Abstract

This paper presents the construction of a low-cost, open-source mechanical ventilator. The motto behind making this type of ventilator comes from the global shortage of ventilators to treat patients suffering with Covid-19. This paper presents a digital method to monitor the lung status of patients. This is achieved by determining pressure measurements from the inspiratory arm and alerts clinicians if the patient is in a healthy or unhealthy condition. The common symptoms of Covid-19 that can be easily identified are body temperature, blood oxygen level and heart rate that we must check to identify the virus. Hence this system can help in case a patient is unable to meet the doctor or requires frequent monitoring. These are going to develop a system which can monitor, and all the monitored data is stored in the cloud. When people suffer from breathing problems, this can be used for emergencies. The ventilator will be able to monitor the patient's blood oxygen levels and exhaled lung pressure while avoiding high pressure. Designed using Arduino, the ventilator meets all these requirements, creating an affordable ventilator to help during a pandemic. A motor mechanism is used to push the air bag. When the oxygen level counts are low, this mechanism is utilized. LCD screens are used to display oxygen levels. Whenever a patient faces a dangerous position, a buzzer sounds to notify a nearby caretaker. The entire system is driven by an Arduino microcontroller and a buzzer is fitted to detect any low levels of oxygen count.
