    Bypass Flow Improvement in Pneumatically Driven Mechanical Blender Centric Ventilators
    Author(s): Darla Mani Sai Kamal* and Venugopal P G

    Manufacturing ventilators for intended applications is always an exacting task as the requirements keep changing. The pneumatically driven ventilators have an internal blender which requires minimum pressure to operate. The balancing mechanism, bypass flow paths do not support high flow demands for extreme patient conditions. In order to address this issue, improvements in the concept of mechanical blending has been made to reduce the usage of electronics. During the tough times of Covid-19, the ventilators manufactured in large numbers should meet all extreme cases. The power consumption needs to be minimum and patient demands during portable conditions have to be met. So, the challenges faced to maintain the pressure of blended gases in the ventilator system and also incorporation of external bypass valve are discussed in this paper... View More»
