Mortality due to Acute Respiratory Distress Syndrome secondary to COVID 19, using the formula adjusted for the height of Berlin in the city of Bogotá

Berlin consensus (2012) defined ARDS as an oxygenation disorder with PaO2/FiO2 < 300, associated with a triggering event in the previous 7 days, with diffuse alveolar infiltrates, not fully explained by heart failure, with Positive Pressure at expiratory (PEEP) of at least 5 cmH2O. This definition is applicable to places with an altitude < 1000 meters, and the consensus gives a recommendation to adjust the PaO2/FiO2 based on the result of the Barometric Pressure (Pb) of the determined place above 760 mmHg (Pb at sea level), This recommendation does not have bibliographic references, evidencing the lack of studies on the behavior of ARDS at altitude. This study seeks to answer the question: What is the incidence of ARDS due to COVID 19 at the Mayor Méderi university hospital located 2600 meters above sea level? sea ​​level and what are the oxygenation indices at altitude that correlate with levels of severity and expected mortality at sea level?
