Primary Outcome Measures

Name	Time	Method
Protocol Compliance: the proportion of participants who receive their assigned intervention and do not ‘cross-over’ (e.g. receive a pulmonary artery catheter if assigned to the control group), ascertained from the electronic medical record.[After randomisation occurs until first discharge from the intensive care unit.]
