Method
- Primary disturbance (acidemia/alkalemia)
- Primary process (metabolic/respiratory)
- Presence of mixed disorder
- Increase PCO2 of 10, increases HCO3 by 1 (acute) or 3 (chronic)
- Decreased PCO2 of 10, decreases HCO3 by 2 (acute) or 5 (chronic)
- Increase HCO3 of 1, increases PCO2 by 0.7
- Decreased HCO3, add 15, result should equal PCO2 and number after decimal of pH
- Anion gap
