Pulmonary Fibrosis Glossary
Find definitions of common pulmonary fibrosis terminology.
Bronchoalveolar lavage (BAL)
A medical procedure in which an instrument (bronchoscope) is passed through the mouth or nose into the lungs. Fluid is then squirted into a small part of the lung and the fluid is collected. It is then examined under a microscope for signs of disease.
Forced Expiratory Volume (FEV) and Forced Vital Capacity (FVC)
FEV measures how much air a person can exhale during a forced breath. Forced vital capacity (FVC) is the total amount of air exhaled during the FEV test.
GAP Model or GAP Risk Assessment System
A prediction tool that estimates prognosis in patients with idiopathic pulmonary fibrosis. It looks at factors such as gender, age, and physiology which includes lung function.
Gastroesophageal Reflux Disease (GERD)
A digestive disorder in which stomach acid travels up into the esophagus and throat. It can cause heartburn, indigestion and even injury to the esophagus. Sometimes it is painless. The acid can also cause throat irritation, post-nasal drip, hoarseness, chronic cough, chest congestion and lung inflammation. Some pulmonary fibrosis patients also have GERD.
High-Resolution Computed Tomography Scan (HRCT)
A type of computed tomography (CT) that uses specific techniques to create a very detailed picture. It is commonly used to diagnose interstitial lung disease, including pulmonary fibrosis.
Care aimed at making the patient more comfortable and improving quality of life. Hospice care always includes palliative care, but palliative care can be given at any stage of a disease. Palliative care is provided by a team of specialists including palliative care doctors, nurses and social workers. Massage therapists, pharmacists, nutritionists, spiritual care advisors and others may also be part of the team.
Video Assisted Thoracoscopic Surgery (VATS)
A type of lung surgery that typically involves one to four small incisions to access the inside of the chest. The surgeon uses a camera to visualize the lung and special instruments to perform the surgery. This can also be done with the help of a surgical robot. VATS can be used to perform many different procedures such as collecting tissue for a biopsy.
