PCT No. PCT/AU96/00306 Sec. 371 Date Feb. 19, 1998 Sec. 102(e) Date Feb. 19, 1998 PCT Filed May 20, 1996 PCT Pub. No. WO96/36279 PCT Pub. Date Nov. 21, 1996A device and method for detecting and recording the snoring of a patient. The device comprises a piezoelectric sensor, placed below a sleeping patient on a mattress, which generates signals representative of the sub-audible vibrations of the patient's airway which are present during a snore. The signals generated by the sensor can be amplified by an amplifier and processed by a signal processing circuit. The sensor can also generate signals representative of the patient's breathing cycle and general movement of the patient. The signal processing circuit can be adapted to discriminate the signals generated by the sensor and then output these signals for analysis. The output can be used to determine the presence of snoring by the patient and the snoring pattern can also be used to detect episodes of obstructive sleep apnea.
