What is the name of the equipment used to slowly decompression divers to prevent the bends?

What is a decompression chamber for divers?

A decompression chamber, or deck decompression chamber, is a pressure vessel for human occupancy used in surface supplied diving to allow the divers to complete their decompression stops at the end of a dive on the surface rather than underwater.

How does a diver avoid decompression sickness or the bends?

By taking a day off midweek, you decrease your nitrogen loading and give your body an opportunity to recover. Increase surface intervals, and decrease no-decompression limits. Use EANx. Enriched air nitrox reduces nitrogen in your breathing gas, making it easier to stay well within no-decompression limits.

What is the most important rule in scuba diving?

If you remember one rule of scuba diving, make it this: Breathe continuously and never hold your breath. During open water certification, a scuba diver is taught that the most important rule in scuba diving is to breathe continuously and to avoid holding his breath underwater.

What is the most common injury in scuba diving?

The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.

Why is it called the bends in diving?

Decompression sickness (DCS), known as ‘the bends’ because of the associated joint pain, is a potentially deadly condition caused by bubbles of nitrogen gas forming in the blood and tissues. It’s most common among divers using scuba tanks, but can affect free-divers and people at high altitude.

Why do divers get bends?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. This doesn’t cause a problem when a diver is down in the water.

Why do divers use a hyperbaric chamber?

The purpose a decompression hyperbaric chamber is to allow surface-supplied gas divers to complete their decompression stops in a chamber rather than underwater. … This reduces the risks for divers diving in cold waters or in risky underwater conditions.

Why do divers need hyperbaric chamber?

In a hyperbaric chamber, the diver is put under pressure in an oxygen-rich environment. The increased pressure helps reduce the size of any nitrogen bubbles that have formed in the patient’s tissue, and the increased levels of oxygen help the patient’s body disperse the nitrogen.

How long do you have to stay in a decompression chamber?

Side effects and possible complications of HBOT

During HBOT, you lie on a table in an enclosed chamber and breathe oxygen while the pressure inside the chamber is slowly increased. The therapy may last as little as 3 minutes or as long as 2 hours before the pressure is returned to normal levels.

Can the bends be cured?

If DCS is suspected, it is treated by hyperbaric oxygen therapy in a recompression chamber. Diagnosis is confirmed by a positive response to the treatment. If treated early, there is a significantly higher chance of successful recovery.

Will the bends go away on its own?

In some cases, symptoms may remain mild or even go away by themselves. Often, however, they strengthen in severity until you must seek medical attention, and they may have longer-term repercussions.
