prevents further increase in pressure. If this happens in a few breathing cycles, the alarm for
not delivering the user's adjusted volume will be activated (see the alarms chapter).
The flow Pttern sets by the user. Two square and decelerating (Decel.) flow patterns are
selectable in this ventilator.
The time which neither air is delivered to the patient nor exhaled from the patient's lung
through the airway defin as a Pause. This parameter is adjustable as a percentage of
inspiratory time between 0 and 75%.
Note:
While Vt, Rate, Pause and Ti parameters are changed by the user, Flow and Pause time will
be displayed on the screen. It should be noted that if Compliance Compensation and Leak
Compensation are desabled, the deliverd flow may be different from the flow displayed on
this menue.
Note:
During inhalation, if the airway pressure for any reason (such as the patient's cough) exceeds
the value specified for it, the exhalation valve opens and prevents further increase in pressure.
Adjustable parameters in V-SIMV mode are:

Inspiratory time
The method of detecting the patient's respiratory effort (flow or pressure).
Threshold of detecting patient respiratory effort based on flow or pressure
Percentage of peak inspiratory flow in spontaneous breath necessary to
inhalation
terminate and initiate exhalation.
Time required for inspiratory pressure to rise to set pressure
Percentage of inhalation time after which the current volume is delivered,
respiration remains in the inhalation and then exhalation begins. During this
period, no volume is transferred to the patient.
the pattern of applied flow to the patient
If the patient tries to breathe during inhalation, the device responds to this
request by switching on the pressure control
