Introduction
Ventilators are one of the most important devices to keep COVID-19 patients in the most critical condition alive. As the global demand for ventilators is increasing and there is
shortage of ventilators in our country as well, also managing patients during this time is a big task, so we have designed portable rechargeable battery operated Ambu bag
compressing machine, which sends real time cloud messages to the doctors and other medical authorities about the patient. We have made the prototype and we are improving
it's performance by adding extra new features. It can be used for emergency purposes, in hospitals, Corona virus quarantine coaches, isolation wards and rural areas as well. The
shortage of ventilators can be met effectively by developing this project. This project is a low cost yet effective ventilating system for the people affected with COVID-19.

Survey
Objectives
Abdul Mohsen Al Husseini et
al., [1] Designed and made a
prototype of low cost portable
mechanical ventilator for use
in mass casually cases and
resource poor environments.
The ventilator compresses
Bag Valve Mask (BVM) with
cam arm to deliver breaths,
this system eliminates human
operator for compressing
BVM. They developed
working prototype with assist
control and over pressure
alarm, they system needs low
power requirements and runs
for 3.5 hours on single battery
charge.

Introduction
Objectives
Methodology
Objectives
1. To meet the increasing
demand of mechanical
ventilators due to COVID-19.
2. To provide low cost alternative
to ventilators.
Problem Definition
Based on survey it is found that there is a
need of affordable Low cost ventilators in
India to fight against COVID-19, also
managing patients during this time
challenging task and it is intended to
develop a low cost Smart Ambu-Bag
Compressing Machine for Low Cost
Ventilators
Objectives
3. To develop a very easy to
operate system so that any less
experienced person must be able
to operate it with ease.
4. To develop a cloud based
patient management system to
handle patients of COVID-19.

Introduction
Working
Features
The Ambu-Bag compressing mechanism is operated with a stepper motor which is connected to MSP430 microcontroller which acts as brain of the
system. 15Watt solar panel is used to charge the battery which is beneficial at rural places, army and trucking camps. The microcontroller is in
serial communication with the Wi-Fi module to connect with the internet and access real-time patient requests from the cloud. We have developed
user friendly android application with which the doctors and other authorities can easily monitor the patient requests. The degree of compression
and the output air pressure can be controlled by adjusting potentiometer knob provided on the machine. Button with extendable wire is provided for
the patients if the patient wants to call the doctor he can use this button, on press of a button the buzzer will create sound so that if the doctor is
nearby he can respond the patient request also the system will send automatic cloud messages if the doctor was unable to hear the sound for some
reason, if there is any technical problem in the system the buzzer will create a sound of different frequency.

Outcomes
References
1. This system is useful while shifting patients from ICU or home to ambulance or if needed at any
accident site.
2. It helps persons who perform first aid by systematic easy approach, even less experienced persons
can easily operate it.
3. Battery can be charged by solar or mains “solar power for remote locations like army or trucking
camps”.
4. Easy to reprogram if any changes are required in the system.
