Figure 29. “Effort Complete” Screen
For FVC efforts, the “% predicted” values display in color as follows:
Red:
% predicted values are below LLN.
Black: % predicted values are normal.
Green:
% predicted values are at least 100%.
11. Review the data.
For FVC tests, if desired, press Curve to alternate between curve types.
Decide whether to accept the effort. For help deciding, see the Spirometry Effort
Acceptability & Reproducibility poster.
12. Press the desired softkey.
•
Accept Effort
Saves the effort. See
•
Reject Effort
Deletes the effort.
In either case, the “ready to start effort” screen reappears (
Figure 28

If you are finished with this test, press Test Done.
Note
After each effort, a quality message appears on this screen, such as “Don’t
hesitate,” “Blow out longer,” or “Good effort.” For details, see
Note
The effort numbers increment with each new effort (FVC #1 becomes FVC
#2, and so on), even if some efforts were deleted, so the test record indicates
the patient’s total number of efforts.
