History of advancement in diabetes treatment New technology Features Pros and Cons Safety in school Questions
4
1921-It was discovered that the pancreas produced insulin 1930-Insulin was made from Pork and Beef 1935-It was discovered that there was a difference between type 1 and type 2 diabetes 1952-long acting insulin was made 1961-Single use syringes were invented 1964-First insulin pump was invented and worn as a back pack 1974-First computer controlled insulin pump was invented 1983-Medtronic released the first insulin pump into the market 1990-2000-Technology continued to miniaturize and become more user friendly and accurate 2013-First insulin pump and CGM close looped system and beginning of artificial pancreas 2015-Wide spread use of CGM and blue tooth to smart phone apps to share CGM results
6
1970’s
9
Insulin pumps use only rapid or short acting insulin They have no coverage with long acting insulin if pump malfunctions Refilled, and site changed every 3 days
10
Basic metabolic need for insulin So much an hour, 24 hours a day Can have varying amounts throughout the day Temporary basal rates-Can use for high activity days (PE, Field Days, Field Trips).
11
Used at meal time and for correcting elevated blood sugars Smart pumps help calculate how much insulin is needed taking in to account carb intake, blood glucose level, and active insulin or insulin on board Normal Dual wave or extended bolus Square bolus
14
Carb to insulin ratios Sensitivity Target ranges Active insulin time Can be set to alarm for missed bolus’s, inactivity, low battery, low reservoir, no delivery
15
More freedom from scheduled meal times, exercise, and sick days More convenient, and discrete while bolusing for meals Ability to give precise amounts of insulin Tighter control Better quality of life reported Easy and accurate dose calculations, safety mechanisms Less injections and needle pokes
16
Costly Have to check blood glucose more often Possible Allergic reactions to adhesive Possible pump malfunctions can cause DKA (battery dies, cannula kinks, scar tissue) Being attached to something 24/7
17
Infusion set Reservoir Insulin Skin prep items Pump batteries Inserter Manufacturers manual, alarm card Syringe (In case of malfunction)
18
Always follow the doctors orders If questions, call parents or caregiver If blood glucose does not respond to correction bolus of insulin and student is feeling ill the pump may not be working correctly or the tubing may be kinked If pump or set malfunctions insulin will need to be given by injection If student is unconscious with low blood glucose the pump should be disconnected and glucagon given
19
Soreness, redness or bleeding at infusion site Leakage of insulin at connection or infusion site Dislodged infusion set Pump malfunctions Repeated alarms Blood sugar does not respond to bolus insulin given
21
Only 37% of patients with diabetes obtain levels of glucose control recommended by the American Diabetes Association Tight glucose control is a standard of care and is most challenging for people using insulin due to fear of hypoglycemia
27
High and Low alert Rise and Fall alert or arrows Out of range or weak signal alert Calibration alerts Thresh hold suspend feature (Medtronic) Reads glucose from interstitial fluid every 5 minutes and displays on CGM
28
CGM will have a lag time of 10-20 mins If blood glucose is moving rapidly the CGM may be off After eating or exercising CGM may be off Important to check CBG to make sure the CGM is correct before treating
31
Be patient and have realistic expectations Don’t panic if meter and sensor numbers are different Don’t react too quickly or give insulin too often Look at trends not individual number Always check a capillary blood glucose before giving insulin or treating for hypo/hyperglycemia If transmitter falls off keep in a plastic bag for parents
33
Uploader phob must be within 6 feet of pump, and 20 feet of the mobile device Phob is charged daily Download MiniMed Connect App on phone and invite followers Followers will get blood glucose information on their phones Need WiFi connection, and App open to get data Can send alert texts to others as well
34
Bluetooth wireless communication from Apple Transmitter, receiver, and I Phone, or I Pad with Share App downloaded Person following data needs to download the Follow App to receive data and can follow up to 5 people Data sent via The Cloud
35
Is built into the transmitter that the person wears Goes from there to a compatible I Phone, or I Pad Person wearing pump needs compatible device with them or the receiver.
36
Teachers should be trained to respond appropriately to CGM alarms This is in the classroom and needs to be responded to immediately Helps the teachers feel more confident in managing their classroom
119
Download App from App store onto I phone or I Pod (Android compatibility coming in the spring). Key phob needs to be within 6 feet of student, another phone at school? Alerts are sent to another phone via text message? User name and password for carelink can be shared with school nurse
120
Needs a receiver, and phone within 20 ft of student wearing pump App downloaded on phone Need WiFi connection so results can be sent and received on another phone Uses the cloud to send information Dexcom G5 will still need to carry a phone but will not need a second receiver Still needs WiFi connection
121
School nurses can download App on their phone with parental consent Can only has 5 CGM’s connected to one phone at a time Will need user name and password Responsibility?
122
Never use reading on CGM for treating hyperglycemia or hypoglycemia Always check blood glucose before giving insulin Use to alert you for the need to respond or be watching for future events If the student says they feel low and the CGM reads 200 mg/dl still check blood glucose, the CGM could be off 10-20 minute lag time
123
If the transmitter falls off at school keep in a baggy for student to take home Call parents or refer to IHP or 504 for next steps
124
A closed loop system where the CGM talks to the insulin pump which holds faster acting insulin, and glucagon in two separate vials. Will be more accurate and the pump will release glucagon when needed for hypoglycemia, and insulin for hyperglycemia Is being tested and hope to have out in 2018-2019
