What would the hemodynamic assessment show for a patient with a Pulmonary Embolism?

In the case of a pulmonary embolism (PE), the hemodynamic assessment would show an increase in pulmonary artery pressure (PAP). This is primarily due to the obstruction of blood flow in the pulmonary arteries caused by the embolus, which can result in increased resistance to blood flow. The right ventricle must work harder to pump blood through the narrowed or blocked pulmonary vessels, leading to elevated pressures in the pulmonary artery.

As a consequence, patients with a pulmonary embolism often demonstrate elevated PAP on hemodynamic monitoring. This increase in pressure can vary depending on the size of the embolism, the pre-existing pulmonary vascular resistance, and the overall hemodynamic status of the patient, but typically, a significant obstruction will result in an increase in PAP.

Understanding this response helps in diagnosing and managing the condition, as well as recognizing the implications of elevated pressures in relation to a patient’s overall cardiovascular function.
