Physio: Acid Base Regulation Flashcards
Acid
H+ Donor
Base
H+ Acceptor
Acidosis
The excess addition of H+ to body fluids
Alkalosis
The excess removal of H+ from body fluids
Volatile acid
An acid derived directly from the hydration of CO2
Non-Volatile Acid
An acid NOT derived directly from the hydration of CO2
Titratable Acid
An acid that can lose H+ in an acid/base reaction
Acid-Base disorders manifest themselves as deviations in levels of either ________
Plasma CO2 or HCO3-
Can be caused by a primary disturbance of HCO3- or pCO2
Respiratory Acidosis
High pCO2
Respiratory Alkalosis
Low pCO2
Metabolic Acidosis
Low HCO3- (plasma)
Metabolic Alkalosis
High HCO3- (plasma)
Respiratory Disorders
Caused by over or under-ventilation
Primary uncompensated disorder
If only one of these is unchanged
Compensation exists when either pCO2 or HCO3- levels remain altered for a period of time
What is the log value of the dissociation constant for the bicarbonate buffer system?
