The element can be used to manually set the breathing gas consumption for the dive (if no dive computer was used, or a dive computer without breathing gas integration). The value is to be given as a real number in the SI unit Pascal. It is up to the application program to provide the user with a possibility to enter the value in another unit (for example in bar) and to convert it then into Pascal.
(see also <dive>)
<!-- breathing gas consumption 140 bar -->
