How Long is Dexcom Transmitter Good For?

Dexcom transmitters are a popular choice for those living with diabetes, as they provide real-time glucose readings for up to 10 days. However, it is important to understand the longevity of your Dexcom transmitter to ensure accurate readings and to maintain your quality of life. This article will explain how long your Dexcom transmitter is good for and how to ensure it lasts as long as possible.

What Is a Dexcom Transmitter?

A Dexcom transmitter is a device that attaches to a continuous glucose monitor (CGM) and collects glucose data from the sensor. It then sends the data wirelessly to a compatible receiver, such as a smartphone, so that you can track your glucose levels in real time. The transmitter is a long-lasting device, but its lifespan can vary depending on how it is used and maintained.

The Dexcom transmitter is an important part of the CGM system because it collects glucose data from the sensor and sends it to the receiver. Without the transmitter, the user would not be able to get real-time glucose readings. It is also important to note that the transmitter must be replaced when it reaches the end of its life.

The lifespan of a Dexcom transmitter varies depending on how it is used and maintained. Generally, the transmitter will last for up to 10 days before needing to be replaced. However, it is important to note that if the transmitter is not properly maintained, it may not last as long as 10 days.

In order to ensure that your Dexcom transmitter lasts as long as possible, it is important to take proper care of it. This includes regularly cleaning the transmitter with a damp cloth and avoiding any water exposure. It is also important to keep the transmitter away from extreme temperatures, such as hot car interiors or freezing temperatures.

How to Replace a Dexcom Transmitter

Once your Dexcom transmitter reaches the end of its life, it will need to be replaced. Replacing the transmitter is a simple process, but it is important to follow the instructions carefully to ensure the transmitter is installed correctly.

The first step is to remove the old transmitter from the receiver. To do this, press and hold the transmitter’s power button for five seconds until it turns off. Once the transmitter is off, you can remove it from the receiver.

How to Activate a New Dexcom Transmitter

Once the old transmitter has been removed, the new one can be activated. To activate the new transmitter, insert the battery into the transmitter and press the power button. The transmitter will then start the activation process.

Once the transmitter is activated, it can be connected to the receiver. To do this, press and hold the transmitter’s power button for five seconds until it turns on. The receiver should recognize the transmitter and the connection will be established.

Conclusion

Dexcom transmitters are a vital part of the CGM system, providing real-time glucose readings for up to 10 days. However, it is important to understand the longevity of your Dexcom transmitter and take proper care of it to ensure accurate readings and to maintain your quality of life. If the transmitter needs to be replaced, it is important to follow the instructions carefully to ensure the transmitter is installed correctly.
