Hemoglobin A1c (HbA1c)
A test that measures a person’s average
blood glucose level
over
the past 2 to 3 months. Also called glycosylated hemoglobin, the
test shows the amount of
glucose
that sticks to the red blood cell,
which is proportional to the amount of glucose in the blood.
Hyperglycemia (high blood glucose)
A higher-than-normal level of
glucose
in the blood; generally 250
mg/dL or higher.
Hypoglycemia (low blood glucose)
A lower-than-normal level of
glucose
in the blood; generally 70
mg/dL or lower.
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 an infusion set or Pod is placed and
cannula is inserted.
Insulin
A hormone that helps the body use
glucose
for energy. The beta
cells of a healthy pancreas make insulin.
Insulin on board (IOB) (active insulin)
The amount of
insulin
that is still “active” in the body from a previ-
ous
bolus
dose. In the mylife OmniPod System, insulin on board
(IOB) is considered in two parts: the Insulin on Board (IOB) from a
previous
correction bolus
and the IOB from a previous
meal bolus
.
The amount of time insulin remains “on board” or “active”
depends on each individual’s
duration of insulin
action
. Talk with
your
healthcare provider
to determine your duration of insulin
action.
The mylife OmniPod System continually calculates the Insulin on
Board (IOB) to help prevent “stacking” of bolus doses, which is a
major cause of
hypoglycemia
.
Insulin reaction (see hypoglycemia)
Insulin-to-carbohydrate ratio (IC Ratio)
Number of grams of
carbohydrate
covered by one unit of
insulin
.
For example, if your insulin-to-carbohydrate ratio is 1:15, then
you need to deliver one unit of insulin to cover every fifteen
grams of carbohydrate you eat.
In vitro
Literally, “in glass.” Refers to a biological function taking place in a
laboratory dish rather than in a living organism.
