This study is focussed on the design and modelling of a low-cost ventilator design that can be developed using locally sourced materials in Nigeria. This is meant to aid in the country's fight against the current COVID-19 pandemic where there is a shortage of ventilators. The ventilator design in this research was based on a mechanical AMBU bag compression principle using the volume-control ventilation (VCV) mode, which will eliminate the need for manual compression, which can be tedious and uncontrolled. The design is powered by an electric motor with variable speed and tidal volume control. It also features an alarm that alerts medical personnel of unstable conditions in the system parameters. This prototype shows that the mechanical compression systems is a viable and more economical option that provides the essential features required in the standard existing technologies.
