergency Monitoring System (DEMS), we are now focusing on evaluating individual sensors that will eventually be integrated into our wearable prototype. One of the most critical health indicators we intend to monitor is body temperature- a vital sign that often serves as an early warning for infection, inflammation, or systemic distress.[ https://en.wikipedia.org/wiki/Vital_signs] To test this, we selected the LM35DZ, a popular analog temperature sensor, for the first phase of our concept validation.

As our project continues to evolve from concept to implementation, one of the most significant decisions we’ve made recently concerns the infrastructure for edge computing. After technical evaluations and a recommendation from our Scientific Advisor, Prof. Teresa Vazão, we are going to use the Raspberry Pi 4 Model B (1GB) as the local computing hub to serve as the intermediary between wearable devices and the central system.

As part of our project, we've just launched the first working iteration of our dashboard—built in Vue.js—to help healthcare professionals make faster, data-driven decisions. Designed for clarity and ease of use, this interface displays each patient's vital information at a glance, and highlights critical changes the moment they occur.

As we advanced in the development and testing of our Dynamic Emergency Monitoring System (DEMS), one of the most important tasks was ensuring reliable and practical temperature measurement in real-world scenarios. Initially, we began testing with the LM35DZ analog temperature sensor due to its simplicity, affordability, and ease of integration into early prototypes. However, as we transitioned from concept to more applied testing, critical limitations began to emerge — ultimately leading us to explore a better solution: the MLX90614 infrared temperature sensor.
