Acute alveolar pneumonitis, also known as acute interstitial pneumonitis, is a type of lung inflammation that affects the small air sacs (alveoli) in the lungs. It is a severe form of acute respiratory distress syndrome (ARDS) that can cause rapid breathing, low blood oxygen levels, and respiratory failure.
The condition can be caused by various factors, including viral infections, bacterial infections, and exposure to toxins or other irritants. Symptoms of acute alveolar pneumonitis include shortness of breath, cough, fever, fatigue, and chest pain.
Diagnosis is typically made through imaging tests, such as a chest X-ray or CT scan, and a physical examination. Treatment may include oxygen therapy, mechanical ventilation, and medications such as corticosteroids to reduce inflammation.
Acute alveolar pneumonitis can be a life-threatening condition and requires immediate medical attention.
