An apparatus for preventing a dyspnoea in sleep includes an air chamber(120,130), an air supplying unit(140), a pressure sensor(150), a semiconductor microphone(160) and a controller(170). The air chamber is located on a back of human make expansion and contraction of the apparatus possible. The air supplying unit supplies the air into the air chamber. The pressure sensor measures a change of heartbeat or respiration of a sleeper and outputs the change into an electrical signal. The semiconductor microphone measures vibration and outputs the vibration into an electrical signal. The controller changes a posture of the sleeper by supplying the air into the air chamber. |
