Ketoacidosis (diabetic ketoacidosis or DKA)
A very serious condition in which extremely high
blood glucose
levels
and a severe lack of
insulin
cause the body to break down
fat
for energy. The breakdown of fat releases
ketones
into the
blood and urine. DKA can take hours or days to develop, with
symptoms that include stomach pain, nausea, vomiting, fruity
breath odor, and rapid breathing.
Ketones
Acidic by-products that result from the breakdown of
fat
for
energy. The presence of ketones indicates that the body is using
stored fat and muscle (instead of
glucose
) for energy.
Meal bolus (also known as carbohydrate bolus)
An amount of
insulin
administered before a meal or snack to
ensure that
blood glucose levels
stay within the desired BG goal
after a meal. The OmniPod System calculates a meal bolus by
dividing the grams of carbohydrates you are about to eat by your
insulin-to-carbohydrate ratio
.
Multiple daily injections (MDIs)
Introducing
insulin
into the body with a syringe several times a
day.
Occlusion
A blockage or interruption in
insulin
delivery.
Prime bolus
An amount of
insulin
used to fill the
cannula
, preparing it to
begin delivering insulin under your skin.
Protein
One of the three main energy sources in food (the other two are
carbohydrate
and
fat
). Protein is necessary for the growth, main-
tenance, and repair of body cells and tissues. Protein contains 4
calories per gram. Foods high in protein include meat, poultry,
fish, legumes, and dairy products.
Reverse correction (negative correction)
Using an individual’s
correction factor (sensitivity factor)
, the
reverse correction is a calculation that reduces a portion of a
meal
bolus dose
when the patient’s
blood glucose level
is below
their
blood glucose target
. This feature is an option in the
OmniPod Insulin Management System, which should be turned
on or off according to the advice of a
healthcare provider
.
Sensitivity factor (see correction factor)
It is important to rule out ketoacidosis when you
experience symptoms that might otherwise indicate
the flu.
