PURPOSE:To know the degree of danger of the present intra-body nitrogen partial pressure, facilitate the physical strength control at the time of diving, and further improve the diving safety by outputting and displaying the ratio between the intra-body nitrogen partial pressure and the safety allowable limit quantity. CONSTITUTION:The safety allowable limit quantity at the time of floating of the partial pressure of the intra-organization inactive gas (nitrogen gas or the like) at each human body organization portion at the time of diving is set and stored in advance. The depth at the time of diving is detected, and the retention time at each depth is counted. The present intra-organization nitrogen gas partial pressure is calculated based on this detection result and counting, the ratio against the safety allowable limit quantity of this partial pressure is calculated, and this ratio is displayed and outputted in % on a display section 3. A diver can know the degree of danger of the present intra- body nitrogen partial pressure from this display and can easily perform the physical strength control at the time of diving. |
