Oxygen and Everest [PDF]

open access: possibleNature, 1932
MR. ODELL'S remarks,1 regarding Dr. Argyll Campbell's experiments, which were designed to test the power of acclimatisation of animals to low oxygen pressure, are not quite accurate. These experiments were undertaken to supply information that was wanting, and to endeavour to explain the adverse symptoms recorded in the official reports of the Everest ...

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.

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: (

Skin Permeability to Oxygen and Hyperbaric Oxygen

Archives of Surgery, 1970
It 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).

The motion of oxygen ions in oxygen

Journal of Physics B: Atomic and Molecular Physics, 1968
The drift velocities of positive and negative ions produced in a glow discharge in oxygen were measured within the range 5 < E/p 0 < 100 v cm-1 torr-1 (E is the electric field and p 0 the gas pressure reduced to 0 °c) for values of p 0 in the range 7·71 to 0·83 torr. The results

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.

Oxygen Content and Oxygen Flux

1988
Oxygen content and oxygen flux are two important concepts in understanding the meaning of any arterial PaO2.
