Determine whether a patient with an obstructive disease pattern has evidence of hyperinflation or air trapping. IF restrictive pattern, you’re going to want to get DLCO b/c it tells you whether the restriction is due to parenchymal disease (which will change your management), or NM, pleural or CW disease. Restrictive lung disease is made up of intrinsic lung disease (causes inflammation and scarring (interstitial lung diseases) or fill the airspaces w/ debris, inflammation (exudate); extrinsic causes are chest wall or pleural diseases that mechanically compress the lung and prevent expansion. Since infants aren’t capable of breathing on demand for a test, special equipment has been created to measure their lung function. Physiologic abnormalities that can be measured by pulmonary function testing include obstruction to airflow, restriction of lung size, and decrease in transfer of gas across the alveolar–capillary membrane. You can change your ad preferences anytime. Different pulmonary function tests (PFTs) are used to evaluate the physiologic processes of the respiratory system. Example of someone grabbing trachea—causes problems w/ inspiration and expiration = fixed obstruction. Spirometry is used to screen for diseases that affect lung volumes. This test measures the amount of air the lungs can hold. The test also measures how forcefully one can empty air from the lungs. Pulmonary Function Tests."
