Insulin Pump

Basal Rate Intuition.

1 Comment

This morning, I woke up to a relatively flat line and a number in range.

I shuffled into the kitchen, knowing full well what I should do. I stared longingly at the coffee machine, knowing full well what I should do.

Instead, I took a seat at the table and opened up my iPhone. After I had whiled away some time, I headed back into my room and gave that dreaded swipe of the FreeStyle Libre.

I was almost expecting to see an upward trend arrow, indicating that I would need to go back to the basal rate testing drawing board and start again tomorrow. I wasn’t even too sure if I would be that disappointed, because then I would be able to validate my need for coffee.

Instead, I was pleasantly surprised to see a result that had barely moved since waking up, accompanied by a steady trend arrow.

I don’t really know what my morning basal rate is. Not since my morning routine changed a year ago. I just make small tweaks here and there, going by how my blood sugars react after my breakfast. I’ve been putting off doing a proper basal test for ages, because it’s so damn hard to wake up without coffee or breakfast. Not to mention that a basal test will only work when you wake up to levels that are steady and in range (less than 6mmol).

Since starting on the YpsoPump, I’ve been forced to make some tweaks to my morning basal rates to account for its limitation of only being able to set basal rates on the hour rather than half hour. I’ve noticed my blood sugars trending upward after breakfast recently. I’m also not as active as I once was at work, which could warrant an increase in insulin as well.

As I got ready for work, drove in and began my day, I was pleasantly surprised by the result of every single scan of the Libre.

I wasn’t expecting that diabetes would let me off this easy after just one day. Or that my basal rate intuition was this good.

With a mental ‘tick’ against my morning basal rates, my only homework for tomorrow is to drink coffee and revisit the insulin to carb ratio I’m employing to cover it.

One Messy Night.

I was ready to go to bed.

As I watched my blood sugar slowly climb into the 10s, I gave a unit of insulin to correct. Thinking about the after effects of stacking my dinnertime insulin on top of a late afternoon coffee and one of Nonna’s biscotti, I set a temporary basal rate of 150% for 2 hours to help that insulin better do its job.

I set the alarm on my iPhone for 1am and switched off the lamp on my bedside. With a nagging feeling of doubt as I turned on my side, I fumbled for my pump in the dark and gave another unit.

DURN! DURN! DURN! DURN! 

I hastily fumbled for my phone to silence the shrieking alarm, before switching on my bedside lamp again. As I swiped my Libre reader, I was half expecting see blood sugars heading into low territory.

Instead, I was actually a pleasant 13.8.

I was in disbelief. However, I thought it could be plausible after having pasta for dinner. I reached for my insulin pump, and gave a rage bolus of 3 units.

ZZZZ! ZZZZ! ZZZZ! ZZZZ!

My rage clearly wasn’t enough to fuel the delivery of this bolus, which was stopped in its tracks by a very irritating occlusion alarm that was hissing and vibrating at me for attention.

I ripped the cap off my infusion site, which revealed a perfectly clear looking site. A poke and prod around the area showed no signs of any discomfort. I primed several units of insulin out of my pump line, watching it spill over the cannula and pool around the cap to satisfy my paranoia. I held my pump line up in the air and ran it through my fingers, watching it like a hawk for signs of air bubbles.

With my paranoia satisfied, I reattached the cap to my infusion site and delivered the remainder of the bolus that my pump had cut off. I set another temporary basal rate of 150% for the next two hours, setting my alarm for 3am.

When I stirred at 2.17am, feeling rather uncomfortable, my Libre reader revealed a reading of 17.7 and rising. I hastily grabbed my pump and went to deliver another rage bolus of 5 units.

ZZZZ! ZZZZ! ZZZZ! ZZZZ!

That hissing, vibrating occlusion alarm sounded once again, stopping my rage bolus in it’s tracks.

By this point, I was furious as I flung my bed covers away from me and was forced out of bed.

Finally, I ripped the infusion site away from my stomach. There was no kink in the cannula. There were no signs of blood, bruising or bleeding on my stomach where I’d placed the site. Everything looked fine, and I was convinced I had just wasted a perfectly good site.

After inserting a fresh infusion site, setting a temporary basal rate and delivering my third rage bolus of the night, I was finally able to close my eyes.

I wasn’t surprised to learn that I’d slept over my 6.25am alarm. I gulped down my coffee, showered, and hastily threw two pieces of frozen Pane Di Casa into my bag to toast at work.

I soldiered on, reminded of just how much responsibility rests on my shoulders every day.

YpsoPump: The First Few Weeks (Part Two)

I’ve been road testing the new YpsoPump that launched in Australia last month. If you missed the first half of my review, you catch up here. 

I must admit that I was a little intimidated at the prospect of using Ypsomed’s Orbit inserter to place infusion sets on my stomach. When I last used the Animas insets two years ago, it was a terrifying experience. The insertion process with the disposable plastic insets were so clunky, leaving me with little confidence in whether my insertion was a success, or whether the cannula had kinked on the way in. I can still recall one tumultuous night where I didn’t pick up on a kinked cannula until several hours later when I had high blood sugars and moderate ketones.

Thankfully, I’m finding that the YpsoPump’s reusable Orbit inserter device does a far more efficient job. The plastic cannula that sits underneath the stomach feels much stronger than the Animas sets, which would also help with kinking as well. The infusion sets can also be inserted manually.

The area does feel a little tender after the pressure from the insertion, compared to the gentler manual Animas sets that I’ve been using. Thankfully, this hasn’t been a sign of any site failures. I’ve been cautiously doing my insertions 12-24 hours prior to switching the site, so that I’ll be able to pick up any signs of a site failure. I’ve had one bad site placement so far, and I was able to pick it up straight away (it was just a bit of blood).

I really like that if you do happen to place your site badly, you can simply clip it back onto the Orbit inserter and try again, compared to an inset which is rendered useless once it comes away from the insertion device. It’s also nice to have a reusable inserter device that doesn’t create so much plastic waste like the disposable insets.

Ypsomed’s Orbit infusion sets are cleverly designed to rotate 360 degrees. The end of the pump line clips into place over the top of the infusion site, rather than having to be clipped rigidly into the side of a set.

The downside to this design is that it is challenging to check the skin where the infusion set is placed for any signs of bruising and bleeding. I’m slowly getting used to seeing through the purple coating, with a little help from my iPhone torch.

The sets seem to stick well enough at the centre, although they do tend to come loose around the edges after showers. One thing I am enjoying is less sticky residue left on my skin after removing an infusion site.

There is a choice of Orbitsoft plastic infusion sets (6mm and 9mm) and Orbitmicro steel infusion sets (5.5mm and 8.5mm), with each available in lengths of 45cm, 60cm, 80cm and 110cm. I did try one of the steel sets, but I think I am a bit weirded out by having a needle permanently underneath my skin. While it worked just fine for three straight days, I can’t say that it was as comfortable as the plastic.

Ypsomed’s glass reservoirs hold 1.6ml of insulin, which is slightly less than the 2ml capacity of Animas and may be a consideration for people on larger insulin doses. We were told that insulin in the glass reservoirs could be used in the YpsoPump for up to 7 days, or stored in the fridge for 30 days.

I was also in disbelief as the pump continued to run for up to five minutes while I was changing the battery. There’s no more having to rewind and re prime the insulin cartridge, or worry about losing information about insulin on board. Since I stopped syncing with the mylife app and switched off the pump’s Bluetooth last week, I’m expecting to get around 3 weeks from the AAA alkaline battery.

When I caught up with one of the Ypsomed reps in Perth last week, I expressed just how much I want to hear from other people who have used new diabetes tools and technologies. Even during the pilot phase when I had no idea that I would be getting a pump, Ashley’s insights were so valuable.

People with diabetes need to be part of the conversation, and I’m super grateful that Ypsomed included us in their launch – which is especially generous considering they are relatively new to Australia.

The YpsoPump is available in Australia now. Subsidised consumables are available through the NDSS, although I’ve been told to expect a 7 to 10 day delay as my Pharmacy’s supplier doesn’t carry them. Which is understandable, given it’s a new product and the demand probably isn’t there yet.

A large group of Diabetes Educators attended pump training in Sydney last month, and Ypsomed has also been travelling around to various clinics around the country to train further healthcare professionals. So if you would like to get started on this pump, I am confident that you will be able to find a trained healthcare professional near you.

According to CDE Amy Rush of the Telethon Type 1 Family Centre in Perth, you may be able to get a YpsoPump before your pump replacement is due and Ypsomed will liaise directly with your health fund. I don’t know the details personally, but you can watch Amy’s video here.

If you haven’t already noticed the enthusiasm in this post, I genuinely am still brimming with enthusiasm for this pump four weeks in. I think the size, weight and sleekness of this pump are the real selling points for me.

After the pump complacency and health insurance issues that I’ve dealt with recently, the YpsoPump could not have come along at a more perfect time to help me feel re-energised in the daily grind. I officially ordered a second box of infusion sets last week, and am feeling quite optimistic about our future together.

YpsoPump: The First Few Weeks (Part One)

I’ve been staring at my chunky old Animas Vibe with its holes in the coating and an interface from the ‘90s, thinking about how I will possibly be able to while away another two years before its warranty is up. I’ve been dreaming up scenarios in my mind where new pump options would arrive on our shores and be rolled out to existing Animas customers sooner rather than later.

But I never, ever, really imagined that I would have one of these exciting new options in my hands so soon.

(This is the part where I tell you that Ypsomed Australia provided me with a YpsoPump and consumables to take home and trial. Followed by the part where I tell you that was no expectation that I would write, or even trial the pump itself. Followed by the part where I remind you that there’s a bias in place and that you should take my enthusiasm with a grain of salt).

I’ve been YpsoPumping for almost four weeks, and I am absolutely loving how sleek and light it is. When I started pumping insulin two years ago, I wanted it purely for the benefit on my blood sugars. I never thought that this sleekness was something that I could ever ask for, or want, in a pump.

It weighs eighty three grams, inclusive of a AAA alkaline battery and filled insulin cartridge. To put that into perspective, It’s about half the size of my wallet and a third of the size of my iPhone. Did I mention that it’s slimmer, too? I hardly notice it in my pocket when I’m lounging on the couch or in bed at night.

It’s also way quieter than my late Animas Vibe. I no longer hear the swish of insulin boluses being delivered. Or that little ‘tick’ every three minutes as the pump infuses basal insulin into my body.

The interface is made of up of predominantly symbols and numbers, rather than words, which definitely took some getting used to.

It also has a touch screen, which can only be switched on by pressing the button on the side of the pump. The main menu also has a three tap access code before you can go in and administer insulin.

Basal rates can be set in increments of 0.01 units per hour, which gives greater customisation than the 0.25 units on my late Animas. The biggest challenge for me is that they can only be set on the hour, rather than the half hour. So when I wake up at 6.30am, I can only set my elevated waking basal rate to run from either 5am or 6am, rather than my ideal time of 5.30am. I’ve been experimenting with some basal tweaks this week, and hopefully I’ll be able to work around this.

I’m also liking the vibrating reminders when my temporary basal rate is finished running. I tend to sleep over middle of the night alarms, but the pump has even woken me up during the night to let me know a temporary basal rate has finished running. It’s a really handy feature to have, reminding me to check my blood sugar and evaluate whether I need to run it for longer.

The biggest difference to my late Animas is that the YpsoPump does not contain a bolus calculator. That is contained in the companion mylife smartphone app. Or any other bolus calculating app, for that matter. So you would need to open your app, work out your bolus, and enter that number into your pump. The app then syncs with the pump via Bluetooth to obtain insulin data. At the launch event, we were told that the pump could eventually be controlled from the app.

I have no problem using a phone app to calculate insulin boluses. I’ve done it before when I’ve taken pump breaks. But I found it frustrating having to wait a good 15 seconds for the app to sync with my pump so that I could do a bolus calculation. I’m so used to being able to quickly glance at my insulin on board during the day before various activities. Not to mention that having my Bluetooth constantly switched on is a drain on both my pump and iPhone battery. As a result, I must say that I’ve been slacking off on bolus calculations.

I expressed to the rep last week that it would be helpful if the bolus calculator worked independently of having to sync with the pump. After suggesting that I could switch my insulin therapy settings to Multiple Daily Injections, I’ve been able to do just that. So long as I’m logging all of my bolus calculations and insulin doses in the app, I’ll be able to see my insulin on board without having to sync the pump via Bluetooth.

The pump can deliver insulin boluses in increments of 0.1 units, which is slightly less than the 0.05 my late Animas allowed. The bolus calculator automatically subtracts insulin on board from a bolus calculation, which might not always be necessary. It also lacks the flexibility to make adjustments to insulin to carb ratios or insulin sensitivity factors for things like physical activity. However, it is working a lot better for me in MDI mode.

I know just how hard a good bolus calculator is to find, and for me a diabetes app without one simply has no value. Ypsomed do appear to see the bigger picture of people who don’t use pumps and CGMs, and I’m confident that the company is working hard to make Multiple Daily Injections and glucose monitoring ‘smarter’ as well.

If you are looking for a bolus calculator, you can search for the ‘mylife app’ in your Google Play or App Store.

Come back tomorrow for part two of my review of the YpsoPump!

YpsoPump Lanches In Australia!

9 Comments

Did you just say that we’re getting a pump?

Yes.

To keep?

Yes. If you’re going to write about it, you need to know all of the facts.

All of the other bloggers were convinced that I must have misunderstood Ypsomed Australia’s General Manager, James Mayjor. I was convinced that perhaps he was just leading me on.

I walked away with the brand new YpsoPump, that officially launched in Australia today. Consumables are listed on the NDSS, meaning that Ypsopumpers will be able to access subsidised supplies just like any other pump.

I believe that a large group of Diabetes Educators will also be coming to Sydney for pump training over the next two days, so if you are thinking of starting on the Ypsopump there’s a good chance you’ll be able to find a trained CDE near you.

So, disclosures. My Life Diabetes Care covered my travel expenses and accommodation in Sydney to attend the launch of the Ypsopump. The team from My Life Diabetes Care kindly gave us a platform for the consumer voice to be heard, as well as hearing all sorts of crazy dinner conversations last night! If that wasn’t generous enough already, I was also given a Ypsopump, some infusion sets, reservoirs, pump cases and an inserter to trial.

So before you read any further, there is a pretty big bias in place. However My Life Diabetes Care have not paid for my time or my words which are, as always, my own.

First up, hooray for new pump choices in Australia!

Secondly, I honestly cannot believe just how sleek and lightweight the Ypsopump is compared to my chunky Animas Vibe that’s looking increasingly like something from the last decade. The My Life Diabetes Care team did highlight that the Ypsopump had been designed to fill the gap in a market filled with complex, medical looking devices.

I was also most impressed to hear about the My Life Diabetes Care portfolio of products, which included things like needles, pen injectors and blood glucose monitoring for people on Multiple Daily Injections and Structured Blood Glucose Monitoring. The tech is not for everyone, and offering choice to consumers is extremely important.

The pump is touch screen, although not a full colour pump. The biggest difference to my late Vibe is that the bolus calculator is not contained in the pump itself, but rather done in the My Life Diabetes app. So, I would calculate my bolus in the app, and then administer the recommended dose using the pump. The pump then connects all of my insulin dosing data to the app via a Bluetooth connection.

Infusion sets come in either steel or teflon, are available in a variety of lengths, and also have the option of manual insertion. Another noticeable difference for me compared to the Animas was the lack of a 45 degree angled cannula.

If you hadn’t noticed my enthusiasm already, I obviously hooked up straight away. It’s still very early to draw any more conclusions, but I will have more to share in the coming weeks. For the time being, I’m more than happy to stow my late Animas Vibe away in my pencil case.

P.S. A photo where I’m actually smiling!
