The start trigger is defined as the start of the
inspiration phase.
The stop trigger is defined as the end of the inspiration phase
and start of the expiration phase.
Expiration continues until the next start trigger appears.
10 Measuring Respiratory Coefficients
10.1 General To be able to measure respiratory coefficients the
FlowAnalyzer
TM
has to be able to pick out a respiratory
cycle from the pressure and/or flow curves. The triggers are
controlling this.
It is therefore essential that the start and stop triggers are
correctly defined, as they have a significant effect on the
resulting measurements.
The set triggers are used to trigger a respiratory cycle (> 7.14
Setting the Trigger ).
It is therefore very important that the triggers are set correctly
before starting to measure the respiratory coefficients.
