|ARDS, Human Mechanical Ventilation Complication COVID19||Procedure: Prone Positioning Procedure: Standard of care.||Not Applicable|
Prone positioning (PP) is an adjunctive therapy used that has been proven to save lives in sedated patients with confirmed moderate-severe acute respiratory distress syndrome (ARDS) receiving invasive mechanical ventilation (MV). PP involves placing patients in the prone, i.e. face down position for time periods of up to 16 hours per day. PP promotes lung homogeneity, improves gas exchange and respiratory mechanics permitting reduction of ventilation intensity, and reducing ventilator-induced lung injury (VILI).
Maintaining self-ventilation is associated with increased aeration of dependent lung regions, less need for sedation, improved cardiac filling and removes the risk of VILI, and so is an important therapeutic goal in hypoxic patients. The use of PP in awake self-ventilating patients with COVID-19 induced acute hypoxic respiratory failure (AHRF) and/or ARDS could improve gas exchange and reduce the need for invasive MV, but has not been studied outside of case series.
However, an increase in oxygenation does not necessarily reduce the risk of invasive MV. PP has significant attached risks such as causing pressure sores in patients, PP is uncomfortable for some patients, it increases nursing workload, and if ineffective could hinder the delivery of other (effective) medical care. Hence there is a need to determine if PP of awake patients is effective in reducing the need for invasive MV. This multi-centre, open label, randomized controlled study of COVID-19 induced AHRF/ARDS will determine if PP reduces the need for mechanical ventilation.

Experimental: Prone Positioning
Intervention patients will remain up to 16 hours per day in Prone Positioning with 45 minutes breaks for meals
Procedure: Prone Positioning
Patient will be asked to remain for at least one hour and to a maximum total of 16 hours in prone position with 45 minutes breaks for meals. Immediately prior to proning, if spO2 <94% on FiO2 0.4, start on 100% O2 to ensure stability during proning. A nurse or assistant will assist patient to turn on side and then face down with the support of pillows as required for comfort, ensure that they are predominantly on their chest rather than on their side. Arms can be at side, in swimmer position and can be moved to patients' comfort, pillows under knees and chest for comfort and call bell to be at patient's arm's length. Vitals and work of breathing score will be measured before and at 1 hour into each proning session and at the end of each session. Total length of time in prone position will be recorded. Intervention to continue daily until oxygen requirement to maintain spO2 >94% is below FiO2 0.4 via venturi facemask or high flow nasal cannula
Active Comparator: Standard Care
Control patients will receive full standard care. Prone Positioning as a rescue intervention is permitted and is recorded.
Procedure: Standard of care.
Standard of care. Prone positioning may be administered as a rescue therapy
