Decompression equipment

Decompression equipment is a category of diving equipment used by underwater divers to safely ascend from depth. The equipment aids in the prevention of decompression sickness, a potentially serious condition caused by rapid changes in pressure.

Overview

Decompression equipment is designed to control the rate of ascent in scuba diving and technical diving, allowing the body to eliminate absorbed inert gases, such as nitrogen, slowly to prevent bubble formation in the tissues. This process is known as decompression.

Types of Decompression Equipment

Decompression Buoy

A decompression buoy, also known as a decompression sausage or SMB (surface marker buoy), is a buoyant device that allows a diver to mark their position underwater. It is often used during decompression stops to signal the diver's location to surface support personnel.

Decompression Trampoline

A decompression trampoline is a suspended net used by commercial divers during in-water decompression. It provides a stable platform for divers to hold onto during long decompression stops.

Decompression Chamber

A decompression chamber, also known as a recompression chamber, is a sealed environment used to gradually reduce the ambient pressure around a diver. It is typically used in surface decompression, where the diver ascends to the surface at a faster rate and completes their decompression in the chamber.

Safety Considerations

Proper use of decompression equipment is crucial for diver safety. Divers must be trained in the correct procedures for decompression and the use of the equipment. Failure to decompress properly can lead to serious health risks, including decompression sickness and arterial gas embolism.
