AMPK breathing and oxygen supply

The emerging role of AMPK in the regulation of breathing and oxygen supply

Regulation of breathing is critical to our capacity to accommodate deficits in oxygen availability and demand during, for example, sleep and ascent to altitude. It is generally accepted that a fall in arterial oxygen increases afferent discharge from the carotid bodies to the brainstem and thus delivers increased ventilatory drive, which restores oxygen supply and protects against hypoventilati...

The oxygen cost of breathing.

Oxygen concentrators: a primary oxygen supply source.

PURPOSE Efforts to harmonize the standards of the CSA and the ISO, as they relate to compressed medical gas supply and piping, prompted us to review ten years experience with oxygen concentrators (OCs) in Canada used as a primary hospital oxygen supply. The goals of this study were; 1) To document the number of Canadian OC Hospital sites, 2) to define what impact these units have had on medical...

Effects of Oxygen Breathing on the Heart

Oxygen breathing has been used extensively to treat a wide variety of clinical disorders. An understanding of its effects on the normal circulation, at rest and under conditions of increased cardiac output, is fundamental to the understanding of the efficacy of oxygen therapy in clinical situations. Furthermore, interpretation of physiologic data concerning the effects of hyperoxia on the regio...

Oxygen breathing challenge- the simplest theranostic

Multispectral optoacoustic tomography provides insights into tumor vascular oxygenation with high temporal and spatial resolution non-invasively. New work indicates that a simple oxygen breathing challenge can reveal differences in tumor, potentially as a prognostic biomarker.
