Design and prototyping of monitoring system for Asthma patient

Abstract

In both children and adults, asthma is a chronic disease of the respiratory system that affects lung function and results in breathing problems because it narrows and inflames the airways. Even though it cannot be cured, the appropriate strategy and action plan can help in managing it. To properly treat asthma, self-management is a crucial component. Vital signs need to be checked frequently for people who have chronic illnesses. Digital monitoring gadgets that warn users of impending asthma attacks have been created thanks to improvements in health technology. These monitoring systems enable access to data so that it may be transmitted to a personal device, or clinicians follow up and appropriately record the time of each monitoring session that the patient performs it. This study offers real-time monitoring based on an IoT system, which is utilized to measure the values of the patients' body temperatures, heart rates, oxygen saturation, and body temperatures as the most important measurements required for critical care. It has been noted that outdoor environmental factors, such as air pressure, humidity, and temperature, can cause asthma attacks and cause various asthmatic symptoms. The proposed system will track body temperature, heart rate, and oxygen saturation. It will also employ an ambient sensor to track changes in temperature, humidity, and air quality that might trigger asthma episodes when they are outside of the ideal range. The prototype monitoring system is equipped with pressure, temperature, humidity, and pulse oximeter sensors. The pulse oximeter sensor is applied to the finger, and it simultaneously measures the patient's pulse rate and oxygen saturation levels in asthmatic patients. After that, the microcontroller collects the data from the pulse oximeter and sends it over Wi-Fi and a cloud database to the GSM module, where it is displayed on the LCD. Information could be accessed online via a web-based application. When a measurement from the sensor exceeds a threshold value, the system was sent SMS alarm notifications via GSM to caregivers or doctors
