Can Dexcom's CGM system be used with insulin pumps?
A7: Yes, Dexcom's CGM systems can be integrated with compatible insulin pumps. The Dexcom G6 CGM system, for example, is compatible with various insulin pumps, allowing users to view their glucose data on the insulin pump's display. This integration helps users make informed decisions about insulin dosing and timing. Dexcom provides comprehensive guides and resources to help users set up the integration properly.
How does Dexcom's CGM system handle exercise and physical activities?
A8: Dexcom's CGM systems are well-suited for individuals engaging in exercise and physical activities. The devices are designed to accurately measure glucose levels during movement and offer trend information to help users understand how exercise affects their glucose. It is important to note that strenuous activities can occasionally interfere with the sensor's stability or accuracy. Therefore, users should closely monitor their glucose and consider taking additional precautions, such as securing the sensor or using overlays, if necessary.
Can I trust the alarms and alerts provided by Dexcom's CGM system?
A3: Dexcom's CGM systems are designed to provide reliable and timely alarms and alerts to users. These alerts notify individuals when their glucose levels are too high or too low, helping to prevent potential hypoglycemic or hyperglycemic events. Dexcom's CGM systems undergo rigorous testing and extensive clinical trials to ensure the accuracy and effectiveness of these alarms. However, it is crucial for users to understand that they should always confirm the glucose readings with a blood glucose meter before making treatment decisions.
What is Dexcom and how does it work?
A1: Dexcom is a leading medical technology company that specializes in continuous glucose monitoring (CGM) systems. Its CGM devices, such as the Dexcom G6, use a small sensor placed under the skin to measure glucose levels in real-time. The sensor sends data wirelessly to a compatible receiver, smartphone, or smartwatch, providing users with accurate and continuous glucose readings, trends, and alerts. Dexcom's CGM systems help individuals with diabetes make informed treatment decisions and manage their condition effectively.
Does Dexcom's CGM system need to be calibrated with a fingerstick blood glucose meter?
A6: Dexcom's latest CGM system, the Dexcom G6, eliminates the need for routine fingerstick calibrations. The G6 is factory calibrated and does not require manual calibrations by the user. However, it is recommended to perform two fingerstick calibrations within the first 24 hours of wearing a new sensor to ensure accuracy. If the CGM system alerts for a potential discrepancy, users should follow their healthcare professional's advice regarding calibration with a blood glucose meter.
Can I swim or bathe with Dexcom's CGM system?
A9: Dexcom's CGM systems are water-resistant, allowing users to swim, bathe, or shower without worry. The Dexcom G6, for instance, has a water resistance rating of up to 30 minutes in 2.4 meters (8 feet) of water. It is important to note that excessive water exposure and prolonged submersion might affect the sensor's adhesive, which could lead to inaccurate readings. Users should follow Dexcom's guidelines for protecting the sensor
How long can Dexcom sensors be worn?
A4: Dexcom sensors are designed for single-use and are typically worn for up to 10 days. After the sensor has been worn for the recommended duration, it must be replaced with a new sensor. Dexcom provides clear instructions on how to insert, wear, and remove their CGM sensors to ensure optimal performance. It is important to follow these guidelines to maintain accuracy and avoid discomfort or skin irritations.
Is the Dexcom CGM system suitable for children and adolescents?
A5: Yes, the Dexcom CGM system is suitable for individuals of various age groups, including children and adolescents. Dexcom offers the Dexcom G6 CGM system, which is approved for use by individuals aged 2 years and older. The system provides real-time glucose readings, trend information, and alerts that can be shared with caregivers and healthcare professionals. Dexcom's CGM technology offers valuable insights for managing diabetes in young individuals by helping to identify patterns and prevent extreme glucose fluctuations.
How accurate is Dexcom's CGM system?
A A2: Dexcom's CGM systems are renowned for their accuracy and reliability. Clinical studies have shown that the Dexcom G6 CGM system has a mean absolute relative difference (MARD) of 9%. This means that, on average, the readings from the Dexcom G6 are within 9% of the actual glucose values. However, it is important to note that individual accuracy may vary based on factors like sensor placement, calibration, and user technique. Dexcom continuously invests in research and development to further enhance the accuracy of its CGM systems.
