Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.

In crude terms, this measurement compares left and right cardiac activity and calculates preload and afterload flow and pressures which, theoretically, can be stabilized or adjusted with drugs to either constrict or dilate the vessels (to raise or lower, respectively, the pressure of blood flowing to the lungs), in order to maximize oxygen for ...
Right atrial pressure (RAP) is the blood pressure in the right atrium of the heart.RAP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood into the arterial system.
Considering that heart disease is the leading cause of death in the U.S., taking good care of your heart is pretty darn important. Much of being proactive about heart health comes down to diet and ...
Only those patients whose mean pulmonary artery pressure falls by more than 10 mm Hg to less than 40 mm Hg with an unchanged or increased cardiac output when challenged with adenosine, epoprostenol, or nitric oxide are considered vasoreactive. [70] Of these, only half of the patients are responsive to calcium channel blockers in the long term. [71]

Pulmonary barotrauma is lung injury that results from the hyperinflation of ...
