Low-Cost Wearable Asthma Monitoring System with a Smart Inhaler

Asthma is a lifetime chronic disease that leads to abnormality of lung functions and difficulty in breathing. It is one of the most widespread chronic diseases which causes breathing problems and abnormal functionality of the lungs. It is a condition where the airways tend to swell and produce excess mucus. The symptoms of asthma include shortness of breath, tightness in the chest, wheezing sound when breathing specifically found in kids, tiredness, etc. It has been observed that cases of asthma are increasing day by day due to pollution in the air and exposure to unfavourable conditions. This proposed health monitoring system continuously monitors the patient's heartbeat and his/her external environment conditions. The system includes sensors to sense all the external parameters like humidity, heartbeat, smoke, and temperature, it will also measure the temperature of the person wearing the band. All these parameters will be sensed and are uploaded to the cloud server which is accessible to the doctor and caretaker through an application. An alert message is also sent to the patient if the system detects an unfavourable asthmatic environment. This helps the patient to keep track of his asthma and avoid an unnecessary asthmatic attack. Both the monitoring device and smart inhaler focuses on the treatment of asthma by improving overall lung function, reducing daily symptoms and preventing acute asthma attacks.
