Directions for Use Monitoring 29
5. If the ZERO menu is not displayed, from the Main Menu press INVASIVE
PRESSURE, and then ZERO P1 (or ZERO P2). The word ZEROING appears in the
numerics window during zeroing.
If you want to cancel the zeroing process, press CANCEL.
6. Wait for a brief tone to sound and the word ZEROED to appear in the blood pressure
numerics window.
7. Close the transducer's stopcock. The monitor displays the pressure scale and
numerics.
8. If the transducer will not zero, the monitor displays the words ZERO REJECTED in the
numerics window. Press CANCEL and try zeroing again beginning at step 4. The
monitor does not display numerics or scales until an acceptable zero reference is
established.
You can rezero an IBP transducer at any time after you again open the transducer
stopcock to atmospheric air. If the transducer has already produced pressure
readings, rezeroing provides a new zero reference for the monitor.
If the zero value is not accepted, the monitor continues to use the previous zero
reference and displays numerics and waveforms based on that value.
If the transducer still does not zero, try another transducer or another cable.
9. To set up the IBP display, from the Main Menu press INVASIVE PRESSSURE to
display the first IBP menu:
WARNING If you press ZERO after an invasive pressure channel has been
successfully zeroed and the channel is currently monitoring a pressure waveform,
the message ZERO REJECTED will display in the IBP numerics window. This
message continues to display in place of the valid invasive pressure numerics
until you press Home, INVASIVE PRESSURE, and then CANCEL in the IBP menu.
If an IBP alarm occurs while ZERO REJECTED is displayed in place of IBP
numerics, the IBP numerics will not flash to indicate invasive pressure is in alarm.
