There is usually one particular cause in respiratory alkalosis that is hyperventilation. There are two main common causes also, these include panic attacks and anxiety. Other possible causes are heart attack, pain, drug use, asthma, COPD, infection, pulmonary embolism, and pregnancy. Some symptoms that occur with someone who has this condition are dizziness, bloating, light-headedness, numbness, muscle spasms, confusion, dry mouth, tingling in arms, heart palpitations, and feeling short of breath. Compensatory Mechanisms. In respiratory alkalosis, the intracellular buffering response stimulates a slight decrease in HCO3-. The main organ for compensation is the kidney. The renal response is somewhat slow and may take up to 2-3 days for a maximal response to be reached. Last, with a drop in bicarbonate, the extracellular pH returns only partially to the normal range. Treatment. Treatment for respiratory alkalosis is more aimed towards the underlying conditions. Things such as breathing into a paper bag or using a mask that helps rebreathe carbon dioxide usually helps reduce symptoms. There are no medical treatments other than antidepressants for people who do not respond to the other
