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.

Ventilating patients with elevated oxygen tensions alters normal respiratory physiology and may damage lung tissue, depending on coexisting host and iatrogenic factors. Pulmonary oxygen toxicity begins at a cellular level when the generation of reduced oxygen intermediates exceeds local defenses. The mainstay of therapy is prevention.

Oxygen therapy and oxygen toxicity
Annals of Emergency Medicine, 1983When oxygen therapy is warranted, the minimum effective dose generally should be given. Hypoxemic patients who have normal baseline ABG may be treated initially with an intermediate to high FiO2 in the range of 35% to 100%, depending on the severity of the respiratory distress. The majority of patients with exacerbations of COPD who are not in extremis

Correct administration of oxygen to acutely breathless and hypoxic patients is vital. It must be tailored to achieve target saturations, rather than relying on a fixed percentage, because patients have different needs and respond differently to oxygen.

This article aims to give a general overview of oxygen therapy, both in the short and long term. Various methods of oxygen delivery and storage are discussed, along with the nurse's role in caring for a patient receiving oxygen therapy.

Interest in developing a method for predicting arterial oxygen tension following changes in inspired oxygen concentration (FIO2) has existed since the advent of oxygen therapy. Hess [1] has published a predictive formula to accomplish this, and Abizanda and Lopez [2,3] have presented the same method in a different form.

Cyanosis was used for a century after dentists began pulling teeth under 100% N(2)O in 1844 because brief (2Â min) severe hypoxia is harmless. Deaths came with curare and potent anesthetic respiratory arrest. Leland Clark's invention of a polarographic blood oxygen tension electrode (1954) was introduced for transcutaneous PO2 monitoring to adjust PEEP ...

It gets more and more frequent to use oxygen consumption (VO2) to evaluate exercise capacity and response to treatment in heart failure patients. The amount of VO2 is due to ventilation, oxygen transport and muscle activity. No one of these single steps can define by itself VO2, but all these physiological functions are integrated each other.
