Oxygen metabolism and oxygenation of the newborn [PDF]
Seminars in Fetal and Neonatal Medicine, 2020 The premature infant is to some extent protected from hypoxia, however defense against hyperoxia is poorly developed. The optimal assessment of oxygenation is to measure oxygen delivery and extraction. At the bedside PaO2 and SpO2 are approximations of oxygenation at the tissue level.

Eidos. A Journal for Philosophy of Culture, 2023 The article proposes a new, interspecies interpretation of Joanna Rajkowska’s Oxygenator. Read as what Anna Tsing calls latent commons and problematized through Chantal Mouffe’s concept of agonistic spaces, the canonical piece of public art is shown to ...

The ‘oxygen’ in oxygen minimum zones
Environmental Microbiology, 2022 AbstractAerobic processes require oxygen, and anaerobic processes are typically hindered by it. In many places in the global ocean, oxygen is completely removed at mid‐water depths forming anoxic oxygen minimum zones (A‐OMZs). Within the oxygen gradients linking oxygenated waters with A‐OMZs, there is a transition from aerobic to anaerobic microbial ...

Long-term ECMO, efficiency and performance of EUROSETS adult A.L.ONE ECMO oxygenator
Journal of Cardiothoracic Surgery, 2023 Background The management of the oxygenator can be prolonged in the long-term procedures especially during extracorporeal membrane oxygenation (ECMO) for bridge to transplant or bridge to recovery.

Post-Mortem Extracorporeal Membrane Oxygenation Perfusion Rat Model: A Feasibility Study
Animals, 2023 The development of biomedical soft- or hardware frequently includes testing in animals. However, large efforts have been made to reduce the number of animal experiments, according to the 3Rs principle.

May oxygen depletion explain the FLASH effect? A chemical track structure analysis [PDF]
, 2021 Background and purpose: Recent observations in animal models show that ultra-high dose rate ("FLASH") radiation treatment significantly reduces normal tissue toxicity maintaining an equivalent tumor control. The dependence of this "FLASH" effect on target oxygenation has led to the assumption that oxygen "depletion" could be its major driving force ...

The oxygen trail: tissue oxygenation [PDF]
British Medical Bulletin, 1999 Aerobic cellular respiration depends on the efficient supply of oxygen and substrate to the mitochondria. There is an oxygen cascade from the environment to the subcellular environment. Efficient oxygen delivery depends on the coordinated interaction between the respiratory and circulatory systems.
