The investigators aim to achieve experts consensus on respiratory interventions in management of COVID-19 related acute respiratory failure (C-ARF). The pandemic of COVID-19 is unique in terms of a multitude of patients suffering from ARF and requiring invasive mechanical ventilation with single underlying inciting etiology.The experts have given divergent opinions on respiratory support of C-ARF which may have confused physicians globally.

The investigators are going to use a modified Delphi based methodology involving global participating experts. The objective is to achieve consensus statement on the management of C-ARF using "collective intelligence".

The whole process of this study will be done in the form of two-three rounds of Google Forms-based Delphi surveys. In this survey questionnaire, the investigators have prepared statements on the concern areas in the respiratory support of C-ARF. The survey has been divided into five sections related to C-ARF management. The majority of these statements are to be rated on Likert scale and others have multiple choices. There is an option for collecting participating experts comments in provided open space in round one which will be considered during round two questionnaire.
