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

Oxygenation, oxygen delivery and anaesthesia in the horse

Equine Veterinary Journal, 2014
Summary Horses are the most difficult of the common companion animals to anaesthetise. Hypoxaemia or inadequate oxygen delivery to peripheral tissues during anaesthesia would seem a potential cause of increased mortality, but no direct link has been established.

Clinical Use of Oxygen Stores: Pre-oxygenation and Apneic Oxygenation

1992
During states of respiratory arrest the human oxygen stores may be used therapeutically, regardless of the origin, i.e. either prior to the routinely induced apnea for endotracheal intubation or as an emergency measure in any other case of apnea. The present considerations focus on the clinical use of the oxygen stores available, applying.

Perioperative oxygen therapy and oxygen utilization

Current Opinion in Critical Care, 2010
Tissue hypoxia is a key trigger for organ dysfunction. The maintenance of adequate tissue oxygenation is therefore of particular importance during major surgery. In this review, we discuss the physiological basis and the rationale underlying the recent concepts of perioperative oxygen therapy.Adequate tissue oxygenation is vital for optimal tissue ...

Monitoring oxygen transport and tissue oxygenation

Current Opinion in Anaesthesiology, 2004
To review recent publications in the field of oxygen delivery and tissue oxygenation. With few exceptions, we restricted our selection to clinical studies published in the English literature.No major breakthroughs have occurred in the past decade in the diagnosis or treatment of tissue hypoxia.

Dependence of Tissue Oxygen on Oxygen Delivery

Journal of Surgical Research, 1996
The viability of tissue flaps depends on adequate blood flow and oxygenation. To help ensure oxygen delivery, increased inspired oxygen is often provided. This study uses a porcine model to measure tissue oxygen (TPO2) in a muscle flap, in response to varying levels of inspired oxygen concentration (FiO2).

Halothane Mimics Oxygen in Oxygen Microelectrodes

Anesthesiology, 1979
The effects of halothane and enflurane on the polarographic measurement of oxygen with five platinum and three gold microelectrodes were examined. Oxygen microelectrodes were calibrated in saline solution equilibrated with either nitrogen (N2) or air, then either halothane, 1.0 per cent, or enflurane, 2.0 per cent, was added to the gas mixture.

The relationship between oxygen demand, oxygen uptake, and oxygen supply

Intensive Care Medicine, 1990
Results of the relationships between oxygen supply, demand, and uptake can be used to interpret cardiac output values, identify types of acute circulatory failure, guide attempts to improve cellular function, and thus prevent the development of multiple organ failure and death. Five steps in the interpretation of cardiac output values are recommended: (

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.

Oxygen Supply and Placental Oxygen Metabolism

1994
There have been numerous previous reports of investigations into the relationship between oxygen supply and oxygen metabolism in human tissues and organs and a variety of animal tissues and organs. Those studies have encompassed both in vivo and in vitro preparations and have included perfusions with whole blood and with artificial perfusion in the ...
