CGM devices help patients and healthcare providers track blood sugar levels continuously.
FREMONT, CA: Continuous glucose monitoring is wearable equipment that allows diabetic patients to track their blood sugar levels throughout time. Blood glucose monitoring reveals how much and when the patient's body needs insulin. Blood sugar levels that fluctuate a lot can harm a patient's health in a variety of ways. When blood sugar levels are excessively high or low, they can be dangerous and even life-threatening if not handled promptly.
Here’s how continuous Glucose Monitoring (CGM) devices work:
A small sensor is placed under the patient’s skin, mostly under the arm or belly. Adhesive tape is used to keep this sensor intact.
The sensor detects glucose levels in a patient's subcutaneous fluid. Throughout the day and night, most CGM devices take readings every five minutes. The device determines the necessity to replace the sensor on a regular basis. Sensors for most devices must be replaced every 7 to 14 days at home. For specific long-term implantable CGM devices, the healthcare professional will replace the sensor in their office a few times (or less) every year during a procedure.
A transmitter is used in all CGM systems to wirelessly convey glucose data from the sensor to a device where it can be viewed. Some CGM systems have a reusable transmitter that connects to each fresh sensor. The transmitter is included in the disposable sensor for other CGM systems.
The glucose data from the sensor is transferred to a handheld device called a receiver, an app on the patient's smartphone, or an insulin pump, depending on the CGM system.
Data from the CGM can be downloaded to a computer at any time. Some CGM systems send data on a continual basis. Patients can also share the information with their providers.
CGM machines are intricate little machines. They do necessitate some preparation time in order to comprehend their technical components. Understanding how a CGM device works takes time and patience. It is not essential for the patient to do it alone. A CGM device will be prescribed by their doctor. After the patient receives a CGM, a trained specialist will assist them in learning how to utilize it properly. The provider may also suggest enrolling in a diabetes education program or speaking with a trained diabetes educator one-on-one.
