![]() ![]() Elevated JVP is referred to as jugular venous distention (JVD). The normal pulmonary capillary wedge pressure is between 4 to 12 mmHg. Consider diuresis if the following conditions are met: (1) There is significant pulmonary and/or systemic congestion. The pulmonary capillary wedge pressure (PCWP) is considered elevated if >18 mm Hg, and is a sign of fluid overload. Be careful static hemodynamic parameters (e.g., CVP, pulmonary capillary wedge pressure) do not predict fluid-responsiveness and should not be used as the primary determinant of fluid administration. The following tables and graph depict the correlation of bedside-measured jugular venous pressure (JVP) with cardiac catheterization hemodynamics in patient with chronic congestive heart failure. Excerpt Pulmonary capillary wedge pressure (PCWP) is frequently used to assess left ventricular filling, represent left atrial pressure, and assess mitral valve function.

Pleural pressure (black line) shows respiratory swings, which appear transmitted to pulmonary vascular pressures. phase of filling and is within a few mmHg of the mean LAP or PCWP. Pulmonary capillary wedge pressure (PCWP) indicates fluid status patients are classified as either 'dry' or 'wet' depending on the presence of edema, which is defined as a PCWP >18 mmHg. (B) Pulmonary artery pressure (red line) followed by pulmonary artery wedge pressure (arrow) in a patient with chronic obstructive pulmonary disease at rest (left) and during exercise (right). All calculations must be confirmed before clinical use or diagnostic purposes by qualified medical professionals.
