Features of progressive phase of shock -
ব্যাখ্যা
Explanation :
In progressive phase of shock -
Persistent oxygen deficit leads to intracellular aerobic respiration is replaced by anaerobic glycolysis with excessive production of lactic acid. The resultant metabolic lactic acidosis lowers the tissue pH, which blunts the vasomotor response; arterioles dilate, and blood begins to pool in the microcirculation.
Peripheral pooling not only worsens the cardiac output but also puts endothelial cells at risk for the development of anoxic injury with subsequent DIC.
With widespread tissue hypoxia, vital organs are affected and begin to fail.
