Sensitivity
Use the Sensitivity control to establish the threshold level to allow the patient to flow trigger Assist
and Patient breaths.
A flow trigger occurs when:
• The sensitivity is set to any value from 1 to 9,
• And the ventilator is in exhalation phase,
• And the minimum exhalation time has expired,
• And the flow is greater than or equal to the Sensitivity setting.
The LEAK measurement displayed in the RT XDCR DATA menu can be used to help select an
appropriate sensitivity value. Typically, the sensitivity value is set higher than the displayed LEAK
measurement. For instance, if the LEAK measurement were up to 2.53, a minimum sensitivity of
three (3) would be appropriate.
Backup pressure triggers are enabled when the setting is any value other than a dash “-”.
A backup pressure trigger occurs when:
• The sensitivity is set to any value from 1 to 9,
• And the ventilator is in exhalation phase,
• And the minimum exhalation time has expired,
• And the airway pressure drops below -3 cmH
