WebA class of lung diseases characterized by an obstruction to air flow leaving the lungs. Types of obstructive lung disease include. bronchiectasis. chronic bronchitis. emphysema. asthma. Pathophysiology of Obstructive Lung Disease. Obstruction of air leaving the lungs leads to ↑ trapped air in the lungs which results in. Key spirometry measurements include the following: 1. Forced vital capacity (FVC).This is the largest amount of air that you can forcefully exhale after breathing in as deeply as you can. A lower than normal FVC reading indicates restricted breathing. 2. Forced expiratory volume (FEV).This is how much air you can force from … See more Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you … See more Your doctor may suggest a spirometry test if he or she suspects your signs or symptoms may be caused by a chronic lung condition such as: 1.

WebThe spirometry results are consistent with obstructive pulmonary disease. This is because the pre-bronchodilator % Predicted values for FVC (93%), FEV1 (64%), and FEV1/FVC (69%) are significantly lower than the predicted values, indicating obstruction of air flow. WebIn pulmonary function testing, a post-bronchodilator FEV1/FVC ratio of <0.70 is commonly considered diagnostic for COPD. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) system categorises airflow limitation into stages. In patients with FEV1/FVC <0.70: GOLD 1 - mild: FEV1 ≥80% predicted.
