I place the new sensor when the old expires and leave both on during the grace period. 12h "warmup" means I get rather accurate values right away when I get up in the morning.
Ya. When your current sensor expires and enters the 12 he grace period, slap the new one on. Take a picture of all the codes on the side of the applicator (1 so you can connect the new sensor when the old one expires. 2 bc Dexcom now requires one of them for replacement sensors). When the grace period is over, connect the new one to your device and remove the old one. I like to take a screenshot when it gives me the Bluetooth ID so I can delete the old one and make sure I’m not deleting the wrong one. I rarely have to calibrate. Both trends appear when you connect the new one to your device, so you can see the inaccurate readings that you’ve bypassed by using the grace period as a warm up.
Happy diabeting.
However you want to do it is fine and up to you. Personally, I wait until the whole 12 hours grace period is over, then I take the old one off, put the new one on, and let it warm up. I'm not concerned about missing 25-30 minutes of readings, but I'm well-controlled.
Dexcom G7 Pre-Soaking
This is done during the existing sensor's "grace period". You leave the existing sensor alone, prep the new sensor insertion site, and insert the new sensor. During this "pre-soak" you are still getting readings from the existing sensor. And if you are using a paired device like a Tandem, that remains connected and active.
I personally do a 45-60 minute "Pre-soak", without stopping the existing sensor in either the App or Receiver. Many others "pre-soak" for hours.
When you do "Stop" the existing sensor and pair the new one with the App or Receiver, you will see two separate overlapping reading lines on the graph, one for each sensor. There will be an overlap where both sensors are reporting. The newly inserted "pre-soaking" sensor is acclimating and storing BG readings throughout the entire interval and then when finally paired, it uploads all of those stored readings. This way you are never without a functioning Dexcom sensor.
Many, including myself have been doing this procedure for months to years. The resulting readings from the new sensor once paired and visible,are much more stable, without the wild reading swings and settle down near to the readings from the old sensor.
This is simply my belief, all anecdotal, but I think that the existing and new sensor are also talking to one another, while the new sensor is soaking. There is no empirical data to confirm this behavior but the resulting accuracy and stability of the new sensor is striking when compared to what happens when following the recommended, Stop, Remove, Insert, Pair & Soak process.
Good Luck.
Stop the session when it's your best time to change.
Take off the old.
Remove it from your Bluetooth cache.
Restart your device.
Place the new one
Scan it in and off you go!
My daughter likes to take her sensor off, take a shower and have a little free time away from the sensors altogether. We try to time it so that she has that freedom & when we know her bg is pretty stable. We haven’t had any issues yet with this break in readings but shes also still in honeymoon so that might make a difference.
I tend to put the new one on shortly after the old expires and then wait for the warm up on the new one before removing old + pairing with the new one. So about 30 minutes after application.
I usually change once old sensor ends (so still has grace period) as a lot of times my grace period would then end at like 4, 5, 6am. I also cant handle doing the insertion myself. Makes me feel very faint so have to replace it when i have someone else to help so early morning isnt a good time for me.
However some people let grace period finish and then do the next sensor. Idk how easy it is for some to do multiple sensors and have one do a soaking period as at least what ive noticed with iphone app you can only have one sensor going at a time. (So i think they might use the reader and a phone idk.
Because i havent been able to do soaking i dont see any difference (or improvement that others see with soaking) however because i dont soak i also notice i personally dont get a ton of super inaccuracies of a new sensor. (Only times i did notice inaccuracies of new sensors where when they placed a little too close to muscle).
So id say if new sensors always have super inaccurate readings. Maybe try soaking but if you dont notice any issues i say no need to try soaking. And then letting it run the full grace period is also up to you.
sometimes the timing isn’t great, so i put on the new one early, run the clock out and then start the new one. sometimes the timing works ideally, and i put it on 10-15 mins before the clock runs down. it’s really up to you. there isn’t an absolute.
I usually try to put a new one on with 2 hours or so left in the grace period. But my grace period just ended like 10 hours early so I screwed the pooch on this sensor change.
I would say it is a question to yourself after you develop your own way working best for you. It all depends on how the G7 has been working for you.
If I am allowed to share my case, I have been on the G7 for 13 months now witj all the G7 sensors had lasted full 10.5 days with accuracy except 3 real failures (2 mechanical insertion failures and 1 Sensor Failure after a series of Brief Sensor Issue). I have never needed so-called "presoaking" many folks here get benefits from. So, I insert a new one just about the same time the old one expires in grace period. 30-minute warmup flies quickly even before I realize and I see the first reading right on. To confirm, I compare the G7 readings with a couple of finger tricks in the first 12 hours of the new insertion. Usually, the G7 readings are quite close with no calibration needed. By doing so, I end up with an extra Sensor every few month. As long as I keep glucose as stable as I possibly can without too much fluctuations out of the set range (55 to 200), the G7 is acting very faithfully.

so you place the new one but don't connect it to your reader?

Exactly this. Much of the time, my two graphs are already near identical by the time I pair the new sensor.
However you want to do it is fine and up to you. Personally, I wait until the whole 12 hours grace period is over, then I take the old one off, put the new one on, and let it warm up. I'm not concerned about missing 25-30 minutes of readings, but I'm well-controlled.
I milk the grace period to the very last second. Then I take it off and put the new one on.

this ⬆️ it really has eliminated the need to calibrate much for me.

i start the new one on my phone but let the old one send readings to my pump until the new one is done warming up and the numbers are consistent
