The ApolloBVM is an automated bag valve mask (BVM) device utilizing off-the-shelf components to provide safe and continuous hospital-grade mechanical ventilation for COVID-19 patients on an open-source basis.The ApolloBVM is a controllable, automated add-on solution to the existing and widely available Bag Valve Mask. The device compresses the BVM with a mechanical system that is able to provide consistent and accurate ventilation with positive-pressure.This solution exists within the top range of high-acuity limited-operability (HALO) ventilator solutions with an a prior design to produce volume and pressure cycled ventilation that includes positive end-expiratory pressure(PEEP) and enriched oxygen sources.Controls of the ApolloBVM are familiar and clinician- designed with adult, child, and pediatric settings. They allow for tailored ventilation, adjustable I:E ratios, and variable positive pressure. Please note: This design took inspiration from the 2018-2019 Rice University Senior Design Project from Team Take A Breather.For updates and access to the Arduino program files please visit http://oedk.rice.edu/apollobvmThe tolerance gauge is a tool to get a sense for how your 3D printer is printing compared to ours. There is a star on the size that your 1/4" steel dowel should slide easily through, but not have any wobble to it. If you find that your steel dowel is fitting correctly in bigger holes, then you may need to modify those files to increase the size of the hole/cavity.
