depending on the oxygen consumption of the diver.
Warning!
You must carefully consider the relation-ship
between nitrox mixture and flow rate. NEVER dive
with a mixture that will provide more than 1.6 ATA
partial pressure of oxygen at any time. For any dives
where heavy exertion is anticipated or where more than
a few minutes will be spent at the greatest depth, make
sure the oxygen partial pressure does not exceed 1.4
ATA in accordance with generally recognized safe
diving practices of all nitrox training agencies. Failure to
follow these recommendations could lead to an oxygen
toxicity problem which could lead to serious injury or
death.
When diving with the DrägerRay the guidelines for the
usage of mixed gases which are recommended by trai-
ning organizations world-wide must be con-sidered. No
liability will be assumed by Dräger Sicherheitstechnik
GmbH for possible adverse effects caused by oxygen
toxicity or other mishaps.
