Oxygen delivery, oxygen consumption and decreased kidney function after cardiopulmonary bypass.

open access: yesPLoS ONE, 2019
IntroductionLow oxygen delivery during cardiopulmonary bypass is related to a range of adverse outcomes. Previous research specified certain critical oxygen delivery levels associated with acute kidney injury.

Respiration Rates of Individual Bovine In Vivo-Produced Embryos Measured with a Novel, Scanning Electrochemical Microscopy

open access: yesJournal of Animal Reproduction and Biotechnology, 2014
Oxygen consumption is a useful parameter for evaluating mammalian embryo quality, since individual bovine embryos was noninvasively quantified by scanning electrochemical microscopy (SECM).

Chemical Power for Swarms of Microscopic Robots in Blood Vessels [PDF]

open access: yesarXiv, 2023
Microscopic robots in the bloodstream could obtain power from fuel cells using glucose and oxygen. Previous studies of small numbers of such robots operating near each other showed how robots compete with their neighbors for oxygen. However, proposed applications involve billions of such robots operating throughout the body.

Fetal oxygen delivery and consumption and blood gases in relation to gestational age [PDF]

open access: yesarXiv, 2021
Fetal oxygen delivery and consumption and blood gases in relation to gestational age. Oxygen crosses the placenta by diffusion and placental permeability to O$_2$ is high. Thus, the fetus receives adequate amounts, but vascular Po$_2$ is much lower than after birth. Studies of sustained fetal hypoxemia and acute 40-45% hemorrhage show that hypoxemia is

Measuring Oxygen Consumption Rate in Caenorhabditis elegans

open access: yesBio-Protocol, 2016
The rate of oxygen consumption is a vital marker indicating cellular function during lifetime under normal or metabolically challenged conditions. It is used broadly to study mitochondrial function (Artal-Sanz and Tavernarakis, 2009; Palikaras et al ...

Noninvasive in vivo photoacoustic measurement of internal jugular venous oxygenation in humans [PDF]

open access: yesarXiv, 2023
In many clinical conditions, such as head trauma, stroke, and low cardiac output states, the brain is at risk for hypoxic-ischemic injury. The metabolic rate and oxygen consumption of the brain are reflected in internal jugular venous oxygen saturation (sijvO2). The current gold standard for monitoring brain oxygenation is invasive; it requires jugular

Metabolically exaggerated cardiac reactions to acute psychological stress: The effects of resting blood pressure status and possible underlying mechanisms [PDF]

open access: yes, 2010
The study aimed to: confirm that acute stress elicits metabolically exaggerated increases in cardiac activity; test whether individuals with elevated resting blood pressure show more exaggerated cardiac reactions to stress than those who are clearly ...
