<prompt> Which of the following is true about hypoxic hypoxia?Due to inadequate carrying capacityDue to inability to utilize oxygenDue to inadequate gas exchangeDue to slow circulation  <response>: 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 COPDHistotoxic HypoxiaInability of cells to utilize available O2 Cyanide poisoningStagnant HypoxiaDue to slow circulationCirculatory Shock Congestive heart failure
