which factor can induce a rightward shift of the oxyhemoglobin dissociation curve?

PCO2 increase
temperature decreases
PO2 increases
PH increases

in a cyanosis patient the color of nail bed is?

cherry red
more redder than the normal

when the oxyhemoglobin dissociation curve shift to rightward?

(CaO2-CvO2) increases
(CaO2-CvO2) decreases
blood O2 capacity inceases
in arterial blood O2 content increases

in which kind hypoxia does (CaO2-CvO2) increases?

hypotonic hypoxia
histogenous hypoxia
hypoxic hypoxia
circulatory hypoxia

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

which parameter can illustrate the quantity of O2 used by tissure?


which one can be the reason of enterogenous cyanosis?

CO poisoning
nitrite poisoning
cyanide poisoning
intestinal obstruction

in serious hypoxia the change of intracellular ion concentration is?

[H+]i dicreases
[K+] i increases
[Na+]i increases
[Na+]i decreases

which kind hypoxia can lead CvO2 increases?

isotonic hypoxia
hypotonic hypoxia
histogenous hypoxia
circulatory hypoxia

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

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

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
