PURPOSE:To prevent decompression illness by appropriately detecting the change in atmospheric pressure even after diving. CONSTITUTION:When diving is finished, atmospheric pressure is detected, and altitude is computed. Then, the nitrogen partial pressure in a body, the risk degree X of boarding in an aircraft, the complete discharging time Ta of nitrogen remaining in a body and the prohibiting time Tf of boarding in an aircraft are computed. When the computations are completed, a display driving circuit 2 is driven. The computed altitude, the risk degree X of boarding in the aircraft, nitrogen remaining in the body (nitrogen partial pressure in a body), the complete discharging time Ta of nitrogen remaining in the body, the prohibiting time Tf of boarding in the aircraft and the total time are displayed on a display part 3 and outputted. When the display and output are completed, the detection of atmospheric pressure and the processing after the diving are performed at every three seconds until the complete discharging time Ta of the nitrogen remaining in the body becomes '0'. |
