Flying After Diving (At Altitude)

[badfrog88]

Everything I've read, so far, makes reference to flying after diving at sea level. A lot of my diving is done at altitude, sometimes as high as 4000+ feet. I'm wondering if any change should be made to the flying after diving recommendations. I haven't contacted DAN yet, as I was curious about what members of the forum thought.

Flying after altitude diving covers the same common problems associated with reduced atmospheric pressures as flying after diving at sea level.

Altitude diving requires that you use special tables or allow for altitude via a conversion to use with regular tables. Many computers do it automatically and some need to be set manually. I'm sure you know this as you seem familiar with altitude dving.

Anyway, increased pressure gradients still exsist when ascending from high altitude dives when flying, as they would if ascending from sea level.

So if you follow the flying after diving guidlelines and altitude diving procedures you should be able to manage these risks effectively.

Same issues. Most aircraft pressurize the cabin to 8000 feet or so. Some a little less, some a little more. So, the flying after diving safety rule still applies.

You can follow your computer no fly time recommendation. You can use the standard recommendations of 12 hours (one day of diving) or 18~24 hours (multi-day diving).

I live at 9000ft! I violate this whole no fly thing every time I dive below where I live (most CO dives)!
