Chapter 5 - Cgm Calibration - Dexcom g4 platinum Quick Start Manual

ANIMAS® VIBE™ SYSTEM

cHAPtER 5 - cGm cAlIBRAtION

In order for your CGM to work properly, you will be prompted to calibrate your CGM with fingerstick BG
test results at various times during a CGM session. More specifically, you will need to be prepared to
take a fingerstick test(s) with your commercially-available BG meter, and enter the BG results into your
pump within 5 minutes of being prompted. The purpose of calibration is to correlate Sensor readings
to the reference BG meter to maintain Sensor performance.
These are the required times for calibration:
• Startup Calibration – at the end of the 2-hour CGM startup period.
• Calibration Update – at least once every 12 hours during a CGM session.
• Recalibration – is required if one of the fingerstick BG values entered for Startup Calibration or
Calibration Update is not accepted by the pump.
NOTE: You may see a few second delay in screen display immediately after entering a CGM calibration
value. This is normal as the calibration value is processed.

CONTRAINDICATION: Taking acetaminophen-containing medications while wearing the
Sensor may falsely raise your Sensor glucose readings. The level of inaccuracy depends on the
amount of acetaminophen active in your body.

WARNING:
• CALIBRATE your Sensor with a BG value from a BG meter at least once every 12 hours. Periodic
BG values from a BG meter adjust the Sensor so that it more accurately reflects your body's
health status. The accuracy of your Sensor glucose readings may be compromised unless you
calibrate at least once every 12 hours. Calibrating more than once every 12 hours is okay and
will not affect the accuracy of your Sensor glucose readings.
• DO NOT use a BG value for CGM calibration unless it is from a fingerstick test taken with a
BG meter within the last 5 minutes, and is within 40 – 400 mg/dL. Failure to follow these
instructions can result in inaccurate Sensor glucose readings.
• When using your BG meter to obtain CGM calibration values, it is important to follow these
instructions to ensure the accuracy of the BG values used for CGM calibration.
Always use a fingerstick test.
˚
˚ DO NOT use alternative sampling sites (e.g., palm or forearm).
˚ Always use the same BG meter for calibration for each CGM session.
DO NOT switch your BG meter in the middle of a CGM session.
˚
˚ Follow your BG meter instructions for BG testing.
˚ Follow proper BG testing techniques to ensure accurate calibration values and CGM
performance.
