(CaO2-CvO2) increases (CaO2-CvO2) decreases blood O2 capacity inceases in arterial blood O2 content increases 2/12 in which kind hypoxia does (CaO2-CvO2) increases? hypotonic hypoxia histogenous hypoxia hypoxic hypoxia circulatory hypoxia 3/12 which kind hypoxia can lead CvO2 increases? isotonic hypoxia hypotonic hypoxia histogenous hypoxia circulatory hypoxia 4/12 which parameter can illustrate the quantity of O2 used by tissure? CaO2 CvO2 SvO2 CaO2-CvO2 5/12 in a cyanosis patient the color of nail bed is? brown cherry red more redder than the normal bluish pale 6/12 a result of blood test is : Pao2 65mmHg,CO2max 20 ml/dL, CaO2 18 ml/dL, SaO2 90% ( CaO2-CvO2) 4ml. which kind hypoxia? hypotonic hypoxia histogenous hypoxia isotonic hypoxia hemic hypoxia 7/12 which factor can induce a rightward shift of the oxyhemoglobin dissociation curve? [H+]dicreases PCO2 increase temperature decreases PO2 increases PH increases 8/12 which one has not relationship with oxygen content in artery? the quantity of Hb the function of lung oxygen capacity the state of internal respiration 9/12 why the nail bed in a patient of carbon monoxide poisoning is cherry red? O2 content of arterial blood increases O2 content of venous blood increases carboxyhemoglobin is bright red color PaO2 is normal 10/12 which one can be the reason of enterogenous cyanosis? CO poisoning nitrite poisoning cyanide poisoning intestinal obstruction 11/12 in serious hypoxia the change of intracellular ion concentration is? [H+]i dicreases [K+] i increases [Na+]i increases [Na+]i decreases 12/12 which describe about respiratory system is mistake in the early stage of acute hypotonice hypoxia? excitement of the respiratory center increases respiratory frequency increases the hypoxia is more serious the respiratory center is more excistement ventilation volume increases
