Haemoglobin, oxygen carriers and perioperative organ perfusion.
Under normal conditions, only 20-30% of the delivered oxygen is metabolised. In normovolaemic anaemia, the organism reacts with increases in cardiac output and oxygen extraction. Once these mechanisms are exceeded, allogeneic blood transfusions may be administered. However, such transfusions are associated with serious adverse effects and alternatives such as artificial oxygen carriers are bein...
متن کاملCerebral fractional oxygen extraction is inversely correlated with oxygen delivery in the sick, newborn, preterm infant.
Cerebral blood flow (CBF) is known to be low in newborn infants, but this has not been shown to be damaging. The purpose of this study was to investigate the relationships between cerebral haemoglobin flow, blood flow, oxygen delivery, oxygen consumption, venous saturation, and fractional oxygen extraction (OEF) in newborn, preterm infants. Measurements were made by near-infrared spectroscopy i...
متن کاملOxygen in neonatal anesthesia: friend or foe?
PURPOSE OF REVIEW Clinical practices in oxygen administration are in need of change based on the increasing understanding of oxygen toxicity. Hypoxemia is due to many pathophysiological causes; avoiding hypoxemia is an important objective during neonatal anesthesia. Nevertheless, the only known cause for hyperoxemia is the excess and unnecessary administration of oxygen by healthcare providers....
متن کاملMammalian sperm metabolism: oxygen and sugar, friend and foe.
Mammalian spermatozoa expend energy, generated as intracellular ATP, largely on motility. If the sperm cell cannot swim by use of its flagellar motion, it cannot fertilize the egg. Studies of the means by which this energy is generated span a period of six decades. This review gives an overview of these studies, which demonstrate that both mitochondrial oxidative phosphorylation, for which oxyg...
