Patient monitoring apparatus comprising an oesophageal probe including an oesophageal balloon for provoking the oesophagus of a patient to cause contractions therein, means for applying a fluid under to the oesophageal balloon, a sensor for detecting signals indicative of oesophageal contractions in the oesophagus of the patient, means for deriving from the said signals an output indicative of the degree of anaesthesia of the patient, and means for protecting the oesophagus of the patient from leakage of the fluid from the probe.
