Failed or Constant Updating Medtronic Guardian Sensors?? Watch this!

This is EXACTLY WHAT I DO to get the full 6-7 days with my Medtronic G4 Sensor with the 780G Medtronic system to reduce updating sensors and fails. I hope this is helpful for you.

This was great. I wasn’t told how Smart Guard worked when the sensor is changed and tonight is my first time changing the Guardian Four since I started. Thanks for the great explanation

Hi, for the past 4 months my daughter keep having the Updating issue after the warmup, we've tried to change the insertion area, but we were unlucky. It's getting frustrating tbh,

2 hours??
My wife’s takes 2 hours if it’s Christmas. Most of the time it between 4-8 hours. Sometimes 10 hours to update.

0:26 the title is failed sensors, yet this video though is simply how to add a new your sensor.

Cant believe you still have to charge the transmitter! I switched to tslim and dexcom 7 after being a Medtronic user for over 28 years

Has the quality of the sensor (guardian 4) changed, failures are occurring more and more

You should mention you can insert on the inside of your thigh, up high. Much easier to insert than on back of arm, less chance of catching it. Also it can go on your abdomen again much easier to insert. Medtronic approves both those sits though they do suggest back of arm as best. I have never had one expire early. I always get seven days.

What happens when it takes more than 2 hours for sensor to update?

[hansmekenkamp]

Thank you. I learned something. Greetings from the Netherlands

Both areas are too awkward to insert. I’m still using my abdomen. However, they do update and expire too early. Also when I have got it in my arm, I almost always run into a wall and it rips it right out

What a massive faff, so much hassle for a CGM! for years I wanted the Medtronic, but refused it because of all this hassle to apply one, what was Medtronic king, Dexcom G6/7 Libre 2/3 just place it in the arm and fire it on, no massive stickers everywhere! So now Medtronic has the Simplera, here in the UK, once my consultant heard this, I’m now going on the Medtronic 780g 👍

What do you think about the pump? Please do a comparison video!!

[TonytheTypeTiger]

Would you consider questions on comments thru YouTube?

I’ve been using Medtronic for almost 4 years. I’m still using the pump, but switched to Dexcom 7 for my cgm. When I used the guardian 3 sensor and the 770g pump using smart guard, I didn’t have very good control. I was usually high. So I changed to manual mode. Do you feel like the 780g and guardian 4 smart guard is better now? I have to say I do like that the Dexcom 7 is so much easier to put in, and only 26 minutes warm up, and lasts 10 days with 12 hour grace period. I’m starting to shop around for other pump options now. Thank you for your insight on this, since you are now using Metronic’s.

One recommendation, when removing the base platform from the serter, I noticed that you were quickly lifting the serter. I will lift up slowly it to help ensure that the plastic tab covering the adhesive does not disconnect from the base. Then follow up by examining inside the serter to verify the plastic was removed as is the normal sequence of events. If it did not disconnect correctly, you can then use tweezers to reach into the opening and manually remove the plastic. I would also note when charging the G4 to watch the LED flashing as the repetition rate decreases as the AAA battery voltage drops which will increase your charging time for the device. As noted, if the G4 flashes after removal charger it will still have a full charge. I state this as we all want the device to charge as quickly as possible to return the pump to normal operation. One other thing to note, when you enter a manual BS reading to calibrate the sensor if the reading on the pump is off by say 15 then the calibration will be rejected by the pump for 15 minutes. You can override this lockout by quickly reentering the BS reading again to help prevent this problem. Yes, I have done this before as if you get a second lockout then pump will probably request a sensor replacement. Another thought, when applying the liquid adhesive is you have to be especially careful not to get it on the upper part of the exposed sensor. Since there are 7 individual sensor pads with 6 that are paired for replication and the most critical bottom most sensor at the end of the inserted tab. After examination, the early sensor failures have been linked to skin tissue covering the deepest sensor preventing the body fluids from reaching that area which is visible when examined under my microscope. Your body tries to encapsulate any foreign substance which is perfectly normal, so why will some fail early is the question that is not being answered.

Since you are using the extended infusion set, then I will reference the quick set which has the exact same specs works for me and is working for the full 7 days without any problems. You can also reference the specs on the Medtronic website to verify that they are indeed identical which I have done. The problem is in step 6 for the insertion during the removal which I modified to 4-5 complete revolutions of the cap until it fully disconnects then releases and will just fall loose. The problem that I encountered was that any upward force applied on the blue cap resulted in lifting the platform upward on the needle. When inserted into the skin the plastic tubing would conform to the taper of the needle forming a donut shape which is seen after removal when viewed by a microscope. The tubing would compress the underlying tissue and would try to express the tubing upward causing premature release of the tape. You would see that the tubing was bent after removal being a sign of the problem. Using the modification in step 6, led to the tubing being straight after the removal confirming the correct installation of the quick set. I would say 99% of my problems disappeared after this revolution to me, but heavy sweating would still lead to early release of the tape. So, my trying to match up the week of sensor and life combined with the infusion set was no longer my priority, as they were still complicated with early failures of the G4 sensors.

Does Medtronic supply that overpatch as demonstrated? I recall when I used Medtronic the taping procedure was more complicated.

Wonderful video. Thank you so much for the info. I have no idea what I am doing wrong. My Sensor expires, I turn my sensor off on my pump, charge the sensor until the doc stops blinking green, I take the sensor off and turn the sensor on on the pump at the same time, the green light blinks a bunch of times, I wait for it to stop and connect it, the light turns green again and the pump allows me to start new sensor, it warms up THEN 99.9% of the time it says sensor updating that ill take an hour or so then it says it again, then again and sometimes for the entire day or longer, then the sensor will fail >.< I am so frustrated. HELP please <3.

Medtronic cgm is so behind to libre and dexcom, in just installing it. And you have to check calibration, I will stay with dexcom.
Dexcom push against to your skin press it your done.

I use my stomach. I can't wait for blood glucose (or interstitial fluids rather) reading on a watch. I've been trying to develop this but the accuracy isn't great. Come on Apple!
