What is a glucose monitoring device?
Glucose monitoring devices are applied to your body and are used to measure and track glucose levels within the body. Your device may be a continuous glucose monitor (Dexcom and Medtronic are examples) or a flash glucose monitoring device, such as Freestyle Libre. If you are unsure about your device and where to access safety recommendations, please refer to the user manual provided by the manufacturer or visit their website.
What should I do if I wear a glucose monitoring device and need to be admitted to hospital?
Continuous and flash glucose monitors are not approved for use while in hospital. Medications given during your stay can cause the device to be less accurate and give false readings. While in hospital, your care team will monitor your glucose levels using a blood glucose meter. Insulin dosing is based only on the findings of the hospital blood glucose meter. If you would like to continue using your device while in hospital, please be aware all medical staff will not be able to read, use, or make decisions based on these findings.
What if I require an X-ray, CT scan, MRI, or high-frequency electrical heat (diathermy) treatments?
Your device must be removed prior to procedures involving high electromagnetic fields (such as an X-ray, CT scan, MRI, diathermyl, etc.). This is detailed in the manufacturer’s guidelines for your device. Exposure to electromagnetic fields can damage the sensor and may cause the device to give incorrect readings following the procedure. It is recommended that you remove all components of the monitoring system (sensor, transmitter, receiver/smart device) prior to arriving at the hospital. While in hospital, your care team will monitor your blood glucose levels with specialized equipment.
