Respiratory acidosisis characterized by a decrease in pH and an increase in Pco2, which develop because of decreased effective alveolar ventilation. CO2diffuses through the lungs much more readily than oxygen; thus diseases that compromise ventilation normally result in decreases in PO2before significant...
RespiratoryacidosisAcidosisA pathologic condition of acid accumulation or depletion of base in the body. The two main types are respiratory acidosis and metabolic acidosis, due to metabolic acid build up.Respiratory Acidosiscan occur with severe ARDS. ...
Poor physiologic management of CO2and bicarbonate can lead to the conditions of respiratory acidosis and respiratory alkalosis. Respiratory acidosis is characterized by higher blood concentrations of CO2and H+, caused by hypoventilation or decreased rate of breathing. Hypoventilation can have acute or chro...
Synonyms Hypercapnia Definition and Characteristics Respiratory acidosis (RA) is an acid-base disorder characterized by a primary elevation of arterial carbon dioxide tension (PaCO 2 ). Compensation for RA involves an increase in plasma HCO 3 that occurs in two phases: (i) a rapid response from ...

The optimal acid-base balance is maintained by chemical buffers, biologic activities of the cells, and effective functioning of the lungs and kidneys. The opposite of acidosis is alkalosis. adj., adj acidot´ic.Acidosis usually occurs secondary to some underlying disease process; the two major ...
Hypercarbic respiratory failure is characterized by alveolar hypoventilation and respiratory acidosis. Hypercarbic respiratory failure results from decreased minute ventilation and/or increased physiologic dead space. Conditions associated with hypercarbic respiratory failure include neuromuscular diseases (...
