Practice of Fluid Therapy in Critically Ill Invasively Ventilated Patients

The goal of this woldwide observational study is to investigate various aspects of fluid and vasopressor therapy in critically ill invasively ventilated patients. The main questions it aims to answer are: * What is the global current practice of fluid and vasopressor therapy? * What are associations between this practice and clinical outcomes? Participating intensive care units will gather detailed information about fluid and vasopressor therapy prescribed to participants. Participating intensive care units will also gather information about participant outcomes such as duration of invasive ventilation, length of stay and mortality
