Pressure Monitoring
A Perfusion Screen can be configured to monitor up to 8 pressure locations through
the use of 4 modules with each module having 2 channels. Pressure transducers
used with System 1 must meet the ANSI/AAMI BP22:1994 standard for physiologic
pressure transducers. Independent of the transducer, the system will perform over a
range of -30 to 300 mmHg with an accuracy of +/- 10 mmHg.
CAUTION:
The accuracy of the pressure information is dependent on the
specification of the pressure transducer. Always ensure that the pressure
transducers used are appropriately specified for the application.
CAUTION:
Although the System 1 is capable of displaying values from the
pressure transducer between –250 mmHg and +900 mmHg, no claim of
accuracy beyond the range of -30 to 300 mmHg has been determined.
For values below -250 mmHg or in the condition of a disconnected transducer, the
pressure icon on the CCM will display “– – –”. For values above +900 mmHg, the
icon will display “999”.
In the event of overrange/underrange readings or pressure system malfunction,
physiological alerts or alarms are cleared automatically. If a safety connection from
a pressure event had paused or stopped a pump, that pump can then resume or be
restarted (if no other pause or stop responses are in effect). If the pressure reading
returns into range between -250 mmHg and +900 mmHg, inclusive, the physiological
alerts or alarms will reoccur as appropriate.
The pressure system has only been tested with pressure transducers provided by
Terumo Cardiovascular Systems.
Pressure data can be used as a servo setpoint to regulate roller and centrifugal pump
speeds. See the Roller Pumps and Centrifugal Control Unit chapters, Servo
mode
sections for instructions on using pressure data as a servo setpoint.
When changing disposable transducers during use, disconnect the pressure
transducer cable from the module.
WARNING: Pressure transducer cables without transducers attached must be
disconnected from the system. Cables without transducers act as antennas and
may stop the pump due to electromagnetic interference.
WARNING:
Use only the specified temperature probes and pressure
transducers to ensure that the temperature and pressure monitoring function
properly.
Label and Connect Pressure System
1. Mark both ends of pressure cable with identical codes, using the correct size of
marker from the accessories kit.
2. Connect the pressure cable to the correct channel on the pressure module.
Properly align the pressure cable with the module receptacle.
• Each channel is assigned separately during configuration. Each pressure cable
must be attached to the proper channel for the pressure reading to display in the
correct location on the Perfusion Screen.
3. Insert pressure module into base receptacle as close as possible to the location
where the transducer will be used. Arrange cables to minimize exposure to spills.
