Hyperoxia in Extreme Hemodilution [PDF]

European Surgical Research, 2002
Intraoperative surgical blood loss is initially replaced by infusion of red cell-free, cristalloidal or colloidal solutions. When normovolemia is maintained the ensuing dilutional anemia is compensated by an increase of cardiac output and of arterial oxygen extraction.

Hyperoxia for performance and training

Journal of Sports Sciences, 2017
Recent technological developments have made it possible to use hyperoxia as an enhancement aid during training. Athletes wearing a mask can breathe a higher fraction of oxygen from a stationary or portable apparatus while exercising. A large body of evidence indicates that the oxygen transport capacity, lactate metabolism, power output and work ...

Effects of hyperoxia in pediatric perfusion patients: a scoping review

The Journal of ExtraCorporeal Technology
Hyperoxia in pediatric cardiopulmonary bypass patients is associated with adverse effects, including reoxygenation injury, increased mortality, heightened inflammatory response, and cerebral injury.

Cerebral Perfusion Response to Hyperoxia [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2007
Graded levels of supplemental inspired oxygen were investigated for their viability as a noninvasive method of obtaining intravascular magnetic resonance image contrast. Administered hyperoxia has been shown to be effective as a blood oxygenation level-dependent contrast agent for magnetic resonance imaging (MRI); however, it is known that high levels

Hyperoxia-induced deterioration of diastolic function in anaesthetised patients with coronary artery disease – Randomised crossover trial [PDF]

BJA Open, 2023
Background: There are no current recommendations for oxygen titration in patients with stable coronary artery disease. This study investigates the effect of iatrogenic hyperoxia on cardiac function in patients with coronary artery disease undergoing ...

Hyperoxia in depression [PDF]

European Psychiatry, 2021
Introduction Several studies of normobaric hyperoxia in some neurological conditions have demonstrated clinical benefits. Oxygen enriched air may increase oxygen pressure in brain tissue and have biochemical effects such as on brain erythropoietin gene expression, even in patients without lung disease.

Dangers of hyperoxia [PDF]

Critical Care, 2021
AbstractOxygen (O2) toxicity remains a concern, particularly to the lung. This is mainly related to excessive production of reactive oxygen species (ROS).Supplemental O2, i.e. inspiratory O2concentrations (FIO2) > 0.21 may causehyperoxaemia(i.e. arterial (a) PO2 > 100 mmHg) and, subsequently,hyperoxia(increased tissue O2concentration), thereby ...

HS-GC–MS analysis of volatile organic compounds after hyperoxia-induced oxidative stress: a validation study

Intensive Care Medicine Experimental
Background Exhaled volatile organic compounds (VOCs), particularly hydrocarbons from oxidative stress-induced lipid peroxidation, are associated with hyperoxia exposure.

Neonatal hyperoxia promotes macrophage senescence and lung injury via a p38MAPK-dependent secretome. [PDF]

Am J Respir Cell Mol Biol
Rationale Bronchopulmonary dysplasia (BPD), a chronic lung disease in premature infants exposed to ventilatory support and hyperoxia, involves alveolar and vascular simplification and is linked to cellular senescence.

Hyperoxia and the Immature Brain [PDF]

Developmental Neuroscience, 2016
Despite major advances in obstetrics and neonatal intensive care, preterm infants frequently suffer from neurological impairments in later life. Preterm and also full-term neonates are generally susceptible to injury caused by reactive oxygen species due to the immaturity of endogenous radical scavenging systems.
