Obstructive shock

Obstructive shock in critical care is a life-threatening condition where blood flow is severely impeded due to an extracardiac obstruction, despite adequate intravascular volume. Common causes include pulmonary embolism, cardiac tamponade, tension pneumothorax, and severe aortic stenosis. Rapid identification through medical ultrasound is crucial for guiding immediate interventions, such as pericardiocentesis or needle decompression, to alleviate the obstruction and restore circulation.

Ultrasound in obstructive shock is vital for point-of-care assessment, allowing clinicians to visualize the heart, lungs, and great vessels for signs of obstruction. Early diagnosis and targeted treatment improve patient outcomes in critical care settings.
