Episode notes
PE Terminology
- Pulmonary embolism (PE) can be broadly used for all embolic events (blood clots, air, fat, amniotic fluid).
- Colloquially, PE often refers specifically to thromboembolic events from lower extremities.
PE Pathophysiology
- A PE increases dead space, leading to hypercarbia and hypoxemia, increased pulmonary vascular resistance, and acute pulmonary hypertension.
- Right heart failure can occur in susceptible patients, and if bronchial circulation doesn't compensate, a pulmonary infarct may result.
Exam Focus: Right Heart Failure
- Focus on right heart failure as a common PE presentation, especially on exams.
- Understand specific echo findings for right heart failure, not just its presence.
