Restrictive lung diseases cause a decrease in lung volume. Obstructive lung diseases trap air in the lungs and therefore increase lung volume. FEV1 is the forced expiratory volume in one second or the volume of air that can forcibly be blown out in one second, after full inspiration. FVC is the forced vital capacity or the volume of air that can forcibly be blown out after full inspiration and expiration. Both these values can be measured by spirometry. The ratio between the FEV1 and FVC can help distinguish between restrictive and obstructive lung diseases.Restrictive lung diseases can be caused by either poor breathing mechanics (a result of conditions like myasthenia gravis, obesity, and scoliosis) or can result from interstitial lung disease such as pneumoconioses or ARDS. Lung volume decreases in restrictive lung disease and the FEV1/FVC ratio is normal to increased (ie. greater than 80%) due to a significant decrease in forced vital capacity (FVC). Obstructive lung disease is characterized by airway obstruction and it is associated with inflammation of the airways and problems exhaling. Types of obstructive lung disease include asthma, bronchiectasis and COPD (chronic bronchitis and/or emphysema). Obstructive lung disease results in air trapping in the lungs which expands the lung volume over time. A decrease in the FEV1/FVC ratio suggests an obstructive condition. --------------------------------------------------------------------------------------------------------------------------- Join this channel to get access to perks: Sign up now on our website at https://members.drnajeeblectures.com/...    / @doctornajeeb   Follow us on Facebook :-   / drnajeeb   Follow us on Instagram :-   / drnajeeblectures
