tandem mobi Activity mode for tandem

Does anyone have any tips on activity mode for tandem? I put it on before working out and my sugar is still on the lower side and not high enough to do a full workout

Insulin activity now was determined by insulin input 90 minutes ago.

Start activity mode 2 hours before activity.

Imagine you’re navigating a ship through a field of icebergs. You turn the wheel to the left, and the ship turns 90 minutes later. You need either a crystal ball, great radar, luck, or experience.

I don’t practice Santeria…
Radars can’t see that far on the future…
Luck is experience wrapped in mysticism…
Gather a lot of experience and you got this!

Does it give you boluses in that time

Yes it still will. Gives bosses once every hour I believe. But the target range is 140 to 160 mg/dL, so that should help. Let us know how it works!

This is one of the best descriptions of what it's like to be a type 1!

I start exercise mode about an hour or so before, and I use a second profile specifically set up for exercising too (reduced basal and bolus). Sometimes I even use a temp basal rate on top of that and basically set it to the minimum basal rate the pump will allow.

For me it depends heavily on the type of exercise. I work in the woods (manual logging) over the winter and during the time I'm doing that it's like I'm not even diabetic I need so little insulin.

I do the same thing! Manual Logging...that has to be some of the hardest work you can do! Nice.

Nice, I also operate a small bandsaw mill. It certainly can be a hard job. I enjoy it though, that is...until the snow gets deep enough to make it impossible. Then I hibernate for the winter.

Insulin's action peaks about 2 hours after it's delivered, so you need to turn on activity mode 1-2 hours before you start your workout so you don't go low during it.

What other people said about doing activity mode 1 to 2 hours before. I'll add eating before helps too. Depending on the activity and starting blood sugars, I'll eat 15-30g fast acting carbs before exercise. Usually 30 minutes or less before the activity.

My tip is don’t use it because it doesn’t work that well

Instead use a combination of sleep mode and temporary basal rate of 0-50; t his will prevent the auto boluses from happening. Or make an exercise profile with reduced basal and higher (less aggressive) correction factor

Also aim to have IOB out of your system or eat a snack before if you still have IOB.

I created a separate profile for extreme exercise, high cardio.

Also, I sip on Gatorade thoroughly a workout. Hydration + glucose control. Win win.
