Oxygen transport— the oxygen delivery controversy
Intensive Care Medicine, 2004Most cellular activities require energy in the form of oxygen, primarily obtained from the degradation of adenosine triphosphate (ATP) and other high-energy compounds. Oxygen must be present in sufficient amounts in the mitochondria to maintain effective concentrations of ATP in the electron transport system.

Oxygen (O(2)) is a vital element. Shortage of O(2) results in deranged metabolism and important changes in vascular tone with opposite effects on the systemic and pulmonary circulation. During hypoxemia, oxidative stress exposes the organism to a sort of accelerated senescence as well as to several acute untoward effects.

Like most bacteria, Escherichia coli has a flexible and branched respiratory chain that enables the prokaryote to live under a variety of environmental conditions, from highly aerobic to completely anaerobic. In general, the bacterial respiratory chain is composed of dehydrogenases, a quinone pool, and reductases ...

Skin Permeability to Oxygen and Hyperbaric Oxygen
Archives of Surgery, 1970It has been assumed that exposure to oxygen and hyperbaric oxygen (HPO) is beneficial to hypoxic skin in part because oxygen directly penetrates the tissues. Thus, it was felt necessary to determine the extent of tissue permeability to oxygen in terms of elevation of the tissue oxygen tension (TOT).
