tumor, or an injury due to an accident or intubation or tracheotomy. These are all
examples of an extrathoracic airway obstruction.
If the flow volume loop shows signs of UAO, the obstruction should be assessed and
located using flexible bronchoscopy (to view the obstruction)
Quality of Test Results
If you do not have the patient inhale at the end of the test, how can you be assured that
the patient expired fully or that the patient inhaled fully before they started the test? If a
patient performs a flow volume loop, the results of their expiratory volume and their
inspiratory volume should be within 10% of each other. If they are not, the appropriate
acceptability statement will display after the test is completed.
Post-Bronchodilator Tests
The following instructions assume you have already performed the Pre-BD test on the
patient and have administrated the bronchodilator.
Testing one patient at a time
From the View Report screen, you can select a bronchodilator from a list and then click
Post-BD to perform tests. Selecting Post-BD returns you to the testing screen. Post-BD
FVC tests are performed the same way as Pre-BD FVC tests. See Appendixes P and Q.
Testing more than one patient at a time
Select a patient from the patient list. Click New Test. Select Spirometry and click OK.
If you have performed a Pre-BD test on this patient, the program will display a list of test
type selections. To attach a Post-BD test to the existing Pre-BD test, use the default
