CO2 and Acid-Base Balance (PK7) Flashcards
1
Q
Henderson-Hasselbach equation
A
pH = pK + log[A-] / [HA]
2
Q
Why is the CO2/HCO3- buffer system used when considering blood?
A
- High concentrations
- Easy to measure
3
Q
What are each of CO2 and HCO3- regulated by?
A
- CO2 = lungs
- HCO3- = kidneys
4
Q
Modified Henderson-Hasselbach equation using [HCO3-] and PCO2
A
pH = pK’ + log[HCO3-] / [PCO2 x 0.23 (solubility constant)]
