<prompt> Among which hypoxia AV O2 difference is max -HistotoxicStagnantHypoxicAnemic  <response>: Ans. is b i.e.. Stagnant HypoxiaArterial O2 PaO2Venous O2 PvO2HypoxicAnemicHistoxicNormalStagnantNormalo Thus, stagnant hypoxia has maximum arterio-venous O2 difference as Arterial O2 is normal but venous O2 is decrease - Increasing the difference. This is because more O2 is extracted by tissues due from stagnant blood.HYPOXIATypesSingle best testPAO2Pa O2O2 tension ordissolved O2O2 consent03 carrying capacityA-V-O2differencesaturaSa O2Stimulaof PCROther RemarHypoxicPa O2;N 2,3 DPG, O2 therapy usefulAnemicO2, contentor HbNNN 2,3 DPG shift to right, hyperkinetic circulation, turbulenceStagnantA-V O2,differenceNNNN HistotoxicA-V O2.
