O que é a Monitorização Contínua da Glicose (CGM)?

Continuous glucose monitoring provides a more complete picture of a patient’s glucose levels, compared to what you can obtain from a blood glucose meter (BGM). More frequent access to glucose insights leads to more effective diabetes management, for you and your patients.1,2

The Difference is in the Data

Dexcom CGM difference

Some people with diabetes may struggle to understand how diet and exercise play a role in their treatment, or how to effectively titrate insulin accordingly.


But with continuous glucose readings from Dexcom G6, users can see a complete view of their glucose levels in real time, including historic and current glucose values and rate of glucose change, without requiring action from the user providing users with actionable information, over and above a single BGM reading.

Continuous Insight, Day and Night  

Dexcom G6 helps minimise the guesswork derived from making diabetes treatment decisions based on a BGM reading alone and requires zero fingersticks* or scanning to access glucose data, helping to empower patients to self-manage their diabetes.

Primary CGM Components

The Dexcom G6 CGM System consists of four main components: 



Simplifica a aplicação do sensor, bastando premir um botão. O doente pode aplicar o sensor sozinho, seguindo as instruções de utilização. 



Monitoriza os níveis de glicose intersticiais através de um pequeno cabo introduzido mesmo por baixo da pele, que envia um sinal para o transmissor (vida útil de 10 dias). 



Fixado na parte superior do sensor; envia dados sem fios para o dispositivo de visualização do utilizador (vida útil de 3 meses). 

Dispositivo de visualização

Dispositivo de visualização

Permite que os doentes visualizem os seus dados e tendências de glicose em tempo real. O Dexcom G6 também permite que os doentes recebam um conjunto de alertas, incluindo um alerta preditivo de «Baixa urgente para breve», um alerta «Baixa urgente» e outras notificações no seu dispositivo de visualização, que podem avisar quanto a níveis altos ou baixos de glicose. 

The Benefits of CGM for Insulin-Using Patients  

Proven outcomes support your patients' progress compared with conventional blood glucose management (BGM). 

Hipoglicemia reduzida

Hipoglicemia reduzida

O alerta preditivo «Baixa urgente em breve» oferecido pelo Dexcom G6 está associado a uma redução da hipoglicemia, sem o risco correspondente de  hiperglicemia.‡,1 

Redução da HbA1c

Redução da HbA1c

A utilização do Dexcom CGM reduz a HbA1c independentemente da utilização de múltiplas injeções diárias (MDI) ou da bomba de insulina.

Maior tempo no intervalo recomendado (TIR)

Maior tempo no intervalo recomendado (TIR)

Regra geral, os doentes que utilizam o Dexcom CGM passam mais tempo no intervalo glicémico recomendado em comparação com os utilizadores de medidores de glicemia.3,4 

Melhoria da qualidade de vida

A utilização do Dexcom G6 melhora a qualidade de vida e o bem-estar.5,6 

Long-Term CGM use Supports Long-Term Benefits and Outcomes

A three-year, real-world clinical trial—the longest CGM outcome study to date—reiterates the clinical impact of using rt-CGM Systems like Dexcom CGM. Study participants with type 1 diabetes (T1D) using a Dexcom rt-CGM System showed significantly reduced HbA1c levels, increased time in range (70-180 mg/dL), and decreased time below range (<55 mg/dL), independent of the insulin delivery method.2

Rt-CGM supports improved diabetes management for your patients in a way that is both accessible and sustainable. Whether your patients are sitting down for a meal, leading a presentation, or getting ready for bed, they can feel more confident in their daily diabetes treatment decisions that help shape the rest of their lives.

‡This predictive alert can be triggered with impending hypoglycaemia (glucose of 55 mg/DL or below is predicted to occur within the next 20 minutes). 

§ Register for Dexcom CLARITY at clarity.dexcom.com/professional/registration. 

|| An internet connection is required for patients to send their glucose data to Dexcom CLARITY via a compatible smart device: dexcom.com/compatibility 

¶ Healthcare Professionals will only be able to view a patient’s glucose data if the patient elects to share it with them through Dexcom CLARITY.
