Learning Objectives This course, Insulin Pump Therapy, will examine insulin pumps and their use. Discussed will be how they work, whey they are recommended to insulin-dependent people with diabetes, what to consider when outfitting a patient with an insulin pump, and patient education. Also examined will be the rationale for using a continuous glucose monitor, and how they fit into the system.
Upon completion of this program the participant should be able to:
Insulin Pump Therapy 101 In this course we will describe How insulin pumps work The pros and cons of insulin pump use vs MDI(multiple injection therapy) Strategies to help patients successfully transition to pump therapy And we will wrap with time for questions and answers.
An insulin pump is a device roughly the size of a pager that delivers insulin 24 hours a day. Pumps are powered by either disposable, internal, or rechargeable batteries. Insulin pumps are worn outside the body and infuse insulin through into the adipose tissue via some means of inserted canula or needle. Pumps are programmable down to as small as 0.025 units of insulin and can be tailored hourly for differing insulin needs through the day or night. These settings can then be changed for different needs.
Pump Evolution Insulin pumps have come a very long way since their invention, transforming from contraptions that were roughly the size of a camping backpack and completely impractical for daily use, to large syringe pump-style devices, and on to smaller, more wearable devices that had very simplistic programming By contrast today’s insulin pumps are very small and convenient to wear and are highly customizable in their programming, even using imported continuous glucose monitor data for partially automated insulin delivery.
There are three insulin pump models currently approved for use in the U.S. by the FDA. The Medtronic 770, 670, and 630 systems The Omnipod Eros or Dash systems And the Tandem X2 insulin pump.
These pumps have different features and capabilities which we will discuss later.
And before we move on, let's take a look at the different types of insulin used in these pumps. Rather than long acting insulin and short acting insulin used in injection therapy insulin pumps use only rapid acting insulins. This insulin is delivered in two days, first is a small pulse of insulin as often as every 3 minutes to deliver a background or basal insulin dose. This replaces long acting insulin entirely in pump use
Larger, Bolus doses, for meal coverage or blood sugar correction are then dosed as needed through the day.
