Oxygen transport— the oxygen delivery controversy

Intensive Care Medicine, 2004
Most 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 Toxicity

Clinics in Chest Medicine, 1988
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, 1983
When 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

Oxygen treatment

Nursing Older People, 2009
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.

Oxygen therapy

Nursing Standard, 1998
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.

Oxygen Therapeutics (OXYGEN)

1989
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.
