Thanks for the reply. I'll be putting a new saline reservoir in later in the week. Sounds like it's probably best to leave the battery in for nowIf you take out the battery, you'll need to reprogram the pump when you decide to use the saline later in the week.
If you leave the battery in, will there be enough saline in the reservoir, or can you fill another reservoir with saline? I never used saline, so don't know what goes on.
Thank you! This is my first insulin pump so just getting used to it all. I've left the reservoir out overnight and no alarms so far. The pump thinks there's about 80 units left and with the saline solution it's set on about 7 units a day basal so I'm hoping I have a few days left before it starts alarming (by which time id be connecting it all again ). Appreciate the adviceHi lyndsayob,
You'll need to check how you've got your Medtronic 640G setup, ma'am, and look at the front panel to see how much charge there is remaining in your battery.
I've personally found that if there is insufficient charge remaining in the battery that taking it out and putting it back in it will refuse to light up the screen, and start alarming that you need to replace the battery.
Obviously, we don't know what sort of basal rates you've programmed into your 640G, so it would be difficult to ascertain as to how long it will be before it starts alarming at you. (I've set mine up to also indicate if it's been 3 days since I changed my reservoir, and also alarm if there's less than 15 units of insulin present.)
If you do decide to keep your pump running with no insulin present, be sure to rewind it as though you were going to carry out a fresh infusion change. That would give you a few days ... or even longer, dependent on your insulin sensitivity ratio (that's how much a measured amount of insulin would lower your blood glucose level by) ... before it alarms to tell you that your reservoir needs replacing.
Have you used another pump prior to the 640G, ma'am? If you have, your diabetes support team ... doctor/endocrinologist, diabetes specialist nurse, certified diabetes educator ... would be able to advise you on what your insulin sensitivity ratio is. This is a very important thing for you to know as you're MORE THAN LIKELY going to need to make adjustments to your basal rates and/or your bolus rates.
I wish you well, lyndsayob, and hope that you get to love your 640G as much as I've love all of my different Medtronic pumps over the years.
Lots of Love and Light.
Mick
