calibrating sensors chapter 5 5-1 PB
This chapter explains how to calibrate sensors prior to clinical use.
Setting up and starting calibration
For the calibration procedure, you need the following: the Terumo Cardiovascular
Systems (Terumo) CDI System 550 Monitor, the Terumo CDI Model 540 Calibrator
with the Gas A and Gas B bottles installed, and the sensor(s) you’re calibrating (arte-
rial and/or venous sensors).
Before calibration, make sure the calibrator is set up as described in the section
“Preparing the calibrator” in Chapter 3. (First insert the gas bottles into the calibrator,
then either hang the calibrator on the monitor pole clamp or place it on a flat surface
near the monitor.)
Note:
The calibration procedure is not available if running on backup battery power.
Warning
• Failure to perform the gas calibration on the shunt sensor before use
may result in compromised system performance that does not meet
the System Accuracy Limits found in Appendix B.
Warning
• Failure to complete calibration as described in Chapter 7, Completing
Calibration of the CDI System 550 Measurements, may result in
compromised system performance that does not meet the System
Accuracy Limits found in Appendix B.
After the calibrator has been set up properly, and has been connected to the
monitor, follow these steps to calibrate the sensors:
1 Put the monitor into calibrate mode.
To do this, first press the system mode select key, use the and keys to high-
light the “calibrate” label (at the bottom of the screen), then press √.
The following screen appears when you enter calibrate mode:
calibrate
standby calibration setup
operate
Arterial sensor
Please verify the K+ calibration value
located on the sensor package.
Adjust the value if necessary, then press
the OK ( ) key to continue.
