'''Decompression Theory''' is a concept in [[underwater diving]] and [[hyperbaric medicine]] that involves the study of the processes and effects of reducing ambient pressure on a diver who has been breathing at high pressure. It includes the procedures for decompression and the models used to predict the risk of [[decompression sickness]].

== History ==

The history of decompression theory dates back to the 19th century when [[Paul Bert]] and [[John Scott Haldane]] conducted studies on the effects of pressure on the human body. Their work laid the foundation for modern decompression theory.

== Basic Principles ==

Decompression theory is based on the understanding that gases dissolve in liquids under pressure. When the pressure is reduced, the gases come out of solution, forming bubbles. If the pressure reduction is too rapid, these bubbles can cause tissue damage and lead to decompression sickness.

== Decompression Models ==

There are several decompression models used in the study and application of decompression theory. These include the Haldane model, the Bühlmann model, and the Varying Permeability Model (VPM).

=== Haldane Model ===

The [[Haldane Model]] was developed by John Scott Haldane in the early 20th century. It is based on the concept of tissue compartments with varying half-times for gas absorption and elimination.

=== Bühlmann Model ===

The [[Bühlmann Model]] was developed by Albert A. Bühlmann and is based on the concept of multiple tissue compartments with different half-times for gas absorption and elimination.

=== Varying Permeability Model (VPM) ===

The [[Varying Permeability Model]] (VPM) was developed by David Yount and is based on the concept of bubble formation in tissues during decompression.

== Decompression Procedures ==

Decompression procedures are the practical application of decompression theory. They involve the controlled reduction of ambient pressure to allow the safe elimination of dissolved gases from the body.
