1) Respiratory acidosis-occurs when blood pH falls as a result of decreased respiration. When respiration is restricted, the concentration of dissolved carbon dioxide in the blood increases, making the blood too acidic. Such a condition can be produced by asthma, pneumonia, emphysema, or inhaling smoke.
2) Respiratory alkalosis-occurs from excessive breathing that produces an increase in blood pH. Hyperventilation causes too much dissolved carbon dioxide to be removed from the blood, which decreases the carbonic acid concentration, which raises the blood pH. Often, the body of a hyperventilating person will react by fainting, which slows the breathing.
3) Metabolic alkalosis- occurs when alkaline meterials are released into the blood causing an increase in blood pH. This can also be result of ingestion of alkaline materials. Again, the body usually responds to this condition by slowing breathing, possibly through fainting.
