About Pre- and Post-Testing
If desired, a spirometry test may include both pre- and post-efforts (FVC or SVC) to
measure the effectiveness of medication. The “before medication” and “after
medication” efforts may be uninterrupted or interrupted.
• Uninterrupted
If there is no interruption between pre- and post-efforts (that is, no other patient has
been tested and the electrocardiograph has remained on), the same screen continues
to display. You simply continue with the procedure.
• Interrupted
If there is an interruption (that is, another patient has been tested or the
electrocardiograph has been turned off), you need to recall the patient’s test-in-
progress before continuing.
About Effort Replacement
You can save up to 6 FVC and 6 SVC efforts per test (maximum total of 12 efforts). After
saving 6 efforts of a given type, the software compares each new effort with the saved
efforts. If the new effort is better than the worst saved effort, the worst effort is deleted
and the new one is saved. If the new effort is worse than all saved efforts, you are asked
whether you want to save it.
If 6 pre-efforts have been saved, the worst pre-effort is deleted when you add a post-effort
until you have saved 3 pre- and 3 post-efforts. After that, the “worst” post-effort is
deleted.
Note Pre- and post-efforts must happen on the same day, with the same calibration.
The next day — or after a recalibration — tests become available for review only;
you can no longer add efforts to them.
