Changes in central venous-to-arterial carbon dioxide tension induced by fluid bolus in critically ill patients.

Changes in central venous-to-arterial carbon dioxide tension induced by fluid bolus in critically ill patients.

<h4>Background</h4>In this prospective observational study, we evaluated the effects of fluid bolus (FB) on venous-to-arterial carbon dioxide tension (PvaCO2) in 42 adult critically ill patients with pre-infusion PvaCO2 > 6 mmHg.<h4>Results</h4>FB caused a decrease in PvaC...
