5.
If the ZERO menu is not displayed, from the Main Menu press
INVASIVE PRESSURE
, 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.
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.
