Monitoring Invasive Pressure
Measurements from an MMS extension connected to an X2 are not available when the X2 is running
on its own battery power. They are only available when the X2 is powered by external power: when
connected to a host monitor, to the external power supply (M8023A) or to the Battery Extension
Do not use a monitor with an M1006A pressure module as an additional monitor for your patient. This
may cause interference on the respiration or invasive pressure measurements.
You can measure pressure using an X1 or X2 Multi-Measurement Module (MMS), one of the MMS
extensions or the pressure plug-in module - labeled as PRESS. With the plug-in module you may see a
wave channel before the pressure cable is plugged in - with the MMS this will not be the case.
Setting up the Pressure Measurement
Plug in the pressure cable.
Prepare the flush solution.
Flush the system to exhaust all air from the tubing. Ensure that the transducer and stopcocks are
free of air bubbles.
If air bubbles appear in the tubing system, flush the system with the infusion solution again. Air
bubbles may lead to a wrong pressure reading.
Connect the pressure line to the patient catheter.
If you are using an infusion pressure cuff with the pressure line, attach the pressure cuff to the
fluid to be infused. Inflate it according to your standard hospital procedure, then start the infusion.
Position the transducer so that it is level with the heart, approximately at the level of the
