The COVID-19 pandemic has affected more than 20 million people worldwide with a death toll of over 700 thousand. Continuous Positive Airway Pressure (CPAP) therapy is known to reduce the need for mechanical ventilation (MV) in treating hypoxic COVID-19 patients. We present OxyJet CPAP, an electricity-free low-cost noninvasive positive pressure ventilation (NIPPV) system specifically designed for low and middle-income country (LMIC) hospitals. It can provide a 20cm H2O positive end-expiratory pressure (PEEP), peak inspiratory flow-rate up to 65 liters/min (LPM), and a fraction of inspired oxygen (FiO2) of up to 95%. The device utilizes the mechanics of a jet pump driven by high-pressure oxygen to increase the volumetric flow rate by entraining atmospheric air. We use a snorkeling mask (as helmet/hood) to deliver CPAP therapy to reduce aerosolization risk. Although High Flow Nasal Oxygenation (HFNO) is effective in treating severe COVID-19 patients, it is too expensive for public…
