Types of acid/base imbalances
Acidosis and alkalosis – both metabolic & respiratory
Definition of metabolic imbalance
Change in amount of fixed acids or in bicarbonate levels
Examples of fixed acids
Lactic acid, hydrochloric acid, ketoacids
The volatile acid in the body is
Carbonic acid
Carbonic acid is created through:
The hydrolysis of carbon dioxide, aka CO2 and water
Carbonic acid dissociates into:
Hydrogen and bicarbonate ions
Carbonic acid's concentration can be altered via
Respiration
For every 20 carbonic acid molecules formed, the body saves:
20 bicarbonate ions and 1 hydrogen ion; kidney excretes the rest
Fixed acids are termed fixed because:
They cannot be eliminated by changing respiration
In metabolic acidosis, what happens:
PH decreases. Either acid increases or bicarbonate decreases.
In metabolic alkalosis, what happens:
PH increases. Either acid decreases or bicarbonate increases.
What does PaCO2 stand for?
Partial concentration/pressure of CO2 in arterial blood
In respiratory imbalance:
Change in PacCO2
Cause of respiratory acidosis:
Accumulation of carbonic acid due to too much CO2
In respiratory acidosis, what happens:
CO2 undergoes hydration; hydrogen is released from carbonic acid; pH decreases
