About

The pathophysiology of SARS-COV-2 related respiratory disease is still poorly understood, especially in its most severe form called acute respiratory distress syndrome (ARDS). In this case, very few studies have investigated changes in gas exchange during COVID-19 progression in spontaneously breathing patients. The investigators purpose in this study to explore the pathophysiology of gas exchange and time course changes in spontaneously breathing patients with acute respiratory failure due to COVID-19. Moreover, our aim is to identify early markers associated with worsening respiratory failure and requiring endotracheal intubation.
