AUTOMATED AMBULANCE DISPATCH SYSTEM USING MACHINE LEARNING ALGORITHMS

Abstract

Abstract One essential part of emergency medical services that strives to minimize response times and save lives is the Automated Ambulance Dispatch System (AADS). To improve the precision and timeliness of ambulance dispatches, we present a new method that makes use of machine 5 learning techniques. To train predictive models, the system makes use of past data from emergency calls, which includes the time, location, and severity of instances. To determine the best way to deploy resources in an emergency, we use a variety of machine learning methods. By integrating and analysing data in real-time, dispatch choices may be dynamically adjusted for changing situations such medical resource availability and road 10 congestion. The conventional rule-based dispatch systems after rigorous testing in both virtual and real-world emergency situations. It helps improve patient outcomes in life- threatening circumstances by demonstrating faster response times, more efficient use of resources, and overall performance of emergency medical services.

Specification

The automated ambulance dispatch system, which uses machine learning, combines many sectors to improve emergency medical care. It determines the most effective ambulance dispatch, by analysing real-time data such as patient and ambulance geolocation, traffic 5 conditions, weather, and emergency severity. Machine learning algorithms are used to analyse historical data, forecast ambulance arrival times, and choose the best route depending on traffic patterns and the urgency of the case. The algorithm also considers ambulance availability, dispatching the nearest and best-equipped vehicle. IoT devices collect data from ambulances and patients, and cloud computing analyses and stores massive amounts of data 10 to enable speedy decision-making. This combination of machine learning, real-time data, and modem technology allows for shorter reaction times, more efficient resource allocation, and better patient outcomes by assuring immediate medical intervention. The system is intended to improve the efficiency and dependability of emergency response, eventually saving lives and optimising healthcare resources.


Background of Invention
The automated ambulance dispatch system was developed in response to the rising need for more efficient emergency medical services (EMS). Traditionally, ambulance dispatch depended on manual methods, which often resulted in delays owing to road congestion, 5 inefficient routing, or insufficient resource allocation. As cities grow in population and healthcare needs rise, there is a clear need for a smarter, more automated solution. Using machine learning and IoT technologies, this system aims to solve these difficulties by optimising ambulance dispatching in real time. Machine learning algorithms can forecast the most effective response times and routes by analysing massive quantities of previous EMS 10 data, such as traffic patterns, ambulance availability, and patient status. This allows for faster and more accurate dispatching. Predictive modelling enables the system to dynamically adapt to changing situations, such as unexpected traffic congestion or medical problems that need special attention. The combination of GPS with cloud computing allows for continual updates and centralised data administration, making the system more adaptive and scalable. This 15 method not only decreases response times, but it also improves overall healthcare delivery, patient outcomes, and EMS resource utilisation.


Object of Invention • Raspberry Pi • Temperature Sensor • Blood Pressure sensor 5 • Motion Sensor • .Ambient Light Sensor

The system initiates the collection of real-time health data via a network of sensors embedded in wearable or portable devices. The temperature sensor monitors body temperature to identify anomalies such as fever or hypothermia, whilst the blood pressure sensor continually 5 - assesses blood pressure levels to detect indications of hypertension or hypotension. The motion sensor identifies patient movement, facilitating the evaluation of their physical state, including consciousness or immobility. Simultaneously, the ambient light sensor assesses the illumination levels in the vicinity, which may signify an emergency, such as an incident in a dimly lit or inadequately illuminated setting. Collectively, these sensors provide an extensive 10 perspective on the patient's health and environment, enabling prompt action when required.
The Raspberry Pi functions as the edge computing device in this system, essential for real­time data processing. It aggregates data from several sensors and does preliminary analysis on-site, eliminating the need for constant online connectivity. The Raspberry Pi can promptly evaluate whether the temperature sensor readings exceed or fall below typical levels, 15 activating an alarm if the patient's temperature is too high or low. It can likewise analyse blood pressure measurements from the sensor to identify problems such as hypertension or hypotension. This early analysis enables the Raspberry Pi to facilitate swift decision-making, minimising reaction time and assuring fast attention to important health problems. Upon analysing the data, the Raspberry Pi transfers the results to a centralised cloud system for 20 further action, facilitating a smooth transition between local data processing and worldwide
coordination.
After local data processing, the Raspberry Pi interfaces with a centralised cloud-based dispatch system by wireless communication protocols, such Wi-Fi or Bluetooth. The cloud system then analyses the sensor data more thoroughly, considering many parameters like 25 traffic conditions, ambulance availability, and patient health. The cloud-based machine learning algorithms evaluate the emergency's severity using sensor data, such as irregular blood pressure or absence of movement, and forecast the optimal response. Should the motion sensor ascertain the patient's unresponsiveness, the system may prioritise an expedited reaction. The ambient light sensor may signal if the patient is in a low-visibility 30 region, indicating the need for specialised routing considerations. The interaction between the Raspberry Pi and the cloud system guarantees the availability of the most precise and current information for optimal ambulance dispatch decisions.


After the data is analysed by the cloud system, the Automated Ambulance Dispatch System employs machine learning algorithms to choose the most suitable ambulance for dispatch.
This choice considers factors like the ambulance's closeness to the patient, the available medical equipment, and the skill of the team. The device analyses traffic data to identify the most expedient path to the patient, avoiding congested zones to guarantee punctual arrival.
For example, if the blood pressure sensor signals a major cardiovascular emergency, the system may prioritise an ambulance outfitted with advanced life support (ALS) equipment.
The amalgamation of real-time data processing with machine learning guarantees that every ambulance dispatch relies on the most pertinent, current information, hence enhancing the efficiency and efficacy of emergency medical services.
The system consistently observes the patient's condition throughout the dispatch procedure.
The sensors remain operational, relaying data to the Raspberry Pi and then to the cloud system for continuous analysis. Should the patient's condition alter-such as a deterioration in blood pressure or temperature-the system might revise the dispatch choice appropriately.
For instance, if the temperature sensor identifies a substantial change in the patient's state, the ambulance personnel might ready themselves for specialised treatments, such as using cooling or heating apparatuses. The motion sensor consistently delivers information about the patient's physical condition, notifying paramedics if the patient becomes unresponsive or unstable. This constant flow of data guarantees that paramedics arrive well equipped, with the latest knowledge on the patient's health condition, hence facilitating prompt and precise treatment. The system's capacity for real-time updates significantly augments its efficacy in crucial scenarios, hence enhancing patient outcomes and the overall standard of care.


Detailed Description of Invention
The system is a great fit for the little and reasonably priced Raspberry Pi single-board computer. Raspberry Pi can manage data processing, communicating with servers or databases, and connecting to several sensors with ease because to their robust processing capabilities, large memory, and numerous connection choices such as HDMI, USB, Ethernet, and GPIO pins. It is the perfect platform for implementing the complex features needed to optimize ambulance dispatch and response, thanks to its Linux-based operating system, which allows for flexible software development and integration.
The temperature sensor takes constant readings of the ambulances inside temperature. The ability to quickly identify individuals experiencing symptoms of hypothermia or fever depends on these data. The device enables early diagnosis of potentially life-threatening illnesses by monitoring temperature levels. This allows appropriate actions and optimizes patient care. The system's capacity to properly evaluate the patient's health state is improved by integrating data from temperature sensors with readings from other sensors, leading to better results in emergency medical scenarios.
An essential part of the AADS is the blood pressure monitor, which keeps tabs on patients' vitals all the time. To evaluating medical crises and prioritizing dispatches, this data gives vital insights into patients' health state. Timely medical interventions and optimal resource allocation are ensured by continually monitoring blood pressure, which allows the system to prioritize responses to high-risk situations. By combining data from many sensors, including blood pressure monitors, the system may better prioritize patients in life-threatening circumstances, leading to better results for patients.
Ensuring the safety and well-being of patients and medical professionals during travel, the motion sensor detects movement inside the ambulance. The device can always detect movements in the car and notify medical personnel of any disruptions or crises so that they can respond quickly. Better patient outcomes in life-threatening circumstances are a direct result of this capability's capacity to reduce transportation-related hazards and guarantee the prompt provision of medical treatment.
The ambient light sensor determines the amount of light inside the vehicle. To provide the best possible visibility for medical operations and patient care, this data is essential for altering lighting settings. The technology may keep patients and medical staff comfortable by automatically adjusting the interior lighting based on the measured levels of ambient light
