Cytopathic dysoxia
WebIn 1997, Fink coined the term “cytopathic hypoxia” to describe such states. 162 In 1997, as the study of oxygen supply and utilization evolved, Robin proposed the general term “dysoxia” to describe abnormal tissue oxygen metabolism, and this is the term used in this chapter. 163 Now four classifications are recognized: hypoxemic dysoxia, anemic … WebFeb 1, 2002 · Impaired oxygen extraction as a result of impaired cellular respiration has been termed cytopathic hypoxia. 105 Several other mechanisms have also been implicated in the impaired oxygen...

WebA number of different biochemical mechanisms have been postulated to account for cytopathic hypoxia in sepsis, including reversible inhibition of cytochrome a,a3 by nitric oxide, and irreversible inhibition of one or more mitochondrial respiratory complexes by peroxynitrite. Recently, however, our laboratory has obtained data to suggest that ... WebAug 31, 2024 · Therefore, although data are very limited, cytopathic dysoxia related to impaired mitochondrial respiration appears not to widen the Pv-aCO 2 gap. The Pv-aCO 2 gap in sepsis. Ongoing tissue dysoxia with persistent lactic acidosis is a hallmark of sepsis, and associated with a poor prognosis. Although a hyperdynamic circulation is …
Webincrease the intravascular coagulation, the blood glucose. this leads to clotting risk and increased amounts of cytopathic dysoxia= organ failure decrease in fibrinolysis (more clots), decreased circulatory control in decreased endothelial integrity (allows more bugs to enter)= organ failure effects of TNF and Il on the body WebJun 11, 2015 · • Cytopathic dysoxia occurs when oxygen delivery is normal but cellular pathophysiology prevents utilization of oxygen as the terminal electron transport acceptor. In 1920, Haldane was credited with the observation that hypoxemia not only stops the [respiration] machine, but wrecks the [respiration] machinery as well.
WebTherefore “dysoxia” is used to describe any of the three states. This section reviews examples of abnormal cellular respiration using common clinical scenarios, including … WebMar 1, 2024 · Considered that cardiovascular dysfunction often happens in sepsis and ATP breakdown increases in cardiovascular dysfunction, it can be speculated that the increase of ATP breakdown in RBC is related to the decrease of ATP concentration in RBC in sepsis. In addition, a massive increase of ROS is seen in sepsis [27].
WebApr 25, 2024 · Profound impairment in cellular oxygen consumption, referred to as cytopathic dysoxia, is one of the pathological hallmarks in the lungs of patients with pathogen-induced acute lung injury (ALI). However, the underlying mechanism for this functional defect remains largely unexplored.
