- 40 - ABSTRACT OF THE DISCLOSURE An elongate probe for measuring oesophogeal contrac- tions and useful in a patient monitoring apparatus which generates an output indicative of the depth of the anaes- thesia of a patient, is described. In one embodiment, the probe has a distal end adapted to pass downwardly through the oesophagus of the patient and a proximal end adapted to lie externally of the mouth of the patient. The probe includes stimulating means adapted in use to lie within the oesophagus of a patient and operable by means of external to the patient for stimulating the oesophagus, to cause contractions therein. Pressure sensing means adapted in use to lie within the oesophagus of the patient enables the measurement of pressure within the oesophagus, thereby to sense contractions of the oesophagus .
