<p>A sleep monitoring apparatus comprising a removable support (31) adapted to be mounted on the body of a patient. An acoustical device (36) is provided which is adapted to be positioned on the face of the patient in the vicinity of the nose and/or mouth of the patient and has at least one acoustic duct (39, 41 , 42) receiving respiratory airflow from the patient. A sensor (46) which is exposed to the acoustic duct is provided for sensing turbulence and/or pressure changes in the respiratory airflow in the acoustic duct and providing an electrical output. Electrical circuitry (61) is carried by the support for receiving the electrical output and for processing the electrical output to provide a real-time signal from the support which is indicative of the breathing of the patient.</p> |
