<p>Air pressure information at the destination of movement of the user or along the path of movement thereof is set. According to the amount of inert gas expected to be accumulated in the user's body at the destination or along the path based on the amount of inert gas estimated to be in the user's body and the air pressure information, it is judged whether or not the movement to the destination or along the path is safe. If not, the diver being the user is made to notice the danger and the possibility that the movement may cause dysbarism, thus preventing an accident attributed to decrease in air pressure.</p> |
