Introduction
The PASPORT Spirometer allows students to collect accurate air-flow data from a pulmonary
function test (PFT). The subject breathes through a sanitary, single-use mouthpiece as data is
recorded and displayed on your computer or PASPORT interface. From the graphed data
students can measure tidal volume, forced expiratory volume, and other important lung
volumes and capacities.

Page 2: Data Collection
Spirometer How it works How it works When the test subject breathes through the mouthpiece, a screen in the mouthpiece induces a minute resistance to the air flow. This resistance leads to a pressure differential across the screen that is measured via two air lines that lead to a differential pressure transducer in the electronics enclosure. - Page 3 Model No. PS-2152 Data Collection Pulmonary Function Test Procedure 1. Use a nose clip or have the test subject hold his or her nose to ensure that all breathing is done through the mouth. 2. Hold the mouthpiece of the Spirometer stationary and away from air currents (including expired air).
- Page 4 Spirometer Data Collection Procedure Notes Observing the following conditions will allow you to collect consistent and accurate data. • You may need to run the test a few times in order to get satisfactory data. • The subject should sit up or stand comfortably. •...
- Page 5 Model No. PS-2152 Interpretation of PFT Data Interpretation of PFT Data Total Flow vs. Time 1 sec. Total Flow is the net volume of air that flows out from the lungs through the Spirometer, equal to the total expired volume minus the total inspired volume.
- Page 6 Spirometer Interpretation of PFT Data Lung Volume vs. Time 1 sec. Lung Volume is the constantly-changing amount of air in the lungs. A spirometer can measure how it changes, but cannot directly measure its absolute value. Lung volume can be calculated if one of two specific absolute volumes, residual volume (RV) or functional residual capacity (FRC), is known or estimated.
