Question

A pre-hospital physician is considering the use of point-of-care blood gas analysis on a patient with respiratory failure. The device shows a pH of 7.18, PaCO2 of 9.8 kPa, PaO2 of 6.2 kPa, HCO3 of 26 mmol/L, and lactate of 1.2 mmol/L. What does this blood gas pattern indicate?

Accepted Answer

Acute respiratory acidosis - the low pH with high PaCO2 and normal bicarbonate indicates an acute process without renal compensation

Answer

Normal blood gas results

Answer

Metabolic acidosis with respiratory compensation

Answer

Chronic respiratory acidosis with acute decompensation

Answer

Mixed metabolic and respiratory acidosis
