Acid-Base Balance


Updated October 30, 2008

Definition: Acid-base balance refers to a mechanism developed by the body to keep bodily fluids as close to a neutral pH as possible. In doing so, bodily fluids are kept from becoming too acidic (having too much acid) or to basic (having too much alkaline). A proper acid-base balance allows the body to function in a state of equilibrium, or stability.

The acid-base balance system in a person with COPD is sometimes affected because of ineffective breathing patterns and the build-up of carbon dioxide. This can sometimes lead to respiratory failure, one of the complications of COPD.
