What is Glucose? �a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates �Diabetics have trouble controlling these sugar levels, meaning they have to constantly check their levels to assure they are in a healthy zone
What is Type One Diabetes? �Type one diabetes is a disease, often called juvenile diabetes, that affects the pancreas �The pancreas produces little to no insulin, and the body’s immune system destroys the insulin-producing cells in the pancreas. �This makes patients need to constantly need to regulate their glucose levels
Patients with Type One Diabetes • Because of this disease patients must constantly prick their fingers in order monitor their glucose levels
A Solution �A way to solve the problem many diabetics face with constant finger pricking is a continuous glucose monitor �This will help limit the amount of time patients have to prick themselves
Continuous Glucose Monitoring System �Continuous glucose monitoring enables real- time glucose display and real-time alarms �This can help improve glycemic control and quality of life in patients with diabetes
SAP Therapy One method of continuous glucose monitoring is sap therapy Insulin pump therapy combined with real-time continuous glucose monitoring, known as sensor-augmented pump therapy (SAP)
SAP Therapy �The sensor helps diabetics monitor their glucose levels without constant finger pricking �Advanced functions such as bolus profiles, bolus calculators and threshold-suspend features come with this device
SAP Therapy Potential Barriers Solutions �Incorrect expectations, �Become more educated in usually closed loop systems �Discomfort from insertion �Low accuracy the system �Use correct insertion techniques �Proper calibration and cleansing methods
Implanted Glucose Sensors �Devices that are implanted into the subcutaneous layer of the tissue �Detect and send blood sugar levels to monitoring device �Last in body for typically 5 -7 days
New Trial �Patients implanted with sensor for 90 days �Implanted by doctor �Tested glucose rates for each meal with sensor through a smart app and related that to the rate taken using finger pricking methods
91% of sensor measurements were calculated to be within 20 mg/dl for reference glucose measurements of ≤ 70 mg/dl, 86% of sensor data were within 20% of reference glucose measurements between 71180 mg/dl, and 88% of sensor data were within 20% of reference glucose measurements > 180 mg/dl. Sensor Accuracy
Implanted Sensors Advantages Disadvantages �Lowers amount of finger �Needs daily calibration pricking �Lowers risk of infection �Easier to maintain healthier levels �Stays in body for longer periods of time �Must be implanted by doctor �Accuracy still is not perfected �Must be removed by doctor
Advancements �New technologies are changing the world �Soon even more sensors and systems will be created to make life better and easier for patients with diabetes
