5)PROJECT DETAILS
1. INTRODUCTION:
Human lungs use the reverse pressure generated by contraction motion of the
diaphragm to suck in air for breathing. A contradictory motion is used by a ventilator to inflate
the lungs by pumping type motion.
A ventilator mechanism must be able to deliver in the range of 10 – 30 breaths per
minute, with the ability to adjust rising increments in sets of 2. Along with this the ventilator
must have the ability to adjust the air volume pushed into lungs in each breath. The last but
now the least is the setting to adjust the time duration for inhalation to exhalation ratio.
Apart from this the ventilator must be able to monitor the patients blood oxygen level
and exhaled lung pressure to avoid over/under air pressure simultaneously.
The ventilator we here design and develop using arduino encompasses all these
requirements to develop a reliable yet affordable ventilator to help in times of pandemic.

3. We here use a silicon ventilator bag coupled driven by DC motors with 2 side push
mechanism to push the ventilator bag. We use toggle switch for switching and a variable pot
to adjust the breath length and the BPM value for the patient.
Our system makes use of blood oxygen sensor along with sensitive pressure sensor to
monitor the necessary vitals of the patient and display on a mini screen. Also an emergency
buzzer alert is fitted in the system to sound an alert as soon as any anomaly is detected.
The entire system is driven by arduino controller to achieve desired results and to assist
patients in pandemic and other emergency situations.
2. OBJECTIVE :
The objective of building a ventilator using Arduino with blood oxygen sensing for the
pandemic is to create a low-cost and accessible solution to assist individuals with severe
respiratory distress caused by the virus. Ventilators are critical medical devices used to support
patients who have difficulty breathing or have respiratory failure. Given the potential shortage
of ventilators during a pandemic, especially in resource-constrained settings, solutions like this
can be a valuable emergency alternative.
Here are the main objectives of such a project:
Patient Respiratory Support: The primary goal is to develop a functional ventilator
that can assist patients with severe respiratory issues by delivering controlled and monitored
airflow to their lungs. This can help save lives in situations where traditional ventilators are in
short supply.
Low-Cost Design: Make the ventilator as affordable as possible, using readily
available components, especially considering the cost constraints faced during a pandemic.
Arduino-Based Control: Utilize Arduino or other open-source microcontroller
platforms to control the ventilator's operation. Arduino offers flexibility, ease of programming,
and a wide range of sensors and actuators that can be integrated into the design.
Blood Oxygen Sensing: Incorporate blood oxygen (SpO2) monitoring capabilities into
the ventilator to provide real-time feedback on the patient's oxygen saturation levels. This is
crucial for assessing the patient's condition and making necessary adjustments to the ventilation
settings.
Safety: Ensure the design prioritizes patient safety. Implement features like alarms for
critical conditions, pressure sensors to prevent over-inflation of the lungs, and fail-safes to
protect against malfunctions.
User-Friendly Interface: Develop a user-friendly interface for healthcare
professionals to set and monitor ventilation parameters, view SpO2 readings, and receive alerts
when necessary.

4. Documentation and Open Source: Document the design, code, and build process
thoroughly to allow others to replicate the ventilator. Open-source the design to encourage
collaboration and improvements from the maker and medical communities.
Compliance and Testing: Ensure that the ventilator complies with relevant medical
and safety standards to the best extent possible. Conduct thorough testing and validation to
confirm its effectiveness in providing life-saving respiratory support.
Scalability: Design the ventilator with scalability in mind, allowing for mass
production if necessary.
Emergency Use Only: Emphasize that the ventilator is intended for emergency use
when standard medical-grade ventilators are not available. It should not replace professionally
manufactured and certified medical devices.
Collaboration with Medical Professionals: Collaborate with healthcare professionals
and authorities to ensure that the ventilator aligns with medical guidelines and can be safely
used in clinical settings.
Public Awareness and Education: Raise awareness about the ventilator project within
the maker and medical communities. Provide training and educational resources to ensure
proper use and maintenance.
3. METHODOLOGY :
Plan the overall design and layout of your ventilator, considering factors like size,
portability, and ease of use.
Develop a circuit diagram and schematic for the electronic components.
Choose appropriate sensors and actuators and design their integration into the system.
Define the control algorithm that will regulate the ventilation parameters (e.g., tidal
volume, respiratory rate).
Incorporate safety features such as pressure relief valves, alarms for critical conditions, and
a fail-safe mechanism..
Assemble the physical components, including the mechanical structure, sensors, actuators,
and display.
• Connect and integrate the electronic components according to the circuit diagram.
• Conduct initial functional tests to ensure that the system operates as expected.
• Test the ventilation modes with a test lung or a simulated respiratory system.
• Perform calibration and sensor validation to ensure accurate readings.
