1.4- Acid-Base Balance Flashcards
1
Q
What is the average arterial blood pH?
A
7.4
2
Q
What are the conditions termed for values outside of normal pH?
A
Normal blood pH: 7.3-7.45
Add hydrogen ions: academia pH <7.35
Reduce hydrogen ions: alkalemia >7.45
3
Q
What are acids?
A
Volatile & non-volatile
Sulfuric acid
Phosphoric acid
Organic acids
4
Q
What are buffers?
A
HCO3- Non HCO3-
Buffer is any substance that consumes or releases H+ helping to stabilize pH
Buffer value of a solution is the quantity of H+ that can be added or removed causing a change of 1 pH unit
Whole blood in the absence of CO2 and HCO3- is ~25mM/pH
