GlossaryGlossary
is a type of carbohydrate, but it does not raise blood glucose levels as other
carbohydrates do.
Glucose: A simple sugar (also known as dextrose) used by the body for energy.
Without insulin, many cells in the body cannot use glucose for energy.
Hazard alarm: A continuous sound and a screen message from the PDM or Pod
indicating that an error has occurred or that insulin delivery has stopped. Alarms
require your immediate attention.
Healthcare provider: A professional who practices medicine or teaches people
how to manage their health.
Hemoglobin A1c (HbA1c): A test that measures a person’s average blood
glucose level over the past two to three months. Also called glycosylated
hemoglobin, the test measures the amount of glucose that sticks to hemoglobin
in red blood cells, which is proportional to the average amount of glucose in the
blood over an extended time period.
Hyperglycemia (high blood glucose): A higher-than-normal level of glucose in
the blood; generally above 13.9 mmol/L.
Hypoglycemia (low blood glucose): A lower-than-normal level of glucose in the
blood; generally below 3.9 mmol/L.
Hypoglycemia unawareness: A condition in which a person does not feel or
recognize the symptoms of hypoglycemia.
Infusing: Introducing a liquid substance under the skin into the body.
Infusion site: A place on the body where a Pod's cannula is inserted.
Insulin: A hormone that helps the body use glucose for energy. e beta cells of a
healthy pancreas make insulin.
IC Ratio (Insulin-to-Carbohydrate Ratio): Number of grams of carbohydrate
covered by one unit of insulin. For example, if your IC Ratio is 1:15, then you need
to deliver one unit of insulin to cover every een grams of carbohydrate you eat.
Insulin on board (IOB) (active insulin): e amount of insulin that is still
“active” in the body from a previous bolus dose. e Bolus Calculator tracks IOB
for you. e amount of time insulin remains “on board” or “active” depends on
your duration of insulin action setting.
In vitro: Literally, “in glass.” Refers to a biological procedure taking place outside
the body rather than in a living organism.
Ketoacidosis (see diabetic ketoacidosis)
Ketones: Acidic by-products that result from the breakdown of fat for energy. e
presence of ketones indicates that the body is using stored fat and muscle (instead
of glucose) for energy.
