Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces. This disrupts the body's acid-base balance. Body fluids become too acidic

Alternative Names

Ventilatory failure; Respiratory failure; Acidosis - respiratory

Causes and risk factorsCauses of respiratory acidosis includeDiseases of the airways such as asthma and chronic obstructive lung disease, which send air into and out of the lungs
Diseases of the chest such as scoliosisthat make the lungs less efficient at filling and emptying
Disease of the nerves and muscles that "signal" the lungs to inflate or deflateDrugsincluding powerful pain medicines such as narcotics, and "downers" such as benzodiazepines, especially when combined with alcohol
Severe ObesityChronic respiratory acidosis occurs over a long period of time. This leads to a stable situation, because the kidneys increase chemicals that help restore the body's acid-base balance

Acute respiratory acidosis is a severe condition in which carbon dioxide builds up very quickly and before the

Symptoms

Confusion
Easy fatigue
Lethargy
Shortness of breath
Sleepiness

Signs and tests

A chest x-ray or CT scan is a helpful way of checking the lung's appearance without having to biopsy it

Pulmonary function tests are a series of breathing tests that evaluate lung capacity

An arterial blood gas test involves having blood drain and directly measuring the amounts of oxygen, carbon dioxide, and acids

TreatmentTreatment is aimed at the underlying lung disease, and may include

Bronchodilator drugs to reverse some airway obstruction
Methods to stop smoking
Non-invasive positive-pressure ventilation sometimes called CPAP or BiPAP or mechanical ventilation if needed
Oxygen if the blood oxygen level is low

prognosis

How well you do depends on the disease causing the respiratory acidosis

Complications

Poor organ function
Respiratory failure
Shock

Prevention

Do not smoke. Smoking leads to the development of many severe lung diseases that can cause respiratory acidosis

Losing weight may help prevent obesity hypoventilation syndrome

Be very careful about taking sedating medicines, and never combine these medicines with alcohol
