What is a CGM Transmitter?

A CGM transmitter is key in a continuous glucose monitoring (CGM) setup. It helps people with diabetes watch their glucose levels continuously. This device sends the glucose level data from the sensor to a receiver or a smartphone/smartwatch.

Definition and CGM transmitter function

This device is small and light, connecting to the glucose sensor under the skin. The sensor and transmitter work together to pick up glucose readings and send this information to a receiver or smart device. Users can see their glucose levels all the time, helping them make wise choices about their health.

CGM transmitters are very advanced and use wireless communication for smooth data sharing. For example, the Dexcom G6 transmitter can handle being wet and is fine for swimming. This feature offers constant glucose checks, which are proven to aid in diabetes care, lessen hypoglycemia risks, and keep glucose levels in check.

Components of a CGM System

A typical CGM system has these three main parts:

Glucose sensor: It’s small, goes under the skin, and checks glucose levels in the fluid around cells.
Transmitter: This device links to the sensor and sends the glucose information to another gadget.
Receiver or smart device: It shows the data sent by the transmitter, helping users keep an eye on their glucose levels in real time.

In the Dexcom G6 system, the transmitter can be used again. However, some may have one-use transmitters that come with the sensor. This setup provides options depending on the model.

How CGM Transmitters Work

CGM transmitters are key in the continuous

Data Transmission from Sensor to Receiver

The sensor in a CGM system looks at glucose in fluid under the skin, not in the blood. The smart transmitter saves data when the device is out of range, sending it to an app later. After putting the transmitter back on the sensor, it’s around a 10-minute wait for glucose readings to show in the app6.

You usually need to change the sensor every 7 to 14 days. The sensor lifespan varies, with some special sensors lasting up to 3 months or even longer7. A transmitter can last for 3 months to over a year, depending on the device.

Compared to traditional blood glucose checks, CGM gives 288 readings daily, which is much more detailed5. This frequent check-up lets users keep close tabs on glucose levels. The Eversense E3 Continuous Glucose Monitoring system can monitor for up to 180 days for adults with diabetes6.

Wireless Communication Technology

CGM transmitters use advanced wireless tech to transmit glucose level data safely and steadily and are often waterproof up to a meter for half an hour. They’re waterproof up to a meter for half an hour so you can swim or shower without worry. But, don’t forget to take it off before an MRI, although the sensor can stay on.

Types of CGM Transmitters

Continuous Glucose Monitoring (CGM) systems are changing how we manage diabetes. They give real-time info and trends on sugar levels. A key part of these systems is the CGM transmitter. It sends glucose data from the sensor to the receiver or a smart device. Thinking about what type of transmitter fits your lifestyle is crucial when picking a CGM system.

Reusable Transmitters

Reusable CGM transmitters can be used for months to a year. They work with a disposable sensor placed under the skin on the belly or upper arm. After the sensor is put in, the transmitter is connected. This allows for steady glucose level reporting. The Diabetes Consumer Guide states that 60% of CGM systems send data to smart devices. Forty percent have long-range transmitters.

Using reusable transmitters can save money over time. The main cost is upfront. But, because the same transmitter can work with different sensors, it saves money in the long run. It’s good to remember that some reusable transmitters need to be charged regularly to work, which is something to think about.

Disposable Transmitters

Disposable CGM transmitters come with the sensor and are thrown away after 7 to 14 days. This depends on the model. They make managing diabetes simpler as there is no hassle of recharging or reattaching them. For example, the FreeStyle Libre flash CGM system has a disposable transmitter with an accuracy rate of 9.7%.

Choosing disposable transmitters means more spending because they need to be replaced often. But for people who don’t want to deal with various parts, they offer an easy option. Plus, some disposable types, like the Dexcom G6, don’t need calibration or finger pricks before making treatment choices.
