This implied that V˙o2 was dependent on ( D˙o2) over a much wider range than normal and that there was a persistent oxygen debt caused by ischaemic hypoxia. This was termed ‘pathological oxygen supply dependency’. However, many of these studies were complicated by methodological problems ...
How may the circulatory system influence how often, or low long, an organism goes into oxygen debt? What is the oxygen pressure in alveoli, arterial blood and tissue? What is the condition of a person's lungs when they have emphysema?
oxygen debt(seequot.1923);oxygen lance(seelancen.18);oxygen mask, a mask fitting over the nose and mouth through which oxygen or oxygen-enriched air may be supplied for breathing;oxygen tent, a tent-like enclosure for placing over a patient in order to provide him with an oxygen-enriched...
H2S and NH4below 65 m. We then calculate how much oxygen is needed to eliminate all H2S and NH4below this depth, define this as an oxygen debt, and discuss the utility of this approach for describing the oxygenation state of the Baltic...
this dependence between DO2and VO2is observed is called the critical oxygen delivery. Below this value, the anaerobic metabolic pathway is used to ensure adequate energy production, resulting in the formation of lactic acid, a marker of deficiency of the aerobic pathway and tissue oxygen debt. ...
Two factors would explain this absolute priority for succinate consumption: (1) The very same enzyme succinate dehydrogenase (complex II) ensures either building of the succinate oxygen debt or electron injection in the respiratory chain. In comparison, the pathway from lactic acid to electron supply...
The magnetic susceptibility of blood is determined by the volume fraction of the paramagnetic deoxyhemoglobin in red blood cells and scales linearly with (1 – HbO2). Under normal conditions, tissue oxygen debt created by periods of ischemia due to arterial occlusion is followed by reactive hyper...
requires associated, time-consuming, cross-matching [35,36] and may conflict with religious beliefs [37,38]. Therefore, blood substitutes that can fully and completely or partially replace the oxygen-carrying functions of RBCs have emerged. These substitutes can be classified into perfluorocarbons ...
Enhancing the antioxidant level of plant cells either en- dogenously through genetic engineering or by an exogenous application can strengthen the defense system of the plant and rescue them from the debt of environmental stress. 5.1. Enzymatic Antioxidants An enzymatic antioxidant such ...
A CO 2 -debt of the cardiac muscle due to previous carboxilation and CO 2 release as well as alterations in myocardial metabolism could be responsible for this.The increase in heart rate of average 24% noted at high dosages is considered the expression of the drop in blood pressure ...
