Abstract
An apparatus for monitoring patient functions, particularly depth of anesthesia includes an oesophageal probe having a balloon located in the patient's oesophagus to provoke contractions thereof; a gas cylinder or pump for applying air or saline solution to the balloon and a sensor for detecting signals indicative of oesophageal contraction, from which signals the depth of anesthesia may be estimated.
