CHAPTER 6: INSERTING A SENSOR AND
STARTING A SENSOR SESSION
You need a sensor, a transmitter, a receiver and a receiver shield to
use the Dexcom G4 PLATINUM Professional Continuous Glucose
Monitoring System. You also need a blood glucose meter and test strips
for calibration. The blood glucose meter and test strips are not provided
in the Dexcom G4 PLATINUM Professional System. The sensor
continuously measures and displays the sensor glucose readings for up
to 7 days when in real-time mode. The following sections will show you
how to insert the sensor and start a new continuous glucose monitoring
session both in real-time and blinded modes.
WARNING
Sensors may fracture on rare occasions. If a sensor
breaks and no portion of it is visible above the skin, do
not attempt to remove it. Seek professional medical help
