Guardian Sensor 4 and Medtronic 780g: Seamless Integration

According to the American Diabetes Association, nearly 37 million Americans who account for 11% of the country’s total population, are presently living with diabetes. In many of these cases, regular monitoring of blood glucose levels is necessary to adjust the dose of insulin. In this regard, seamlessly integrated Medtronic 780g insulin pumps and Guardian Sensor 4 are recommended to employ.

In this article, we will go through the seamless integration of Guardian Sensor 4 and the Medtronic 780g MiniMed pump. In addition, some of the well-known CGM brands have also been linked for the reader’s convenience.

What is the Medtronic Guardian Sensor 4?

Medtronic Guardian Sensor 4 is a continuous glucose monitor that is employed for the estimation of blood glucose levels. This is a single-use, wearable system that is inserted under the skin, where it can reach the interstitial fluid and detect BGL from it. As the sensor works 24/7, a continuous estimation of the sugar levels becomes possible.

Features of the Medtronic Guardian Sensor 4

Some of the prominent features of these Medtronic Guardian sensors have been summarized in the given section:

  • Single-use sensor to be disposed of after a 7-day wear time
  • The three-piece design includes a sensor, an inserter, and a transmitter
  • Multiple sensor placement sites, including the abdomen, arms, and upper buttocks
  • Quick usage after the initial sensor warmup time of 2 hours
  • Water-resistant sensor until a depth of 2.4 meters (8 feet) for up to 30 minutes
  • Compatibility with smartphones, smartwatches, and Medtronic 780g MiniMed Insulin pumps
  • In-the-moment BGL alert feature notifies the user in case of low, high, or urgent low sugar level (i.e., 3.1 mmol/L)
  • Predictive alert feature notifies about BGL highs and lows within the next 60 minutes
  • Alert convenience settings allow alert silence option (insulin pumps only) as well as snoozing option for highs and lows
  • No need for fingerstick calibration
  • Compatible with relevant data sharing apps, such as the CareLink Connect app

Among several Medtronic diabetic care products, the Medtronic 780g insulin pump is one of the advanced insulin pumps used for the management of type 1 diabetes. The device has a SmartGuard technology that can automatically correct the amount of insulin being delivered to the patient based on the fluctuations in their BGL. These devices are considered ideal for patients who need 8 or more units of insulin per day.

Features of Medtronic 780g Insulin Pumps

Some of the prominent features of these Medtronic 780g insulin pumps have been summarized in the given section:

  • High reservoir capacity to hold up to 300 units (3.0 mL) of U100 rapid-acting insulin
  • The SmartGuard technology for an automatic adjustment of insulin doses based on the recorded BGL data
  • Automatic delivery of correction boluses every 5 minutes due to Meal Detection technology to manage highs from carbohydrate consumption
  • Seamless integration with the Medtronic Guardian Sensor 4 for receiving BGL updates every 5 minutes
  • Water-resistant system until depth of 2.4 meters (8 feet) for up to 30 minutes

What Does a ‘Seamless Integration’ Mean?

The term seamless integration means the connection of two different devices containing different software and systems in a way that they work together in a smooth fashion. As a result of this assemblage, a unified system is actualized that reduces the risk of manual errors while increasing the process efficiency and productivity.

Medtronic Guardian Sensor 4 with Medtronic 780g Insulin Pump: Why is Seamless Integration Necessary?

The Medtronic 780g insulin pump, when used with the Guardian Sensor 4, creates an automated insulin delivery system that administers the hormone in the right dose needed by the patient. Here, the Medtronic Guardian Sensor 4 takes the job of measuring and recording the patient’s blood glucose level on a continuous basis.

This recorded BGL data is used by the Medtronic 780g insulin pump. Here, the SmartGuard technology of the insulin pump re-evaluates and auto-adjusts the dose of insulin to be administered to the patient based on the received BGL data. As the BGL data from the CGM sensor 4 comes every 5 minutes, multiple micro-adjustments are done in the insulin doses through the day.

How Does a Seamless Integration Benefit the Patients?

You might ask why the seamless integration of Medtronic 780g insulin pumps with the Guardian Sensor 4 systems is emphasized. The process is considered necessary as the following benefits can only be achieved when the two devices in question work in a closed-loop:

Proactive Management of BGL Fluctuations

Throughout the day, a person’s blood glucose level keeps on fluctuating. For a healthy individual, these fluctuations remain within the normal range. However, for someone dealing with diabetes, BGL fluctuations are more likely to rise above or fall below the pre-set target range. In such cases, the long-term side effects can be devastating, leading to diabetic retinopathy, neuropathy, cardiovascular disorders, etc.

Here, the role of Medtronic 780g insulin pumps and the Guardian Sensor 4 becomes important. The sensor continuously measures the ever-changing BGL levels and signals the Medtronic 780g insulin pump, which, in turn, adjusts the basal insulin before its administration. This way, possible highs and lows in the BGL are anticipated before they occur or become severe.

Increased Time in Range

Time in range or TIR is a measure of the percentage of time a patient’s blood glucose levels remain within the healthy target range, i.e., typically 70 to 180 mg/dL or 3.9 to 10.0 mmol/L. As the parameter gives a better picture of a person’s diabetic condition, it is considered even more accurate than the HbA1c.

When a Medtronic 780g insulin pump is used as an integrated system along with the Guardian Sensor 4, the assembly tends to maximize TIR for a diabetic patient, leading to better glucose stability as well as an improved quality of life. The SmartGuard technology of the Medtronic 780g insulin pumps is claimed to help users achieve a 70 to 80% TIR.

Reduced User Input

When the BGL results are estimated with the help of fingerstick tests followed by manual delivery of insulin doses, there is a high risk of manual dosing errors. This is because this process requires huge input from the patient in terms of calculating the right doses.

In case of using the Medtronic 780g MiniMed pumps along with the Guardian Sensor 4, the need for manual dose calculation gets eliminated as the device can automatically take the BGL readings from the sensor and adjust the dose. Therefore, the user can enjoy more freedom.

Continuous Glucose Monitors at Health Supply 770: Features and Specifications

Regular monitoring of blood glucose levels is essential to look into how well the patient’s diabetes is under control. Previously, fingerstick tests were used for this estimation, which caused pain and discomfort to the patients. Keeping this in mind, continuous glucose monitors have been designed to allow 24/7 measurement of BGL while eliminating the need for frequent finger pricking.

However, when it comes to learning about the Guardian Sensor 4 and the Medtronic 780g MiniMed pump, it is also essential to look into some of the products that many brands manufacture. Some of these well-known continuous glucose monitors are also available at Health Supply 770 and have been detailed below, along with their features and purchase links:
