In lung ultrasound, pulmonary embolism (PE) signs are crucial for rapid diagnosis of this life-threatening condition. Key indicators include the absence of lung sliding, the presence of B-lines (indicating interstitial edema), and often, signs of right ventricular strain. The “POCUS” approach for PE evaluation rapidly assesses the heart and lungs, looking for these sonographic clues.
Identifying these signs via ultrasound helps clinicians quickly assess for PE, especially in unstable patients where traditional imaging might be delayed. Early detection of features like right heart overload or specific lung findings allows for prompt initiation of life-saving treatment, highlighting ultrasound’s role in critical care and emergency medicine.
