Anyone using CamAPX FX

[PHopwood]

Hi I currently have a TSlim with Control IQ it works really well for me, my TIR over the last 3 months has been 94%.
My pump end of life is July this year, I have been offered CamAPX Fx, which offered a number of advantages.

But I have a concern that the automation element of the algorithms may not be right for me, I don't want to affect my TIR, and endup with 4 years of reduced control. But I like some of the options CamAPX FX offered.

I have asked for a months trial, to see how it would work for me, but unfortunately this is not an option.

So my question is has anyone else got CamAPS FX and how do you find it.

All the best.
Peter

Camaps it one of the best algorithms based off aaps which was around long before the likes of tandem

For me there are 2 issues 1 it's android only

2 the pump only hold 180u,

I think there is little info on camaps at the moment but if you research aaps you will get more info how it works

The latest info claims CamAPS FX will be IOS compatible in March 2024, but it has been two years since it was last promised in 2022. This site provides a good level of info too https://theglucoseneverlies.com/automated-insulin-delivery-systems-aids/

Thanks yes I have used AAPs in the past so I do understand it, but the CamAPS is a little different in the way it works. 180 units is a concern, but only when I am unwell, my daily insulin is around 52 units. So most of the time it will be OK.

There is very little information for CamAPS FX and how the algorithms works. This is why I asked for a trial.

CAMAPS is categorically not based on AAPS. The model it uses is Roman Horvorka's IP and it has never been linked.

Having said that, I've trialled CamAPS and it gave me as good results as open source offerings so I don't think it's bad.

There's some info on how the algorithm works here: https://www.diabettech.com/camaps-fx/camaps-a-month-in-review/

Hello, I use camAPS FX and it's working really well. I have 82% time in range which is far far above what I was seeing previously on a Medtronic 640G pump and an Animas Vibe prior to that.

The 160 unit capacity is not really an issue. I am on around 90 units a day. Cartridges are prefilled NovoRapid which you can get on your prescription. You can change the cartridge without having to change the tubing or the canula. You can also change the canula and the tubing without having to change the cartridge. It's not a big deal.

The Android/IOS thing is more annoying. I need to carry around 2 phones like a drug dealer which is especially jarring in the Summer when I tend to wear looser shorts.

The sooner they get that app out the better. But the improved glucose control makes carrying 2 phones worth it by some distance. You can live with it.

Many thanks ColonelRatsy,

Was you on a pump before and if so which one.

I am still undecided between TSlim and CamAPS, it sounds like the small capacity size is a none issue, as long as I remember to take a spare. I have been running the CamAPS app in demo mode, but capturing real Dexcom data and it looks like it will work. The algorithm is less predictable than the tslim algorithm, but this would be because CamAPS is not really controlling the pump it is just showing what it would do.

Are you using Libre 3 or Dexcom with your pump.

All the best.

Sorry ignore my question about which pump you were on, I missed the fact you had already told me.

I am using Dexcom G6. I prefer it to Libre, it stays on a lot better and I find it more accurate in the extremes. I would find Libre to jump to highs or lows and then correct itself retrospectively whereas the Dexcom is more reliable. I haven't lost a single Dexcom since I started in November 2023 whereas Libre I would lose probably 1 in every 3 or 4 by just taking off a jumper or walking into a doorframe.

94% time in range is pretty impressive. Congrats.

My diabetes has always been very challenging. I have a very pronounced dawn phenomenon, am very sensitive to exercise and have very high insulin tolerance. I have to take Metformin as well as insulin. So for me 82% is an achievement. I can't say for certain that CamAPS will work better for you than Control IQ since I haven't tried that. But for me CamAPS has been very positive.

Hope that helps.

Hi,

I originally posted my question about CamAPS / Dana back in March 24 before I had to order my new Pump, it seems like a while ago. But I got my CamAPS / Dana a year ago and I am very happy with it, but I will say it does not work for me as well as my tandem did but only in one way and this is a very general thing.

I feel, I am very sensitive to basal, and because the CamAPS algorithm calculates the basal it can take a while to catchup with my needs. Also CamAPS has a habit of shutting down basal after a bolus, for a long time, which allows my BS to race up, then by the time CamAPS realises, it can’t catch up, it is too late and then my BS will be above 10 for hours.

Whereas the tandem used my defined set of ratios and basals, and by using multiple profiles I felt I had more control.
I have to say if CamAPS / Dana had been my first pump after injections for year, I would have thought it was the best thing since sliced bread.

So this is a comparison of detail over the last 2 year (more of less, it is 356 days each) The last 12 months on my CamAPS and the same period of time for the previous 12 months on my Tandem.

In my head the main difference here is the CV, I am not too worried about the TIR, it used to bother me but in reality, the difference is not significant. The CV does concern me more, I know there is not much I can do about it as it is just the way the algorithm works.
