1

The very serious business of recognising respiratory and metabolic acidaemia and alkalosis

And I mean serious.

2

pH - D pCO2 - UHCO3- - -/-pO2 - DD - DownU - Up -/- - No change

• Hypoventilation means raised pCO2 • Hyper capnia -> Low pH • HCO3- unchanged • Respiratory acidaemia

3

pH - D/-pCO2 - UHCO3- - UPO2 - D

• Compensated (partially or fully) respiratory acidaemia • Kidneys have increased HCO3- • Increases buffering of H+ ions caused by increased pCO2

4

pH - UpCO2 - DHCO3- - -/-PO2 - -/U

• Respiratory alkalaemia • Hyperventilation has lower pCO2 • Hypocapnia -> High pH • HCO3- unchanged

5

pH - UpCO2 - DHCO3- - DPO2 - U

• Compensated (partially or fully) respiratory alkalemia • Kidneys have decreased HCO3- • Decreased buffering of H+ ions

6

pH - DpCO2 - -/-HCO3- - DPO2 - -/-Anion Gap - U

• Metabolic acidosis • Decreased HCO3- -> Less buffering of H+ ions Increase in unmeasured anions

7

pH - DpCO2 - DHCO3- - DPO2 - UAnion gap - U

• Compensated (partially or fully) metabolic acidosis • Increased respiratory rate -> Hypocapnia -> Raised pH • Anion gap still increased

8

pH - UpCO2 - -/-HCO3- - UPO2 - -/-

• Metabolic alkalosis

9

pH - UpCO2 - U HCO3- - UPO2 -D

• Compensated metabolic alkalosis • Decreased respiratory rate -> Hypercapnia • Decreased pH Can only partially compensatte
