As we’ve seen, as you descend on a dive, the increased pressure causes the volume of air in your lungs to decrease. But as this happens, the partial pressure of the air inside your lungs increases. This means that there is a greater concentration of oxygen and other gases in our lungs than there is in the blood.
How long does a dive computer last?

In the first 30 or so feet underwater, the lungs, full of air, buoy your body toward the surface, forcing you to paddle as you go down. You feel the pressure on your body double at 33 feet underwater. At this depth, the contracting air will shrink your lungs to half their normal size.

How deep can you dive without decompression?
The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.
