Thanks to this discussion, I am now trying to make my sensors last longer than 3 days. how do you keep the thing charged? I kept the sensor end in place and recharged the battery for 15 minutes yesterday. I then put new tape over the whole thing. I use a minimed CGM.
I've kept mine in for longer than 3 days, but loss of battery power isn't what indicates that it's dead. The sensor just stops coming up with anything close to accurate results. Either it reports the BG as 'flatlining' or plummeting towards zero.
I think it really comes down to variations in body chemistry.
Best I got with my Navigator sensors was 75 days, no infection, irritation. It got more accurate the longer it was in. I only stopped it because I bumped it and knocked it off.
Best I've done with Dex is 20 days.
I start to itch under the skin after about 3 days,, same with the infusion set. I wish I could make the sensor last longer but the itching is so uncomfortable. I've had to change it out after 2 days because of this problem too. :(
I wonder if you're allergic to the tape? Maybe you could put down some sort of barrier before inserting?
Mine itched and drove me crazy so I use a barrier spray by 3M called Cavilon. Make sure to insert first and connect the sensor so the needle tip does not get contaminated and nothing gets in the sensor. Then spray and add the tape. I have zero itchiness now.
My sensors usually last 2 - 3 days. The last couple lasted for 6 days. Is there a trick to calibrating the sensor in order to make it last longer. I try to calibrate 3 times over a 24 hour period.
Since I started using IV3000, I've had better length and performance out of the sensor. I think the "trick" might be to cover up the "front" of the sensor (where the wire goes in the skin) sufficiently so that it doesn't move and water (from showers, etc) doesn't seep in the area too much. I really believe the placement of the IV3000 makes a difference.
Yes, this is what I think is best too. I use two pieces of 3000. First one covers the transmitter and the second covers the sensor. It's hard to get the tape off my skin after being on a week.
I change my sensors after 2 runs- 6 days. I just don't want it in for longer than that. It just seems like longer is too long to have anything in. My sensors are actually working well when I take them out. I use a iv3000 to cover mine and it never gets wet. It never gets irritated either. I think keeping it dry is the best way to make the sensors last.
Tape always gets irritated and itchy.
In Australia they are studying a sensor that stays in one year, But participants are saying they are still getting good results after year two. The entire sensor is transdermal. I would love to have one of those. Maybe in 30 years it will pass the FDA over here in the US.
The only trouble is that it has to be placed by a doctor and removed by a second procedure. Still they can just switch them out I would think, and only once every year or 2. I'm in,
Ok folks help out a new user.
Currently i'm following the directions and changing every three days. Apparently i'm a lemming.
What do you do? When you get "Sensor End" do you just say there is a new sensor and do the two hour warm-up?
How do you know when the sensor is "not working" after 12 or 20 days?
If it goes for 12 days why not 50?
BTW - I think the software that runs the CGM is pretty crappy.
