Usually a clip is placed on the nose to prevent any air from entering the nasal passages. The VA rating system depends mostly on spirometry results when evaluating a respiratory disorder.Ī spirometer is a hand-held device into which the individual breathes. Spirometry is the easiest, fastest, and most readily available method of function testing in outpatient clinics. The most common form of pulmonary function tests is spirometry. Once you arrive at your appointment, your healthcare provider will talk you through the steps of the test. Be sure to wear loose clothes so you can breathe comfortably. You should also have a light meal and limit fluid intake. This will likely include avoiding alcohol, smoking, caffeine, and heavy exercise within the hours leading up to the test. Your doctor will provide specific instructions to prepare for your pulmonary function test. What Can I Expect from Pulmonary Function Tests? These measurements show how effectively you’re able to breathe and how well your lungs are able to deliver oxygen throughout the body. PFTs can determine whether an obstructive or restrictive disease is present, and also determine the location of a defect.Ī pulmonary function test measures three aspects of lung function: Neuromuscular diseases, such as amyotrophic lateral sclerosis (ALS)Ī pulmonary function test (PFT) measures how much air can be inhaled and exhaled, and how much carbon monoxide can enter the bloodstream within a certain period of time.Ī veterans doctor typically performs a pulmonary function test when initially diagnosing the condition, and then periodically afterwards to gauge the severity of the condition.Interstitial lung disease (such as pneumonia).In some cases (interstitial lung diseases), autoimmune or rheumatologic diseases can cause progressive scarring of the lung tissue that lies in between and supports air sacs. Sometimes this can occur when there is stiffness in the chest wall, weak muscles or damaged nerves that restrict the expansion of the lungs. Usually restrictive diseases occur when there is stiffness in the lungs themselves. This type of lung condition is a result of the lungs being restricted from fully expanding. Restrictive disorders make it difficult to fill lungs with air. Chronic Obstructive Pulmonary Disease ( COPD), including emphysema and chronic bronchitis.Obstructive lung diseases make it more difficult to breath, especially with increased activity of exertion.Īs the rate of breathing increases, there is less time to breathe out all the air before the next inhalation. This is due to reduced elasticity of the lung airways, or some kind of obstruction (like mucus or inflammation). Obstructive disorders make it difficult to exhale all the air in the lungs.ĭamage to the lungs, or narrowing of the airways (bronchii) inside the lungs, cause air to be exhaled more slowly than normal. However, there several respiratory disorders do not fall under either of these categories, such as: Most respiratory disorders are grouped under one of these two categories. If the volume of air is reduced, the defect is restrictive. Putting it simply, if the air flow is impeded, the defect is obstructive. Routine spirometry testing measures two basic components: (1) air flow and (2) volume of air out of the lungs. Pulmonary function disorders are grouped into two main categories: obstructive and restrictive. Here’s what former military service members should know about pulmonary function tests and VA disability benefits for respiratory disorders. There are so many kinds of respiratory conditions, however, and the severity can vary so greatly, that the VA most often uses pulmonary function tests (PFTs) as a basis for its rating criteria. The VA’s rating schedule has been well-equipped to address all possible disorders of the nose and throat.
