To combine the assisted mode with the control mode, the clinician must adjust the trigger
sensitivity (Tr. I) at a value that suits the patient.
If during the expiratory phase, the patient generates a spontaneous breath that activates
the trigger, the ventilator will synchronise its activity to the patient's spontaneous breath,
recalculating the I:E cycle times starting from that event and displaying them on the
ventilator screen.
This way the ventilator provides a minimum number of breaths as indicated on the RATE
display of the integrated screen.
If the patient's spontaneous breathing respiratory rate is greater (than the respiratory rate
set on the ventilator) the machine will increase the number of breaths per minute (with
regard to the number set in the control panel) and displays the value on the integrated
monitor.
