Abstract
The COVID-19 pandemic has created worldwide intense development of low cost solutions to provide mechanical ventilator devices. Despite the diverse alternatives, the equipment is complex and relays on sensors and valves to adjust and maintain the proper pressure, oxygen saturation and other parameters critical to help and also to avoid damage to the lungs. In this context, an initiative from Jet Propulsion Laboratory (JPL-NASA, USA) provided a low cost ventilator design that avoided components that are commonly used in the production of traditional ventilators. Despite the lower cost, there were also restrictions found in the supply chain on some of the components of the ventilator. This work presents the design alternative to reduce the dependency on importing flow sensors and integration to other components inside the VITAL Mechanical Ventilator developed by JPL team. The design change kept the principles of the original Design but it improved integration of the components, local manufacturing, reduction of components, improved internal space and made maintenance easier.
