Adult Respiratory Distress Syndrome
ARDS is caused by small blood vessels that leak fluid into the small air sacs of the lungs. The fluid in the sacs blocks oxygen from passing into the body.
Direct injuries that may lead to ARDS are:
- Sepsis of the lungs
- Breathing regurgitated stomach matter
- A bruise of the lung
- Breathing smoke or certain chemicals
- Respiratory syncytial virus
Indirect injuries that may lead to ARDS are:
- Severe injury, such as a heavy blow to the chest
- Swelling of the pancreas
- Drug overdose
- A large blood transfusion
The doctor will ask about your symptoms and health history. A physical exam will be done. Tests will be done if you are not able to communicate.
Blood tests will be done to look for low oxygen levels, infection, and signs of heart failure .
Pictures will be taken of the chest. This can be done with:
- Chest x-ray
- CT scan of chest
The underlying cause will be treated.
The goal of treatment is to help promote breathing. Choices are:
- Mechanical ventilation —a machine will move air in and out of the lungs
- Non-invasive mask mechanical ventilation—a mask will deliver air from a ventilator to the lungs
- Oxygen therapy —a mask or tube will deliver oxygen through the nose
- Extracorporeal membrane oxygenation (ECM)—advanced breathing and heart support (not as common)
