This causes the blood and other body fluids to become too acidic. Causes There are many causes of respiratory acidosis, including: Airway diseases, such as asthma and COPD AsthmaAsthma is a chronic disease that causes the airways of the lungs to swell and narrow.

This leads to a stable situation, because the kidneys increase body chemicals, such as bicarbonate, that help restore the body's acid-base balance.Acute respiratory acidosis occurs when carbon dioxide builds up very quickly, before the kidneys can return the body to a state of balance.Some people with chronic respiratory acidosis get acute respiratory acidosis when a serious illness worsens their condition and disrupts their body's acid-base balance. Symptoms Symptoms may include:Confusion Anxiety Easy fatigue Lethargy Shortness of breath Sleepiness Tremors (shaking) Warm and flushed skin Sweating Exams and Tests Your health care provider will perform a physical exam and ask about symptoms.You may have certain tests, including:Arterial blood gas (measures oxygen and carbon dioxide levels in the blood) Blood gasBlood gases are a measurement of how much oxygen and carbon dioxide are in your blood.
