Here are a couple > [@Venous Blood Glucose Sensor vs. Subcutaneous BG Sensor](https://forum.fudiabetes.org/t/venous-blood-glucose-sensor-vs-subcutaneous-bg-sensor/1629): > > [http://www.jefferson.edu/content/dam/tju/jmc/files/anesthesiology/apc/2006ASA-1.pdf](http://www.jefferson.edu/content/dam/tju/jmc/files/anesthesiology/apc/2006ASA-1.pdf) Interestingly, in this one patient study the venous sensor didn’t work as well as the subcutaneous due to sensor design issues. > [@Acetaminophen, CGM and blood sugar](https://forum.fudiabetes.org/t/acetaminophen-cgm-and-blood-sugar/1920): > > Could someone please help enlighten my addled, sick brain about why acetaminophen is not a good option? Is it that it actually spikes the blood sugar or that it prohibits the CGM sensor from taking accurate measurements? I know Ibuprofen is fine to take, but I could sure go for some Nyquil right about now. > [@Would implantable CGMs be more accurate?](https://forum.fudiabetes.org/t/would-implantable-cgms-be-more-accurate/2460): > > On the implantable CGMs… The problem I have with CGM accuracy is - I suppose from what they tell me - my body tissue is not very conducive to using the sensors. They (the Dexcom support peeps) always ask me if I am lean. Since they always ask that question, and it’s not because they are trying to hook up with me on Tinder, I guess it is a known issue for Dexcom users. Would an implanted one make a difference? Do they put it in deeper so it gets to body tissue that is more conducive to CGM use… > [@Expired Dexcom sensors?](https://forum.fudiabetes.org/t/expired-dexcom-sensors/511): > > I am curious if anyone has a good sense of how well expired sensors work, and what their effective duration truly is. I don’t mean how many days they can function when used but how many months past their due date they can be used with good expectations. What I know: Many of us routinely use sensors that have been expired for a few months Dexcom does not replace expired sensors that malfunction, but rarely asks. Does anyone have a sense of when they truly become unreliable, and how? My … If you have any specific questions or just want to understand what makes these things tick, let me know. I never get tired of talking about it, but I quickly wear out the audience in my experience. --- _[View the full topic](https://forum.fudiabetes.org/t/8th-grade-science-fair-project-meter-noise/6277)._
