Exam Preview for 1448: Pulmonary Function Testing (PFT) Interpretat

Pulmonary Function Testing (PFT) Interpretation and Cases Studies

Please note: exam questions are subject to change.

1. A pulmonary function test may help identify/determine which of the following? Early identification of abnormalities in the respiratory system Determine the severity of a patient's impaired lung function Determine airway obstruction and restriction in the lung All of the above
2. What is a forced vital capacity (FVC) test? Test used to measure the normal expiratory flow Test used to determine the inhalation volume Test used to measure the total flow within 2 seconds Test used to determine the time at which the lung changes volume during extreme pulmonary function testing procedures
3. A volume decrease within the following measurements may indicate a restrictive disorder: RV, TLC, FRC FEV1, FEF25, FEF200 DLCO, RV, FEV1 FVC, FEV25, FEV1
4. What is the normal predicted range for FEV1? 80-120% 75-100% 15-85% 0-10%
5. If an obstructive process is present, PFT results will show a decrease in the FEV1/FVC ratio and: FVC FEV1 TLC RV
