is important, because untreated pneumonitis can lead to lung scarring and permanent difficulty of breathing. 

Symptoms 症状
The most common signs and symptoms of pneumonitis are: 
• Cough 
• Difficulty of breathing 
• Fever 
• Chills 
• A general feeling of being unwell 

Other signs and symptoms depend on the type of pneumonitis that you develop. For example, if you breathe in chlorine gas, causing chemical pneumonitis, you may experience a burning feeling in your chest. Chest pain is a feature of radiation-induced pneumonitis. Signs and symptoms of pneumonitis may last anywhere from several hours to days or even longer. 

Tests and diagnosis 测试和诊断
• Pulmonary function test- this refers to a series of tests that evaluate how well your lungs are working. A common pulmonary function test, called a spirometry, measures the amount of air that you’re able to inhale and exhale in a specific period of time. Your doctor may also measure how efficiently your lungs transfer gases from the air into the bloodstream. 
• Bronchoscopy- is a procedure used to view your airways and collect samples from your lungs. In order to make you as comfortable as possible during the procedure, your doctor will spray an anesthetic in the back of your mouth and throat and will give you medication through a vein in your arm to help you relax. A flexible tube called a broncoscope is passed through your mouth or nose and then into your lungs. 
Complications 

Pneumonitis that goes unnoticed or untreated can cause irreversible lung damage. Normally, air sacs within your lungs stretch and relax with each breath. Chronic inflammation of thin tissue lining of each air sac can make the air sacs scar and become inflexible. This is called pulmonary fibrosis. In severe cases, pulmonary fibrosis can cause heart failure, respiratory failure and death. 

Treatments and drugs 治疗和药物
If you have hypersensitivity or chemical pneumonitis, avoiding allergens is a common-sense approach to treatment. By eliminating exposure to the allergen or chemical irritating your lungs, you’ll likely notice that your symptoms lessen. 
In severe cases of pneumonitis, treatment includes: 
• Corticosteroids. Drugs that reduce inflammation can help relieve the symptoms of pneumonitis. Corticosteroids are usually taken as a pill in your lungs. However, corticosteroid use also increases your risk of developing infections and is associated with the thinning of bones. 
• Antibiotics. Having pneumonitis makes you more susceptible to developing bacterial infections in your lungs. The type of antibiotic you’ll receive depends on the bacteria causing infection. Antibiotic therapy may be given through a vein in your arm or taken as a pill. 
• Oxygen therapy. People who have chronic pneumonitis with fibrosis and can’t breathe well usually require oxygen therapy. Some people need therapy constantly, while others might need it only during exercise or sleep.
