Episode description
Contributor: Nick Tsipis, MD
Educational Pearls:
- pH 7.45=alkalemia
- If pH low and pCO2 high, indicates a respiratory acidosis
- If pH low and pCO2 low, indicates metabolic acidosis
- After determining type of acidosis, check bicarb to determine compensation for acidosis and check electrolytes to calculate anion gap
- Metabolic acidosis can present with tachypnea (Kussmaul breathing) and hypotension due to loss of catecholamine function and suboptimal cardiac function at low pH
- Treat with IV fluids and address the underlying cause, limited role for bicarb
