More from Jake Leach, Dexcom Chief Technology Officer, interviewed by Scott Benner on the Jukebox Podcast, published 20 July 2021.
The answer to the big timeline question: soon. I know this is all relative. Soon for we users is something on the order of a few weeks to a few months but medical device manufacturers define it differently. Three weeks ago, Kevin Sayer, said the G7 will be available in 2022, now five months away.
Scott asked Jake about the pre-soaking tactic many of us now use on the G6. Jake answered, “with G7, you can apply a sensor and it’s going to start its warm-up period the second you deploy it.”
I interpret that to mean that any pre-soak period will constitute an overlap with an existing sensor session and will adversely affect the economics. I sure hope that their change to a 30-minute warm-up will produce much better sensor performance right out of the blocks. I sure hope that this design decision, one that pre-empts a valuable work-around for many of us, does not materially impair first-day performance. We shall see.
I’m hoping for the best and I will be able to monitor others G7 use for a few months while I use up my existing G6 supply. Their experience and comments will calibrate my expectations.
One thing that I have not seen or heard directly addressed by Dexcom principals is the application angle of the sensor. It looks like it’s at 90 degrees, a big change from the insertion angle used since way back, at least since the Seven Plus version in 2009.
Anyone else seen or heard anything different about the angle of the applied sensor wire? This could affect the comfort factor, especially for lean individuals, something I am not.
