PaCO2 is partial pressure of carbon dioxide (CO2), a measure of how well the lungs are _________ CO2 produced by cells.
PaCO2 is partial pressure of carbon dioxide (CO2), a measure of how well the lungs are excreting CO2 produced by cells.
__________ PaCO2 indicates CO2 accumulation in blood (more carbonic acid) caused by ____ventilation
__________PaCO2 indicates excessive CO2 excretion (less carbonic acid) through ____ventilation
Increased PaCO2 indicates CO2 accumulation in blood (more carbonic acid) caused by hypoventilation
Decreased PaCO2 indicates excessive CO2 excretion (less carbonic acid) through hyperventilation.
HCO3– is concentration of the base (alkaline substance) __________, a measure of how well the _______ are excreting metabolic acids.
HCO3– is concentration of the base (alkaline substance) bicarbonate, a measure of how well the kidneys are excreting metabolic acids.
________ HCO3– indicates that the blood has too few metabolic acids;
_________ HCO3– indicates that the blood has too many metabolic acids.
Increased HCO3– indicates that the blood has too few metabolic acids;
decreased HCO3– indicates that the blood has too many metabolic acids.
