I’m always scared to scuba dive because I heard if you come up to fast it can make bubbles in your blood and you die, is that true?

Yes and no. What you’re describing is what’s called “The Bends” where the nitrogren in your blood stream can turn to bubbles if you don’t ascend correctly. A big part of the PADI training describes the procedures you should follow that would prevent this happening, e.g. using a dive computer or dive tables to plan your dive.

If you’re doing simple shallow recreational dives like this, and following the (very conservative) rules then the chances of getting the bends are very small indeed.

In fact, the biggest risk of the bends if for very advanced divers that dive very deep (like 100m/300ft), and are required to do decompression stops during their ascent to reduce the nitrogen.

This is beyond the PADI Open Water certification whict most divers have.

I got my Junior Advanced Open Water Diver certification right before I turned 14…
I first got certified a few months before I turned 12.

When you do Advanced, I recommend doing Enriched Air and dry suit with it. You get a reduced cost with the nitrox.

how long does the gas tank last?

By: neilp2

neilp2 — Thu, 25 Feb 2010 11:53:05 +0000

that depends on a number of factors:
1) how big your tank is
2) how quickly you breathe (which can be quite quick for beginners)
3) how deep you go

A typical recreational dive is of the order of 30 to 45 minutes.

Does the tank just contain pure oxygen or…?

air cylinder*

By: neilp2

neilp2 — Thu, 25 Feb 2010 08:28:02 +0000

Generally it’s just normal air, though it’s filtered and the moisture is reduced before it’s compressed. so 80% Nitrogen, 19% Oxygen and 1% other.

Advanced divers can also specialize in enriched air (Nitrox) which has a higher oxygen content and allows you to dive for a little longer.
