I need the answer as soon as possible
Under normal conditions, and
regarding blood gases, choose the
INCORRECT statement:
O a. In early lung disease, arterial
PO2 is affected before arterial
PCO2.
O b. Most of the 02 in blood is
carried as oxyhemoglobin
O c. 02 crosses the respiratory
membrane easier than CO2
o d. Most of the CO2 in the blood
is transported as HCO3-
(bicarbonate)
O e. In plasma, dissolved [Co2] is
more than dissolved [02]
In advanced emphysema (severe
COPD), choose the CORRECT
statements
a. FEVI.0 is less than 80% but
more than 60% of the
predicted value
O b. FEVI.O is less than 40% of the
predicted value
O c. Inspiration becomes passive
O d. Lung compliance is lower
than normal
e. FEVI.O is less than 60% but
more than 40% of the
predicted value
