Diving medicine

condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level

use of high concentrations of oxygen as medical treatment

pressure vessel for human occupation

condition resulting from the harmful effects of breathing molecular oxygen at increased partial pressures

medical treatments at raised ambient pressure

Hypercapnia (from the Greek hyper, "above" or "too much" and kapnos, "smoke"), also known as hypercarbia and CO2 retention, is a condition of abnormally elevated carbon dioxide (CO2) levels in the blood. Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs.

physiological response to immersion of air-breathing vertebrates

diagnosis, treatment and prevention of conditions caused by humans entering the undersea environment

Hyperoxia is the state of being exposed to high levels of oxygen; it may refer to organisms, cells and tissues that are experiencing excessive oxygenation, or to an abnormally high oxygen concentration in an environment (e.g. a body of water).
