Abnormal Results of Pulmonary Function Studies
Pulmonary function tests (PFTs) are a group of breathing tests that measure how well the lungs are working. These tests are used to diagnose and monitor lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis. PFTs are non-invasive and painless, and they can be performed in a doctor's office or a hospital.
When a patient undergoes PFTs, the results are compared to normal values for their age, gender, and height. If the results are outside the normal range, it may indicate a problem with lung function. Abnormal results can be caused by a variety of factors, including lung diseases, smoking, and exposure to pollutants.
Types of Abnormal Results
There are several types of abnormal results that can be obtained from PFTs:
- Reduced Lung Function: This means that the lungs are not able to move air in and out as well as they should. Reduced lung function can be caused by a variety of factors, including asthma, COPD, and pulmonary fibrosis.
- Obstructive Lung Disease: This means that there is a blockage in the airways that makes it difficult to exhale. Obstructive lung disease is often caused by smoking or exposure to pollutants.
- Restrictive Lung Disease: This means that the lungs are not able to expand fully, which can make it difficult to inhale. Restrictive lung disease can be caused by pulmonary fibrosis, scarring of the lungs, or obesity.
Treatment for Abnormal Results
If a patient's PFTs show abnormal results, their doctor may recommend further testing to determine the cause of the problem. Treatment for abnormal lung function depends on the underlying cause. In some cases, medication may be prescribed to open up the airways or reduce inflammation. In other cases, lifestyle changes such as quitting smoking or avoiding pollutants may be recommended. In severe cases, surgery may be necessary to remove damaged tissue from the lungs.
In conclusion, PFTs are an important tool for diagnosing and monitoring lung diseases. If you are experiencing symptoms such as shortness of breath or coughing, talk to your doctor about whether PFTs may be appropriate for you.
