The message was that management of SARS-CoV-2 lung disease needed to be guided strictly according to established dogma in acute respiratory distress syndrome unless supplanted by clinical trials specific to COVID-19. This position is predicated on the assumptions that knowledge about acute respiratory distress syndrome, and only about that entity, is directly translatable to SARS-CoV-2 lung disease, and that clinical trials enrolling COVID-19 patients will be completed in a sufficiently timely and rigorous fashion to influence empirical practice during the current pandemic. Clearly, there is room for an alternative perspective. In this Viewpoint, we aim to articulate a contrary point of view by resorting to arguments that are likely to resonate with frontline clinicians battling COVID-19.It is debatable whether existing evidence-based principles for the management of acute respiratory distress syndrome are sufficiently applicable to #SARSCoV2 lung disease to serve as strict dogma for the approach to this novel clinical entity https://bit.ly/2XjYPQs
