Portable ventilator

Project Title

Portable ventilator

Project Area of Specialization Biomedical EngineeringProject Summary

The current COVID-19 pandemic has heavily impacted the healthcare system in the Pakistan and elsewhere. The need for patients to have access to a hospital with a ventilator along with a shortage of ventilators for recovery and at-home care as a result of minimal hospital vacancy for patients has been greatly stressed. The presented problem is both an unmet demand and supply of portable and effective ventilators. Existing ventilators have many shortcomings that should be addressed: size, weight, cost, and complexity of current ventilators confines users to stay in a medical facility whilst being monitored by professionals. This both increases the risk the user has of contracting other diseases and increases the cost to operate a ventilator. Therefore, there is a need to create a ventilator that is both smaller and more accessible than what is currently available

Project Objectives

The Portable Ventilator is a mechanical ventilation device designed to tackle one of the biggest problems with current ventilators, their restrictiveness. Currently patients are required to either be hospitalized and occupy an ICU room risking contracting disease or forgoing care. This leaves many patients with milder symptoms to have two bad options. Along with this, hospitals are also at a loss. Every patient with milder symptoms that is hospitalized is one less ICU room available for other patients with more severe symptoms. This also puts a strain on the limited resources hospitals have, such as nurses, since the ventilator must be constantly monitored and adjusted.The Portable Ventilator seeks to solve these problems by providing a third option to patients and hospitals. This is the ability to provide out-patient care for mild cases that require help breathing and oxygen intake. This would be done by designing the Portable Ventilator to be lighter, smartphone compatible, automatic monitoring and adjustment, and a simpler interface for controlling the device. This would allow the ventilator to be used at the patients home with no need for professional monitoring. This would meet both the patient’s need to be provided care without hospitalization and the hospital’s need to keep available rooms and staff.

Project Implementation Method

Ventilators are controlled by microprocessors. These microprocessors are responsible for controlling and communicating with various components. These components include the sensors, compressors, pumps, displays, and etc. For the Portable Ventilator design we would need a microprocessor that can perform those same duties using I2C communication protocol along with having wireless capability. A Esp 32 microprocessor is capable of this[8]. The sensors needed are many, with flow rate, temperature, humidity, and O2 being a few. There are many available sensors that could be used which are both small and require little power.

Benefits of the Project

More patients have access to medical care

Cost-Efficiency: Doctors and nurses are only seeing the most symptomatic patients in person, which means more hospital rooms available and time being spent more effectively.

Outpatient Care
