  Respiratory Acidosis | Caremark Health Resources
Respiratory acidosis is a condition in which a build-up of carbon dioxide in the blood produces a shift in the body's pH balance and causes the body's system to become more acidic.
Respiratory acidosis is an acid imbalance in the body caused by a problem related to breathing.
Respiratory acidosis can be caused by diseases or conditions that affect the lungs themselves, such as emphysema, chronic bronchitis, asthma, or severe pneumonia.

 Acidosis Summary
Acidosis is indicated by a lowering of blood pH that corresponds to an elevated hydrogen ion concentration in reaction to depletion in the normally counterbalancing alkaline sodium bicarbonate levels found in tissues and plasma.
With respiratory acidosis, a lowering of blood pH can result from inadequate ventilation of carbon dioxide (CO In many cases it is not the lack of oxygen that causes damage in obstructed airways, rather it is the acute (sudden) onset of severe acidosis caused by an inability to vent carbon dioxide.
The key to distinguish between respiratory and metabolic acidosis is that in respiratory acidosis, the CO is increased while the bicarb is either normal (uncompensated) or increased (compensated).

 Acidosis: Acid-Base Balance: Merck Manual Home Edition
Acidosis is excessive blood acidity caused by an overabundance of acid in the blood or a loss of bicarbonate from the blood (metabolic acidosis), or by a buildup of carbon dioxide in the blood that results from poor lung function or slow breathing (respiratory acidosis).
