The ‘oxygen’ in oxygen minimum zones

open access: yesEnvironmental Microbiology, 2022
Abstract Aerobic 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).

Oxygen therapy in respiratory disorders [PDF]

open access: yes, 2012
PhDOxygen therapy remains a cornerstone of medical practice and is generally regarded as being safe. However, there is a lack of clinical evidence to support the routine use of oxygen therapy, and in certain conditions, injudicious oxygen may cause harm.

Oxygen metabolism and oxygenation of the newborn [PDF]

open access: yesSeminars 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.

Oxygen therapy: professional compliance with national guidelines [PDF]

open access: yes, 2014
One of the major causes of critical illness in the UK is the deterioration of respiratory function (British Thoracic Society (BTS), 2008). The administration of supplemental oxygen therapy, although often lifesaving, can also have serious consequences if

Understanding Hydrogen: Lessons to Be Learned from Physical Interactions between the Inert Gases and the Globin Superfamily

open access: yesOxygen, 2022
Hydrogen gas (molecular hydrogen, H2) has significant effects in a range of organisms, from plants to humans. Many inert gases have been reported to have similar effects, and such responses may be most pronounced when cells are stressed.

Complete Recovery of an Iatrogenic Venous Gaseous Embolism (VGE) Clinical Presentation Thanks to a Timely Hyperbaric Oxygen Therapy (HBOT) Treatment

open access: yesOxygen, 2022
Gas embolism is a potentially fatal occurrence in which bubbles are introduced into the arterial/venous circulation. A multifocal ischemia could be the life-threatening scenario of that and occurring after diving-related activities, or pulmonary ...

RONS and Oxidative Stress: An Overview of Basic Concepts

open access: yesOxygen, 2022
Oxidative stress (OS) has greatly interested the research community in understanding damaging processes occurring in cells. OS is triggered by an imbalance between reactive oxygen species (ROS) production and their elimination by the antioxidant system ...

The oxygen trail: tissue oxygenation [PDF]

open access: yesBritish 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.
