The RADiUS protocol is a great list of applications that allows the care provider to identify the cause of dyspnea.


Evaluate for pericardial effusion/tamponade, pulmonary embolus (PE) (RV strain), congestive heart failure (CHF), acute MI.


Evaluate the volume status and fluid tolerance, as well as correlating the echo findings to pathology (enlarged IVC can occur with tamponade, large PE, and severe CHF).


Evaluate for pleural effusion, pneumothorax, pulmonary edema, pneumonia.
