for >4hr such as extended airplane or vehicle ride), high-altitude exposure, genetic
predisposition.

Signs and Symptoms:
1. Asymmetric pain and swelling in a lower extremity (often the calf muscles)
2. Warmth and ↑ pain in affected calf muscles on dorsiflexion of foot (Homans’ Sign)

Management:
1. Monitor patient with SpO2, sudden decrease in SpO2 suggests a pulmonary embolism
2. ASA 325mg PO
3. If sudden chest pain or respiratory distress occurs, consider pulmonary embolus and administer
oxygen if available
4. Immobilize the affected extremity

DISPOSITION:
1. Priority evacuation if no respiratory distress or chest pain.
