Subclavian vein collapsibility as a predictor of fluid responsiveness in spontaneously breathing hypotensive patients.

The results of the study show that right subclavian vein respiratory variation has the ability to predict fluid responsiveness in a spontaneously breathing patient in circulatory shock and correlates with Inferior Vena Cava collapsibility index. Subclavian vein can be an alternative to Inferior Vena Cava in predicting fluid responsiveness in spontaneously breathing patients.
