This circuit uses devices connected to the sensor that is inserted under the skin to keep collecting record blood glucose values. CGM basically noting fluctuations in blood glucose levels in constant to determine whether changes in diet, medication, treatment, or physical activity are required.
CGM has three components: sensors, transmitters, and wireless monitor like a pager. The sensor is inserted under the skin, usually on the upper arms, thighs, near and under the belly, to measure glucose levels of fluid network.
People who use insulin injections, insulin pens, and insulin pump does not have a problem finding these sites because it's basically the same. Note that the sensor must be placed two inches from the belly button and should not be placed above the skin bruises, swollen, and tender. Place the sensor is usually a quick and relatively painless.
The transmitter is connected to the sensors and sends information every ten seconds or so via radio waves to a pager-sized monitor, which then displays the blood glucose value. Transmission of CGM can be recharged and must be recharged every few days. Is waterproof and does not need to be removed while bathing, exercising and swimming.
CGM is equipped with an alarm system. This is reminiscent of the patient when blood glucose levels drop below or above the specified thresholds.
CGM is replaced every three to seven days, depending on the brand and manufacturer. After that, all the recorded data in memory by default are downloaded to your computer. This information will be analyzed and charts and graphs will be produced to represent the trend in the fluctuations in blood glucose levels.
Although the results recorded by the CGM are accurate, it still has to be checked with blood glucose monitors glucometers or from time to time for calibration.
The advantage of using CGM
While CGM does not ensure highly accurate readings and quite expensive, many patients still prefer to use this device as it allows monitoring of blood glucose levels continuously without having to prick the skin to take a blood sample. After the monitor attached to the patient, continuous readout can be obtained.
Another advantage of using the continuous glucose monitoring system is that the fluctuations and trends in glucose levels identified more constant. Also, the system can record changes in blood glucose that is easily overlooked when using glucometers and other tests.
For example, CGM can detect harmful changes in blood glucose levels overnight, between meals, in the morning, during and after exercise, after every meal, and over a span of 7 minutes. Information collected around the clock-this clock can provide important information for health care that will help them decide whether there is a need for a change in treatment, medication and lifestyle.
A shortage of
CGM system has not been perfected. Thus, the inconsistency with note is very common. To resolve this problem, the user often calibrates their CGM with blood glucose meters.
CGM is not a substitute for the glucometers. Although he can show blood glucose value continuously, glucometers still give more accurate readings.
