Association of central venous pressure with intra-abdominal pressure, mean airway pressure and hemodynamics: an observational study

Central venous pressure (CVP) is frequently used to guide fluid therapy, although there are confounders of CVP like intra-abdominal pressure (IAP) and mechanical ventilation. Despite a large number of studies on the interactions of intra-abdominal pressure, mechanical ventilation and CVP there are few studies investigating the impact of both major confounders of CVP in the same setting.
