With a Freestyle Libre Sensor you can continuously measure your blood sugar for 14 days. Attaching the sensor using the sensor applicator is well described in the instructions for use. When attaching the sensor, a small, 5mm long, flexible cannula is placed under the skin (usually painless). The sensor is worn on the back of the upper arm and continuously measures your glucose levels. It is waterproof and can be worn while bathing, showering or swimming. If you set up additional optional alarms, you will be warned in good time about hypoglycemia, for example, and can therefore feel even safer - day and night.
