WebIntroduction: Right ventricular (RV) systolic dysfunction is common in acute respiratory distress syndrome (ARDS). While preload optimization is crucial in its management, dynamic fluid responsiveness indices lack reliability, and there is no consensus on target central venous pressure (CVP). Web31 de ago. de 2024 · Since the filling pressure and LVSV of the RV do not have a linear relationship, it has recently been acknowledged that CVP is ineffective for evaluating a patient's fluid responsiveness (27–29). While the absolute value of CVP alone cannot predict fluid responsiveness, it is necessary to understand that CVP is a marker of pressure and … WebNormal RV systolic pressure is 20–30 mmHg and normal diastolic pressure is 3–7 mmHg (Table 2).
