What is a glucose sensor?
The glucose sensor is a tiny electrode worn for up to 3 days. Following a 2-hour initialization period, the glucose sensor measures glucose levels in the interstitial fluid which is where cells get oxygen and nutrients, including glucose. The glucose sensor is easily inserted by patients, caregivers or healthcare providers into the skin (subcutaneous tissue) using the Sen-serterĀ® automatic insertion device. Like many types of infusion sets, a needle is used to introduce the glucose sensor but the needle is then removed leaving a tiny flexible electrode just under the skin. The glucose sensor is then connected to the transmitter so the readings from the glucose sensor can be transmitted to your insulin pump.
