Dexcom 5G Mobile CGM work
Can the monitoring device Dexcom G5 Mobile Continuous Glucose Monitoring System (Dexcom G5 Mobile CGM) revolutionize glucose monitoring and set the standard in the near future? Dexcom G5 CGM is the first real-time glucose trends detecting device for adults and children 2 years and older with diabetes. The aim is to detect hyperglycemia (glucose levels too high) and hypoglycemia (glucose levels too low) in real-time with alerts and to help patients to make treatment decisions for example, administer insulin or carbohydrates. It will also facilitate long-time therapy for patients by helping them to determine the patterns in glucose levels. (United States, Food and Drug Administration, FDA 2017.) Dexcom G5 CGM needs prescription and is intended for a single patient use. It consists of a small flexible metal wire sensor (worn subcutaneously for up to 7 days), a transmitter (externally-worn) and a dedicated receiver and/or compatible mobile device. The sensor will respond to the amount of sugar by generating a small electrical signal, which the transmitter will then collect as a glucose value. The transmitter will send the collected values and trends to the receiver every 5 minutes via Bluetooth connection. Before that user must download the application from Android Market or from iTunes App Store and create Dexcom account. Then connect the receiver/mobile device with the transmitter and insert the sensor under the skin. After that user can start receive glucose information. (Dexcom 2017.)

It is important to know that the transmitter and sensor must be removed before MRI, CT scan or diathermy treatment and if medications with acetaminophen is in use while wearing the Dexcom G5, glucose readings may falsely raise (Dexcom 2017).
For proper user safety, the equipment must always be in good condition and the system must be calibrated every 12 hours by using a fingertip blood sample. The system will start show glucose values only after 2 hours from startup. If the system does not show glucose values, user must always take fingertip blood sample and make the treatment decision according to that value. User must also never ignore high or low glucose symptoms despite that the system shows normal glucose values. The system has not been tested with pregnant women and with persons in dialysis so the glucose readings may be inaccurate. (Dexcom 2017.)
