Is it back to the future or forward to the past?
I’m not quite sure.
What I do know is that this month is my two-year anniversary using a Tandem insulin pump and I just went back to using my Animas Vibe. I am hoping that an older, simpler pump will ease my navigation through the current dark clouds of my Type 1 diabetes. I wrote a blogpost in late November about my diabetes life as a country music ballad and things haven’t changed much. My elderly dog is recovering well from pneumonia but struggling to move around due to arthritis and an injured foot. The cold and cloudiness of late fall continue to trap me in gloom and icy streets prevent neighborhood walks. I have been in an extended funk where my diabetes doesn’t follow the expectations of “If I do A, then B will happen.” A lot of time I do A and seemingly nothing happens. Is it the pump? Is it the insulin? Is it my behavior? Is it one of Diatribe’s 42 factors that can impact blood sugar? I am burdened by diabetes technology that doesn’t give me sufficient control over intrusive beeps and sirens.
Many of you know that when I get frustrated with my D-Life, I try new tools with the conviction that there is a solution to BG frustrations. I have added Lantus as an adjunct to pump therapy with the Untethered Regimen. I have adopted low carb diets and reset my life with a month of Whole 30. I have changed types of insulin and models of infusion sets. Wil DuBois of Diabetes Mine wrote an article this week titled “To Pump or Not to Pump with Diabetes?” and shared his feelings about the benefits of changing up your D-regimen:
“I find that any time I change from one tool to another, I do better. If I changed every two months, I’d probably stay in control. I think it’s because change makes you focus. That, or diabetes is an intelligent alien parasite that can be caught off-guard only for a short time.”
But back to the subject of this post. I am using my Animas Vibe in place of my Tandem t:slim X2. I have always relied on the Vibe as a backup pump so it is not a bad idea to road test it after two years in the closet. I figured that I would quickly miss the X2 but have instead discovered that I really like this old pump.
I was concerned that going back to scrolling for carb and BG numbers would be horrible but in many ways it is easier than using a touchscreen and navigating through multiple “Are you sure?” screens. I really appreciate the immediate bolus delivery of the Vibe. With Animas, I program the bolus, it whirrs, and delivers insulin before I can get the pump back in my pocket. With Tandem, I program the bolus, it delays for a while, micro-boluses, and eventually finishes with a confirmatory vibrate a minute or two or three later. The Animas clip is a delight with its easy attachment and actually holds the pump securely on my waistband. Temporary basals are simple to enter and a temp basal of zero does not result in an annoying warning alert several minutes later. The Combo Bolus function remembers my last setting rather than requiring a recreation of the split and duration each time. My arthritic hands are having an easier time with the Vibe buttons than with the increasingly stiff T-button on my X2.
There are lots of wonderful things about Tandem pumps but I have been one of the unlucky people who gets occlusion alarms. Most users don’t get them. The vast majority of the alarms are false. I just hit “Resume Insulin” and go on my way. Lately I have had a couple of alarms that actually required replacement of the infusion set and/or cartridge. I have done extensive troubleshooting with Tandem over the years and am on my 4th pump. Only one of those pumps did not give me occlusion alarms and it unfortunately had a defective T-button. I never had occlusions in 12 years of pumping with Medtronic and Animas.
I am tired of troubleshooting. I sometimes experience one or two occlusion alarms a week and then go a while without them. But after two years of alarms, I think about occlusions almost every time I bolus. I average 8-9 boluses per day and that is a lot of thinking about occlusions. I am tired of holding the pump with the tubing extended post-bolus to prevent occlusions. I am tired of feeling guilty for stubbornly refusing to use the Tandem case and for not changing my cartridge every 3 days. I have a low TDD of insulin and an every 3-day cartridge change results in wasting as much insulin as I use. I do replace my infusion set every 2 days.
Longterm I know that I will eventually be back to Tandem. I am probably just being a pouty and whiny problem child. Despite fewer alarms and intrusions into my life, the Vibe has not cured my diabetes but I am doing better. I am committed to Dexcom and thus don’t envision switching back to Medtronic. I am super excited about getting access to the Dexcom G6 and Basal IQ; as someone on Medicare, that should happen in the spring. Hopefully the benefits of Basal IQ and eventually Control IQ will outweigh the insulin delivery problems. An Animas pump is not a longterm option. Johnson & Johnson abandoned the pump market and there is no customer support for my out-of-warranty Vibe. If it quits working or the case breaks, I am done. Fortunately I have a lot of supplies and was recently given enough reservoirs to last for several years. I can use Tandem infusion sets by substituting the t:lock tubing with luer lock tubing.
I think highly of Tandem and have always had good customer service. Until starting to use the t:slim X2, I was never a problem child with diabetes tech and continue to believe that there is something wrong with an insulin pump that frequently quits delivering insulin. Is it the design of the pump? Is it my low insulin use? Is it random bad luck? Am I at fault? I don’t know and am at a point as Gone with the Wind’s Rhett Butler would say: “Frankly, my dear, I don’t give a damn.”
