Description

Caloric testing is the gold standard test of lateral semi-circular canal function. It consists of introducing warm and cool air or water into a patient's ears and measuring the eye movements it causes. Left ear responses are compared to right ear responses which can tell us if one system is weaker than the other.

This video shows the full caloric testing process, both warm and cool irrigations in each ear.
