Acids
|
Release H+
|
|
Bases
|
Accept H+
|
|
How is pH related to the H ion concentration.
|
pH is inversely related to H+ ion concentration.
|
|
Normal pH of ECF
|
7.35-7.45
|
|
Formula for pH
|
pH is a negative logarithm of H+ in mEq/L
|
|
Acid/Base exist as buffer pairs
|
Mix of weak acid and weak base
OR Mix of strong acid and strong base |
|
When acid is added to solution, pH will go
|
Down! less than 7.35
|
|
When base is added to solution, pH will go
|
Up! greater than 7.45
|
|
CO2
|
Primary Acid
CO2 is a gas bound to hemoglobin, but with water (from the lungs) it becomes a carbonic acid. |
|
HCO3
|
Primary Base
|
|
Bicarbonate Buffer System
|
Exchange of acids/bases within ICF and ECF to regulate pH
|
|
Hydrogen/Potassium Exchange System
|
Too much hydrogen - acidosis
Hydrogen will shift intracellular while potassium shifts out. Causes an increase in K+ levels (hyperkalemic) |
|
Stimulant to Respiration
|
An acute rise in PC02 is a powerful stimulant to respiration
|
|
Stimulant to Respiration for COPD patients
|
Decreased oxygen levels
