Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid which is capable of CO 2 gas exchange (such as a perfluorocarbon). [ 1 ] The liquid involved requires certain physical properties, such as respiratory gas solubility, density, viscosity, vapor pressure and lipid solubility, which ...
Sea slugs respire through a gill (or ctenidium). Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.

Snorkel breathing is inherently negative pressure breathing, as the lungs of the swimmer are at least partly below the surface of the water. [ 16 ] There appears to be a connection between negative pressure breathing and a higher risk of pulmonary oedema while diving, as it increases the pressure difference between alveolar blood and gas. [ 95 ]
As a person breathes, the body consumes oxygen and produces carbon dioxide. Base metabolism requires about 0.25 L/min of oxygen from a breathing rate of about 6 L/min, and a fit person working hard may ventilate at a rate of 95 L/min but will only metabolise about 4 L/min of oxygen [10] The oxygen metabolised is generally about 4% to 5% of the inspired volume at normal atmospheric pressure, or ...
