What happens when pCO2 is high?
pCO2 gives a Respiratory components indicating blood gas results. High and low values indicate hypercapnia (hypoventilation) and hypocapnia (hyperventilation), respectively. High pCO2 is compatible with respiratory acidosis and low pCO2 is compatible with respiratory alkalosis.
