Acid Base Flashcards
1
Q
Henderson Hasselbach
A
H + HCO3 H2CO3 CO2 + H2O
2
Q
Determine acid/base balance
A
- Acid or base
- Metabolic or respiratory
- Anion gap (Na - Bicarb - CL)
- Winters: pCO2 = [1.5 x Bicarb]+8+/- 2
- Corrected co2: delta anion gap/delta Bicarb gap
3
Q
Anion gap
A
Na-Bicarb-CL
>11 is a gap
4
Q
Winters formula
A
Determines respiratory compensation
pCO2 = [1.5 x Bicarb]+8+/- 2
pCO2 > winters = concomitant respiratory acidosis
5
Q
Delta gap and corrected bicarb
A
Delta gap (measured - 12)+ measured bicarb >24 = primary metabolic alkalosis
