Pulmonary Embolism Suspected : Triage

Pulmonary embolism (PE) stands as a significant medical concern, positioned as the third leading cause of cardiovascular mortality. This condition arises when a blood clot, typically originating from deep vein thrombosis (DVT) in the lower extremities, travels through the bloodstream to occlude the pulmonary arteries. The primary consequence of this obstruction is the potential for acute right ventricular (RV) failure, which poses a severe risk to life due to the heart's diminished ability to pump blood efficiently through the lungs for oxygenation.
