BREATHING OXYGEN

The oxygen cost of breathing.

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.

Serum erythropoietin levels in healthy humans after a short period of normobaric and hyperbaric oxygen breathing: the “normobaric oxygen paradox”. Running head: EPO increase after oxygen breathing

Oxygen or carbogen breathing before simulated submarine escape.

Raised internal pressure in a distressed submarine increases the risk of bubble formation and decompression illness after submarine escape. The hypothesis that short periods of oxygen breathing before submarine escape would reduce decompression stress was tested, using Doppler-detectable venous gas emboli as a measure. Twelve goats breathed oxygen for 15 min at 0.1 MPa before exposure to a simu...
