flying and altitude restrictions before and after a dive?

[kat.hayes]

What are the flying and altitude restrictions that need to be followed before and after a dive?

Thanks.

If you fly to a destination for diving you can dive on arrival. Restrictions for air travel exist after diving and they can be 12 to 24 hours based on the amount of diving you do. If you use a computer for diving alot now will inidicate no fly time after dives.

Flying immediately before diving will actually reduce the risk of DCS slightly. You will be offgassing during flight, which is why flying after diving may trigger DCS, hence tissues will not be completely saturated when you start the dive.

As noted, no restrictions before diving. Diving & flying is all about pressure, once you are "loaded" with nitrogen sudden pressure increases or drops will have an impact on your current decompression (off gassing) obligations. I have seen divers get bent while flying. Take flying after diving very serious!!!!!

The only thing about diving after flying is the possibility of being tired and dehydrated, both of which should be avoided when diving.

As for flying after diving, see http://www.diversalertnetwork.org/ne...spx?newsid=258

Different agencies have varying guidelines, but all recommend not flying 12-24 hours after diving.

For PADI, the recommendations are:

Single Dive on Single Day: 12 hours before flying.

Repetitive dives (2+) or consecutive multi-day diving: 18 hours before flying.

If you have a dive computer, then that will give you a no-fly time based on the actual diving you did (according to it's algorythm).

Flying immediately before diving will actually reduce the risk of DCS slightly. You will be offgassing during flight, which is why flying after diving may trigger DCS, hence tissues will not be completely saturated when you start the dive.

That was a deliberate joke right?

Let' see.....deydration.....fatigue.....etc.

I would think that this should be, increased risk, due to dehydration and fatigue. Correct me if I am wrong.

[DevonDiver]

The pressure difference in a pressurised cabin will be so minute, that any change in the gas saturation of tissues would be negligible. In contast, the forced immobility of the lower torso would have a lingering effect on lower limb circulation. Likewise, the 'dry' air inside the plane would significantly increase dehydration. These negative factors would more than outweigh any hypothetical benefit of reduced tissue saturation from the flight.

Practically speaking, this is a bit of an urban myth. It's only true if you take a long flight (many hours) and get in the water within a few minutes of landing (not forgetting that it can already take 15-30 minutes for a long haul flight to descend from altitude). Look at your basic dive tables and think about how fast you on gas and how long it takes to off gas. In theory, you might have a small benefit in the really slow tissues, but any tissue which is even moderately fast will be close to saturation by the time you get in the water and the effects will dominate.
