Isobaric counterdiffusion
Isobaric Counterdiffusion (Pronunciation: I-so-bar-ic Coun-ter-dif-fu-sion) is a term used in underwater diving and physiology to describe a phenomenon where different gases diffuse in opposite directions during the same time period.
Etymology
The term is derived from the Greek words 'isos' meaning equal, 'baros' meaning weight, 'counter' meaning against, and 'diffusion' referring to the process of spreading out.
Definition
Isobaric counterdiffusion occurs when a diver ascends or descends in a gas mixture different from the one in his or her breathing apparatus. This can lead to the formation of gas bubbles in the body, a condition known as decompression sickness or 'the bends'.
Related Terms

- Henry's Law: A principle in chemistry that states that the amount of dissolved gas is proportional to its partial pressure in the gas phase.
- Dalton's Law: A law of physics stating that the total pressure exerted by a gaseous mixture is equal to the sum of the partial pressures of each individual gas in the mixture.
