What causes respiratory failure?
Respiratory failure is the inability of the respiratory system to supply oxygen or remove carbon dioxide, resulting in low blood oxygen or high blood carbon dioxide levels. Multiple conditions can cause one or both of these problems. Respiratory failure can transpire quickly as the result of trauma, injury, drug or alcohol overdose, or inhalation of carbon monoxide. Chronic, or long-term, respiratory failure is commonly caused by chronic obstructive pulmonary disease (COPD), neuromuscular disease, or even morbid obesity.
Causes of acute respiratory failure
A number of conditions may cause acute respiratory failure, many of which are life-threatening or serious conditions. Examples include:
- Acute asthma attack
- Acute respiratory distress syndrome (life-threatening respiratory condition)
- Carbon dioxide poisoning
- Chest trauma
- Drug or alcohol overdose
- Lung contusion (bruising)
- Near drowning
- Pneumothorax (collapsed lung)
- Pulmonary embolism (blockage of one of the main arteries going to the lungs)
- Smoke or toxin inhalation
Causes of chronic respiratory failure
A number of conditions may cause chronic respiratory failure, many of which are serious conditions. Examples include:
- Amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig’s disease; a severe neuromuscular disease that causes muscle weakness and disability)
- Chronic obstructive pulmonary disease (COPD), including emphysema and chronic bronchitis
- Cystic fibrosis (buildup of thick mucus in the lungs and digestive tract)
- Guillain-Barré syndrome (autoimmune nerve disorder)
- Morbid obesity
- Myasthenia gravis (autoimmune neuromuscular disorder that causes muscle weakness)
- Pulmonary fibrosis (damaged and scarred lung tissue)
- Sarcoidosis (inflammatory disease most commonly affecting the lungs, skin and eyes)
- Severe curvature of the spine (scoliosis)
What are the risk factors for respiratory failure?
- Aspiration of stomach contents
- Combination of drug and alcohol use
- Multiple blood transfusions
- Severe obesity
- Chronic obstructive pulmonary disease
What is respiratory failure?
Respiratory failure is the inability of the respiratory system to adequately supply fresh oxygen or remove carbon dioxide, resulting in low blood oxygen or high blood carbon dioxide levels, respectively. Multiple conditions can cause one or both of these problems. Acute or sudden respiratory failure can happen as the result of trauma, injury, drug or alcohol overdose, or inhalation of carb...

What are the symptoms of respiratory failure?
Respiratory failure causes insufficient oxygenation or ventilation and can cause a number of symptoms, which can be severe.
Common symptoms of respiratory failureRespiratory failure is accompanied by a number of symptoms including:

- Confusion or loss of consciousness

How is respiratory failure treated?
Treatment for respiratory failure begins with seeking medical care from your health care provider. The goals of treatment for respiratory failure are to increase oxygenation and improve ventilation. Treatment depends on the severity of the respiratory failure and the cause. Acute respiratory failure treatment will address the underlying cause and include ventilation and oxygenation as needed.
