In the case of right ventricular (RV) dysfunction or failure, which changes are expected?

In cases of right ventricular dysfunction or failure, it is typical to observe an increase in central venous pressure (CVP) due to the inability of the right ventricle to effectively pump blood into the pulmonary circulation. This results in venous congestion, leading to elevated pressures in the venous system, which is reflected in a higher CVP.

Additionally, the systemic blood pressure generally decreases due to the overall decline in cardiac output. The heart's failure to pump blood efficiently causes less blood to flow into the systemic circulation, thus reducing systemic blood pressure.

In summary, the correct changes associated with right ventricular dysfunction include decreased systemic blood pressure coupled with increased central venous pressure. This understanding is critical for identifying the physiological impact of right ventricular issues on the circulation and in guiding clinical management for patients exhibiting these signs.
