Have you or a loved one taken advantage of the recent Federal Government CGM subsidy initiative? A CGM has the potential to change the lives of young people with type 1 diabetes and their carers, but it’s important to know how to correctly use it.

It has come to the attention of Diabetes WA that there may be confusion amongst CGM users about how often to change the transmitters on their CGM. Here’s the facts;

 

Sensors

The glucose sensor is the tiny electrode that sits under your skin and measures your glucose levels.

Timespan: Each glucose sensor can be worn for around one week, depending on the product manufacturer (see table below). Glucose sensors have a 6-month expiration date from the time they are manufactured. The expiration date is on the outside of the glucose sensor box and on each individual glucose sensor package.

 

Transmitter

The transmitter is the small, lightweight device that attaches to the glucose sensor, gathers your glucose data, and sends it wirelessly to the larger monitoring and display device.

Timespan: If used continuously, the transmitter has a life of approximately 3-12 months, depending on the product manufacturer (see table below).

 

Know your Device

The below information specifies the usage timeframes and the compatible sensors and transmitters for each CGM device.  The lifespan field shows how long each sensor and transmitter should be used for, this is not to say that the sensor or transmitter will cease to function after these timeframes, it is the recommended timeframes supplied by the manufacturer.
