Mixed Disturbance • Acidosis. – If the pH is low or AG is high , and the P a CO 2 is low or normal, a primary metabolic acidosis is present. The difference between the measured and the expected P a CO 2 is then used to identify a superimposed respiratory disorder. d – If the pH is low and the P a CO 2 is high, a primary respiratory acidosis is present. The difference between the measured and the expected [HCO 3 ] - is then used to identify a superimposed metabolic disorder. A low [HCO 3 ] - may also indicate a metabolic disorder with superimposed respiratory acidosis.
Mixed Disturbance (contd) • Alkalosis. – If the pH is high, a normal or high P a CO 2 indicates a primary metabolic alkalosis. The difference between the measured and the expected P a CO 2 is then used to identify a superimposed respiratory disorder. – If the pH is high, a low P a CO 2 indicates a primary respiratory alkalosis. The difference between the measured and the expected d[HCO 3 ] - is then used to identify a superimposed metabolic disorder.
