I started noticing this issue about 6 months ago after having my MiniMed for about two years before that. When I go to reconnect my set after taking a shower, I notice (consistently) that there is air at the end of the line (where it connects into the set). Sometimes it is just a small gap, a few millimeters, sometimes its closer to a full centimeter. I clear it with the “fill cannula” function, but sometimes I need to do this twice before drops start coming out the end.
I leave my pump running as normal while I shower (don’t suspend or anything) and usually am only unhooked for under 15 minutes. Just wondering if others have experienced this as a pump ages (or with new pumps?) and if it might be a sign of an issue. Or if maybe my basal rate is just low enough at that time of day that the pressure is not enough to push back against the air pressure? Thoughts?
