Which of the following is true about hypoxic hypoxia?
Ans. C Due to inadequate gas exchangeRef: Ganongy 25th ed. pg. 651* Hypoxic hypoxia is due to inadequate gas exchange, in which the oxygen content of arterial blood and PO2 are reduced. Example: COPD, High altitude.Types of Hypoxia and causesType of hypoxiaPathophysiologyExampleAnemic HypoxiaDue to reduced oxygen carrying capacityAnemia (Reduced RBC, Reduced Hb); CO poisoningHypoxic HypoxiaDue to Inadequate gas exchangeHigh altitude Respiratory disease (COPD)Histotoxic HypoxiaInability of cells to utilize available O2 Cyanide poisoningStagnant HypoxiaDue to slow circulationCirculatory Shock Congestive heart failure
