2/12

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

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
