Guardian 4 - Precautions

- 3 -
If bleeding occurs, do the following:
1. Apply steady pressure, using sterile gauze or a clean cloth
placed on top of the sensor, for up to three minutes. The use of
unsterile gauze may cause site infection.
2. If bleeding stops, connect the transmitter (or recorder) to the
sensor.
If bleeding does not stop, do not connect the transmitter to the
sensor because blood may get into the transmitter connector,
and may damage the device.
If bleeding continues, causes excessive
pain or discomfort, or is significantly visible
in the plastic base of the sensor, do the
following:
Plastic base
1. Remove the sensor and continue to apply

a healthcare professional.
3. Insert a new sensor in a different location.

Precautions
Wash hands with soap and water before inserting the Guardian 4
sensor to help prevent site infection.
Do not insert the sensor through tape. Inserting the sensor through
tape may cause improper sensor insertion and function.
Only use alcohol to prepare the insertion site. Using alcohol to
prepare the insertion site makes sure that residue is not left on the
skin.
Rotate the sensor insertion site so that sites do not become
overused.
Do not clean, resterilize, or try to extract the needle from the
needle housing. An accidental needlestick or puncture may occur.
Do not reuse sensors. Reuse of a sensor may cause damage to
the sensor surface and lead to inaccurate glucose values, site
irritation, or infection.
