Flying after diving?

[Andy Phillips]

Mate,

I know I am stupid, but I did a 50M dive at 8.30amnd caught a plane at 4.30PM, mind you I was going to aberdeen, and if I was going to be bent that would be the place to be.

Just use common sense, if your talking about a 65M dive with two hours of deco your nuts, 50M with 45 mins did not particually worry me.

If you fly with a decent gas load you will get hit DAN data shows you need 28hrs to be safe.
I do wonder if those that fly under the guidelines already have bubbles in their brains

Yes!

Have a look at the altitude transfer table at the back of your 88's, then look how much more deco is recommended for a level 2 dive over a level 1. Then remember that all flights are considered to be level 4. Then book a later flight.

It is serious but perhaps not as long as the blanket 24 hours.

Without doing a whole lot of maths: Look at tables with stops in. Look at how the stop lengths are small for 12 and 9, go up at 6 and then rack out into the distance at 3.
A pressurised aircraft is usually set to about 7000ft which is the equivalent of going 2.7m shallower. If that's where you want to go how long does your 0m stop need to be? It is going to be hours and you're only breathing 21%.

You really don't want to take a big gas loading to -2.7m and get dehydrated too. Any 'sub clinical' bend, and I suspect we see a lot of them just as extra weariness, will have plenty of time to make problems so if you are doing this then do lots of deep stops (2mins+ every 10m) and then hang on the highest mix you can do at 6 so the microbubbles are still going round until your buddies physically drag you out.

I wouldn't push it and I'm an idiot. If I'm going to get bent it will not be trapped in a metal tube with several hours between me and Gatwick.

Thanks all. Forewarned is forearmed...

We did one week of intense diving daily. Dives ranged from 40 min at 40 meters all the way to 20 minutes at 90 meters. Andrew Georgitsis did the last dive on the Russian Freighter (60 meters for half an hour or so) at around 4 o clock in the afternoon and was in the plane at 9 pm. Clean deco allows for that.

Hi Mozi,

for the Muppets amongst us, care to explain what you mean by 'clean deco'?

Cheers,

Hi Mr. T,

Thank for the welcoming

Clean deco is just that, clean deco. Throughout the years, the WKPP and GUE have been refining decompression strategies to a point where you come up with minimal inert gas loading essentially reaching a "bubble free" status very quickly. That time depends on your vascularity. So if you do that deco, you can go up mountains or ride in an airplane.

Hi there,

Sorry for the thread hijack, but what do you mean by vascularity?

Cheers,

PS - My personal viewpoint is that the biggest risk of flying after diving is that treatment isn't easily accessible if you're on the plane. What could be a minor hit if there's a chamber an hour away could be much worse if you're in the air.
