WebPathophysiology. Normal pulmonary artery systolic pressure at rest is 18 to 25 mm Hg, with a mean pulmonary pressure ranging from 12 to 16 mm Hg. This low pressure is due to the large cross-sectional area of the pulmonary circulation, which results in low resistance. 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 …
