    If it's that big of a worry and you're right on the NDL edge, then just do a controlled ascent while exhaling (similar to a CESA) until you just have to take a breath. By the time you need to breath off of the pony, you might be at your safety stop depth and you won't have a problem. If you just have to hit the pony at depth prior to doing your ascent, well, that's life. And as previously stated, it's probably not that big of a deal anyway. You're going to be there so briefly that it just isn't going to put you in a bind that a few hours on the surface won't take care of.

    Is this an April fool's post or what? He has 30 cu-ft of air, way more than he needs to ascend, why the hell would he do something so stressful?

    If I were doing the ascent, i would probably come up 60 feet per minutes for 30-40 feet, then I'm at 90 or 100 feet in only 30 seconds then do a slow ascent from 100 to 50 feet in a couple of minutes, chill at 50 feet for 2 minutes and then slowly ascend to 20 feet for a couple more. NOT A BIG DEAL.

    After surfacing, I would check Neptune's C-cards. He shouldn't have been spearing you unless he has the required specialties.

    thank you peter you are rite a normal ascent, dont over think the hypo your out of gas at 130 ascend and switch to pony in a sport con fig your pony should be breathable at you max depth on this hypo air is ok the big issue is what got you to that point fix that first . and a mod of 1.6 your not ( dead) just teasing the reeper whats the rittle me this just for fun whats the ppo2 21% at 210 for 35 min bottom time(this is a dive we did in chukk and were not dead or bent) lol
    enjoy this and have fun kicking me around and as your mom
    says dont do as I do
    do as I say and dive safe a 1.4 is a good plan.

    why not do the 130-70 at 60 per minute isnt that the current guidance with 30 per min above 60 ft. perobably stay at 70 for 3-5 with the saved air and go to safety stop and surface for the beer and cigar. or am i missing something

    Just by chance... have you ever seen a seizure? now if you have .. were they underwater? and if they were... did they survive?

    I have seen seizures and don't plan my dive over 1.4 so that if in an emergency I go to 1.6 for a short while i will reduce my chances of a seizure. I know a commercial diver that has been on 100 percent to sixty feet......

    but he was in a chamber after a dive on the way up from like 300ft probably. flip of the switch his FiO2 could be changed in seconds. by the way this amazes me after hearing this story.. have you heard anything like this?
