Respiratory Acidosis Overview
Learn About Respiratory Acidosis
Respiratory acidosis is a condition that occurs when your lungs can’t remove all of the carbon dioxide produced by your body. This causes the blood and other body fluids to become too acidic.
Ventilatory failure; Respiratory failure; Acidosis - respiratory
There are many causes of respiratory acidosis, including:
- Airway diseases, such as asthma and COPD
- Lung tissue diseases, such as pulmonary fibrosis, which causes scarring and thickening of the lungs
- Diseases that can affect the chest, such as scoliosis
- Diseases that affect the nerves and muscles that signal the lungs to inflate or deflate
- Medicines that suppress breathing, including narcotics (opioids), and "downers," such as benzodiazepines, often when combined with each other or alcohol
- Severe obesity, which restricts how much the lungs can expand
- Obstructive sleep apnea
Chronic respiratory acidosis occurs over a long time. 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 may include:
- Confusion
- Anxiety
- Easy fatigue
- Lethargy
- Shortness of breath
- Sleepiness
- Tremors (shaking)
- Warm and flushed skin
- Sweating
Treatment is aimed at the underlying disease, and may include:
- Bronchodilator medicines and corticosteroids to reverse some types of airway obstruction
- Noninvasive positive-pressure ventilation (called CPAP or BiPAP)
- Oxygen if your blood oxygen level is low
- Treatment to stop smoking.
- Changing medicines when appropriate
If your case is severe, you may need to be put on a breathing machine (ventilator).

How well you do depends on the disease causing the respiratory acidosis.
Complications may include:
- Poor organ function
- Respiratory failure
- Shock
Severe acute respiratory acidosis is a medical emergency. Seek medical help right away if you have symptoms of this condition.
Call your provider if you have symptoms of lung disease that suddenly get worse.
DO NOT smoke. Smoking can lead to many severe lung diseases that can cause respiratory acidosis.
Losing weight may help prevent respiratory acidosis due to obesity (obesity-hypoventilation syndrome).
Be careful about taking sedating medicines, and never combine these medicines with alcohol.
Use your CPAP device regularly if it has been prescribed for you.
Summary: During apnoeic oxygenation there is a continuous raise in carbon dioxide with subsequent respiratory acidosis. The hypercapnia and respiratory acidosis have several dose-related effects on both the systemic and the pulmonary circulation and the heart that ultimately, if unrecognised, can result in cardiovascular collapse and fatal arrhythmias. In our knowledge, no studies have investigated the hae...
Summary: The study will be conducted as a single-center, prospective cohort study. The primary objective of this study is to investigate the responsiveness of sonographic parameters of diaphragm to detect change in Borg score for dyspnea during hospitalisation for AECOPD without respiratory acidosis.
