60 A 55-year-old woman with severe pulmonary fibrosis undergoes pulmonary function testing. Which of the following findings is most likely in this patient? OA) Decreased FEV, FVC ratio B) Decreased lung compliance OC) Decreased work of breathing D) Increased expiratory reserve volume OE) Increased functional residual capacity F) Increased residual volume G) Normal total lung capacity
Pulmonary Fibrosis is a condition in which the lung tissues get damaged and scarred. Thickening and stiffness of the tissues makes it difficult for the lungs to function normally. The patient may experience shortness of breath that increases progressively with the condition. The damage to the lung tissues as the result of fibrosis is not repairable. Medical intervention aim to ease the symptoms and improve the quality of life.
Spirometry test measures three lung volumes which are are inspiratory reserve volume, tidal volume and expiratory reserve volume. These lung volumes are also called inspiratory capacity, vital capacity and functional residual capacity.This test cannot measure the residual volume. Pulmonary function test measure the lung function and capacity. This test measure how much air the lungs can hold and how much air is moved in and out of the lungs.
