I recently switched to an Animas 2020 pump. I am using the Silhouette Infusion Set inserted in my abdomen. I seem to be getting a lot of occlusion errors overnight. Every time I get them there doesn't actually seem to be an occlusion in the line as I am able to prime and resume normal pumping. It seems like my pump thinks it is totall ocluded at night as I get 3-4 errors a night with a basal of 1.3 u/hr. I have never got an occlusion error during the day with the same infusion set that cause multiple errors the nigth before. I am not laying on the tubing or on the infusion site so they should be free and clear. I have also tried inserting in my buttocks and had the same behvior. As a side note, I recently lost a good amount of weight (~20 lbs) and was experiencing increased occlusion problems with my old pump (Paradigm 712) before I switched but they were not isolated to overnight only and did not occur almost every night as these have been. Has anyone out there experienced similar issues with occlusion errors overnight or have any otehr advice on what I could try to reduce these errors.
