How long does it take for a diver to decompress?

It can take up to 24 hours for the body to return to its normal atmospheric levels of inert gas saturation after a dive. When time is spent on the surface between dives this is known as the “surface interval” and is considered when calculating decompression requirements for the subsequent dive.

How long does it take to decompress after saturation diving?

Saturation Operations Today, most sat diving is conducted between 65 feet and 1,000 feet. Decompression from these depths takes approximately one day per 100 feet of seawater plus a day. A dive to 650 feet would take approximately eight days of decompression.

Why does a diver get decompression sickness if they rise too quickly from a deep sea dive?

If a diver ascends too quickly, the nitrogen gas in his body will expand at such a rate that he is unable to eliminate it efficiently, and the nitrogen will form small bubbles in his tissues. This is known as decompression sickness, and can be very painful, lead to tissue death, and even be life threatening.

Why are bubbles bad for divers?

And if a diver rises to the surface (decompresses) at the right rate, the nitrogen can slowly and safely leave the body through the lungs. But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage.

What does skin bends look like?

Its primary symptom is a swelling of the skin, most often on the chest or arms. Swollen areas will have a pitted appearance, like the skin of an orange, and may be painful. If a swollen area is pressed lightly with the tip of a finger, the resulting indentation will remain for a few moments.

How deep can Technical Divers go?

130 feet
While the recommended maximum depth for conventional scuba diving is 130 feet, technical divers may work in the range of 170 feet to 350 feet, sometimes even deeper.
