Abstract
Provided is a diver's information processing device for notifying a diver of a change in a pressure decrease ratio, at which pressure decreases during surfacing, for the purpose of minimizing the risk of a diver's decompression sickness and excess pulmonary expansion. In particular, when diving is performed at a high altitude, notification is made so that a pressure decrease ratio will be held lower than a pressure decrease ratio permitted at a low altitude. A diver's information processing device includes means that uses a pressure meter and a timer to calculate a pressure decrease ratio. Moreover, the diver's information processing device includes means that uses an acoustic notifier a vibration generator and a display panel to continuously notify a pressure decrease ratio, at which pressure applied to a diver decreases during surfacing, for the purpose of minimizing the dangers of diver's surfacing.
