PRESSURE LIMITS
PIP Limit (Respiratory Tract Pressure)
This limit can only be used with a separate measuring lead (proximal lead). The control panel displays
the current patient respiratory tract pressure in graphics and numbers. This allows ventilation patterns
to easily be recognised.
The display is automatically gauged based on the PIP alarm settings. If the pressure exceeds the de-
fined limit the main valve shuts off and an alarm notification appears on the display. The valve will only
be reactivated once the pressure has fallen to 40% of the limit. The audible alarm is automatically reset
once the main valve is cleared.
In graphics this PIP limit is displayed as a broken line!
PP Limit (Pause Pressure)
The PP alarm is activated as soon as the MONSOON is in automatic mode and the
“Start / stop”
key
has been pressed.
The pause pressure corresponds to the pressure inside the Jet lead and is measured a few millisec-
onds prior to engaging the main valve. The current patient respiratory tract pressure is indicated nu-
merically on the control panel. This method allows the residual pressure inside the lead to be meas-
ured. If the value exceeds the limit the valve can only be activated once the pressure inside the lead
falls to 20% of the limit. The audible alarm is automatically reset once the main valve is cleared.
Superimposed Pressure Limit (Superimposed Ventilation)
The SIPL limit works similar to the PIP limit, but will only disable the Jet valve 1 while the value exceeds
the limit, without triggering an alarm. This method allows the use of superimposed Jet ventilation.
Setting the SIPL limit below 10mbar will disable this limit.
The SIPL limit must be set to below the PP limit or ventilation will be interrupted due
to responding to the PP limit.
The SIPL is further automatically limited by the PIP.
The following formula applies: SIPLmax = PIP Ist - 5mbar
In graphics the PIP limit is displayed as a broken line!
