Q

Determine acid/base balance

A
  1. Acid or base
  2. Metabolic or respiratory
  3. Anion gap (Na - Bicarb - CL)
  4. Winters: pCO2 = [1.5 x Bicarb]+8+/- 2
  5. Corrected co2: delta anion gap/delta Bicarb gap

Q

Winters formula

A

Determines respiratory compensation
pCO2 = [1.5 x Bicarb]+8+/- 2
pCO2 > winters = concomitant respiratory acidosis
