3. Close the transducer stopcock to the patient.
4. Open the venting stopcock to air (atmosphere). The monitor displays a flat
waveform and a static IBP condition for the systolic (S) value.
5. Click on
Zero
.
6. Verify that the zero has been established. If zeroing failed, repeat steps 2 to 6.
If zeroing is successful, continue.
7. If applicable, select
Cal. Factor
and click the knob.
8. Dial in the calibration factor and click the knob.
9. If you are monitoring two invasive blood pressures, repeat these steps for the
second pressure parameter.
Zero and Calibration Check Troubleshooting
NOTE: The monitor displays an error message ( IBP1 Cannot Zero or IBP2 Cannot
Zero ) when zeroing fails. Call your Biomed or replace the transducer if zeroing fails
after two attempts. If the monitor rejects the calibration factor that you selected, change
the transducer or call your Biomed. The transducer needs to be calibrated.
Screen Message Possible Cause Suggested Action
IBP Cannot Zero,
IBP Zero Time-out • The transducer offset is outside
the zero balance range of +/-
190 mmHg
• The signal is too noisy.
• The waveform is non static
(more than 3 mmHg variation in
3 seconds).
• The monitor was unable to zero
the transducer within 10
seconds.
• Verify the pressure cable connection
to the monitor.
• Keep all tubing motionless.
• Check the stopcock and verify that the
system is open to air completely.
• Repeat the zeroing procedure.
• Replace the transducer if faulty.
IBP Invalid Cal • The calibration factor is outside
the range of 80 to 120
(inclusive).
• Replace the transducer if calibration
fails after two attempts.
• Call your Biomed to calibrate the
transducer with a mercury manometer
if calibration fails repeatedly.
• Check the pressure cable for damage.
Note that instead of “IBP” the messages show the selected pressure label
(e.g., “
ART Cannot Zero ”).
