5 Insert or Remove Your Sensor
Purpose
To insert, remove, or replace a small, thin, plastic sensor under your skin so that your
FreeStyle Navigator system can continuously monitor your glucose level.
Start
Do this procedure:
• The first time you use your FreeStyle Navigator system.
• Every 5 days after that.
• Replace your sensor sooner than 5 days when:
– There is any redness, pain, tenderness, or swelling at the insertion site.
– An error code displays on your receiver indicating a sensor problem.
• When replacing batteries.
Materials
Gather these materials before you begin:
• Soap and water.
• Alcohol prep pads.
• A sensor delivery unit in its UNOPENED package.
• Your transmitter.
• Your receiver.
Helpful Information
Important: Keep the following in mind when inserting your sensor.
• You will not have continuous monitoring data until you have successfully completed the first
calibration (at least for the first ten hours after sensor insertion).
• You may not be able to calibrate the system if your glucose levels are changing rapidly. For example,
during a meal or exercise, your glucose levels may vary rapidly. Try to time your insertion so that
your calibration times do not coincide with your regular meal or exercise activities.
Note: You should keep your sensor inserted for 5 days. See the exceptions listed above under Start.
• The system will ask you to perform 4 calibrations at approximately -10, 12, 24 and 72 hours after
inserting a new sensor (See Section 7).
• You MUST change your sensor every 5 days, to reduce the chance of infection. The system
automatically terminates a sensor session after 5 days. Do NOT leave the sensor inserted for more
than 5 days.
• Taking action at the first sign of irritation or discomfort will keep small issues from turning into
larger or ongoing ones.
• You may not be able to perform the calibration after you eat until your glucose levels stabilize.
• See Appendix A: Site Maintenance for additional helpful suggestions.
• Before inserting a new sensor make sure that there are no low battery messages displayed on the
receiver. This will help avoid data loss after the insertion if the batteries are running low.
Interferents: In vitro and in vivo testing suggest that usual pharmacologic levels of ascorbic acid have
no effect on the function of the system but salicylic acid has minimal effect. In vitro testing suggests
that normal physiologic levels of uric acid, lipids, and bilirubin do not affect system function. The
impact of oral hypoglycemic agents and other potential interfering substances has not been studied.
