what causes acute respiratory failure
Acute respiratory failure occurs when fluid builds up in the air sacs in your lungs. When that happens, your lungs canât release oxygen into your blood. In turn, your organs canât get enough oxygen-rich blood to function. You can also develop acute respiratory failure if your lungs canât remove carbon dioxide from your blood. Respiratory failure happens when the capillaries in your air sacs canât properly exchange carbon dioxide for oxygen. The condition can be acute or chronic. Acute respiratory failure causes you to experience immediate symptoms from not having enough oxygen in your body.
