This question relates to a vision with trimix software
On a 50m dive you have a problem ,it is serious enough to bailout (or in a moment of panic you think it is !)you abort the dive & start your ascent .At some point on the way up you decide to go back on the loop as you worked out it wasn't that serious .
Now the big question is how ? #
obviously you switched the onboard computer to oc so that dissabled the O2 injector so if you have ascended to your 10m stop the ppo will have dropped a lot ,as soon as you switch the computer back to cc it is going to dump O2 into the loop but with a time lag for it to get to the dsv is there still enough O2 to breath longenough to get the gas circulating ?
hope it makes sense
