Hypoxie and Hyperoxia

Deutsche Zeitschrift für Sportmedizin, 2019
In contrast tothe various acute and chronic responses to hypoxia (i.e., lowering of the partial pressure of oxygen in the air, for example by various forms of altitude training), far less is known about the responses to acute, and especially to chronic exercise in hyperoxia (i.e. elevation of the fractional oxygen content of air). The acute exposure to

Heliox versus trimix in closed‐circuit rebreather diving: A comparative study of pulmonary and decompression stress in male divers

Physiological Reports, Volume 14, Issue 19, October 2026.
Abstract Closed‐circuit rebreather (CCR) and helium‐based breathing mixtures are widely used in technical diving. This study compared the effects of Heliox and Trimix on pulmonary function and decompression stress during CCR dives. Nineteen divers performed a standardized dive (50 ± 3 msw, 147 ± 10 min) using Heliox (16% O2/84% He; n = 9) or Trimix (16%

The Effect of Hyperoxia on Nitric Oxide Metabolism in the Skeletal Muscle of Male Type 2 Diabetic Rats

Endocrinology, Diabetes & Metabolism
Introduction Hypoxia is involved in the pathophysiology of type 2 diabetes (T2D), and oxygen therapy (hyperoxia) has been proposed for managing T2D. As a side effect, hyperoxia increases nitric oxide (NO) metabolism and decreases NO bioavailability. This

FAM134B deletion exacerbates apoptosis and epithelial-to-mesenchymal transition in rat lungs exposed to hyperoxia

iScience
Summary: Oxygen therapy is widely used in clinical practice; however, prolonged hyperoxia exposure may result in hyperoxic acute lung injury (HALI). In this study, we investigated the role of FAM134B in hyperoxia-induced apoptosis, cell proliferation ...

NF-kappaB involvement in hyperoxia-induced myocardial damage in newborn rat hearts.

, 2013
Premature newborns are frequently exposed to hyperoxia ventilation and some literature data indicate the possibility of hyperoxia-induced myocardial damage.

Mechanisms of hyperoxia-induced retinal endothelial cell death and senescence

, 2013
Purpose Hyperoxia is a dominant pathogenic factor in retinopathy of prematurity (ROP) resulting in arrest of normal vascular development and vaso-obliteration of pre-established retinal vessels.
