Fluid responsiveness and changes in venous congestion and lung water during volume expansion in critically ill patients: a multicentre observational study

Key Points

• This study aims to understand the effects of volume expansion on venous congestion and fluid responsiveness in critically ill patients.
• Conducted a multicentre observational study
• Monitored venous congestion using VExUS and CVP assessments
• Categorized patients into fluid responders and non-responders
• Fluid challenge worsened venous congestion in non-responders
• No worsening of venous congestion observed in fluid responders
