During a trend test, the following values are reported to the user every time a breath
occurs:
Test Parameter – This is the parameter that was chosen for running this test. This
value does not change during the test.
Current Value – This is the current value of the chosen test parameter. Every time a
breath occurs, this is updated and compared against the initial value of the test parameter.
Starting Value – Shows the initial value for the test parameter. This value does not
change during the test.
% Difference – This value is calculated each time a breath occurs. If it is greater than
the % limit, an incident is reported.
% Limit – This is the value entered before starting the test. It does not change during the
test.
# of Tests – Incremented each time a breath is detected.
# of Incidents – The number of incidents is incremented each time the percent
difference exceeds the percent limit.
Elapsed Time – This value is updated continuously. It keeps track of the length of time
the current trend test has been run.
