https://matjournals.net/engineering/index.php/JCIE <p>Journal of Control and Instrumentation Engineering is a print e-journal focused towards the rapid Publication of fundamental research papers on all areas of control and instrumentation engineering. The typical Control and Instrument Engineer will be expected to be fluent in electronics, fluid dynamics, material selection, control engineering, and systems engineering amongst all the usual competencies expected of today's professional engineer.</p> en-US Journal of Control and Instrumentation Engineering https://matjournals.net/engineering/index.php/JCIE/article/view/4277 <p><em>A road medical emergency is governed by two separate delays: how long the ambulance takes to reach the hospital, and how long the patient then spends being handed over from the ambulance to the intensive care unit (ICU). This paper targets the second of these by building and bench-testing a low-cost Internet of Things (IoT) system that pairs an ambulance-side patient-monitoring kit with an automated, radio-triggered stretcher. An Arduino UNO-based acquisition unit reads a patient's heart rate, blood-oxygen saturation (SpO2), and body temperature throughout transit and pushes the readings to a ThingSpeak cloud dashboard over an ESP8266/ESP01 Wi-Fi link, letting ward staff see the incoming patient's condition before the vehicle arrives. Separately, a 433 MHz radio-frequency (RF) link between the ambulance kit and a NodeMCU-controlled motorized stretcher detects ambulance proximity and releases the stretcher toward the drop-off point, removing the need for staff to fetch it manually. A working prototype of both units was built; ten consecutive vital-sign samples logged at 10-second intervals confirm sensor consistency, and the RF-triggered drive actuated reliably across bench trials. The design is then discussed against 2023–2026 developments in acoustic and AI-based ambulance detection, connected-vehicle signal preemption, and autonomous in-hospital patient-transport robots, closing with a roadmap toward obstacle-aware navigation and city-scale green-corridor integration.</em></p> Arunkumar S.
