Sensitivity

Note:
Excessively high setting of the maneuver sensitivity can affect the accuracy of timing for P100 determination.

Start / Stop

Note:
If the Start key is activated during a mandatory inspiratory breath the maneuver will not commence until the ventilator
cycles into exhalation and the minimum expiratory time of 150 msec has elapsed.
Alarms
All currently available alarms shall be active during the MIP / P
Low PEEP.
To Perform a MIP / P100 Maneuver:
The MIP / P100 maneuver allows the measurement of the Maximum Inspiratory Pressure (MIP) achieved by the patient
during an expiratory hold maneuver. The ventilator can also measure the P100 value which is the maximum inspiratory
pressure achieved in the first 100 milliseconds of the maneuver.
From the Maneuvers Screen select MIP P100
The MIP maneuver screen allows the operator to set:
Duration – This is the time period that ventilation is suspended to conduct the maneuver. Once the Start button is
depressed normal ventilation will be suspended until the Duration time period has elapsed or the operator presses the
Stop button.
Sensitivity – This sets the sensitivity threshold that the ventilator uses to begin the timer for the P100 maneuver. The
default position is 3 cmH
effort.
Chapter 4: Monitors, Displays and Maneuvers
The maneuver sensitivity establishes the level below PEEP that the airway pressure must
drop, which determines the onset of a patient effort. This allows the clinician to set the
maneuver appropriate to patient ability.
Range: 0.1 to 5.0 cmH
Resolution: 0.1 cmH

Default: 3.0 cmH
The maneuver begins when the START key is actuated. The maneuver will be immediately
terminated should the operator activate the STOP key and normal ventilation will resume.
