■

Safety and indications

Safety and indications 7

• Minimal blood splatter associated with sensor needle removal

• Residual redness associated with adhesive, tape, or both

• Scarring

Specific risks related to sensor use

Taking medications that contain paracetamol, including, but not limited to fever
reducers and cold medicine, while wearing the sensor, may falsely raise sensor
glucose readings and result in an over-delivery of insulin. The level of inaccuracy
depends on the amount of paracetamol active in the body and may be different
for each person. If paracetamol is taken, stop the use of the medication before
using SG readings to make treatment decisions. Use additional BG meter readings
to verify glucose levels, turn off the Auto correction feature, and consider turning
off the SmartGuard feature. Check the label of any medication to confirm whether
paracetamol is an active ingredient.

Do not use SG values to make therapy treatment decisions while the pump is in
Manual mode. SG values can only be used to make therapy treatment decisions
while the SmartGuard feature is active. SG and BG values may differ. If the SG
reading is low or high, or there are symptoms of low or high glucose, confirm the
SG reading with a BG meter prior to making therapy decisions to avoid
hypoglycemia or hyperglycemia.

For persons seven to thirteen years of age, sensor insertion is approved for in the
abdomen and buttocks. Do not insert the sensor into any other location.

For persons fourteen years and older, sensor insertion is approved for the
abdomen and back of the upper arm. Do not insert the sensor into any other
location.

Risks related to meter use

For the most current risks, see the User's Manual that came with the device.

Risks related to serter use

The serter contains small parts and may pose a choking hazard that can result in
serious injury or death.

Side effects include discomfort and skin irritation at the insertion site.

General warnings

Pump

• Do not use the pump in the presence of anesthetic mixtures that include
oxidizing agents such as oxygen or nitrous oxide. Exposure to these
conditions may damage the pump and result in serious injury.

• Always use the fingertip for blood samples intended for sensor calibration. Do
not use blood samples from the palm to calibrate the sensor. The palm has
not been studied for use with the SmartGuard feature and the performance of
the system using such blood samples is not known.

• When the SmartGuard feature is active, SG readings are used to calculate basal
insulin delivery and correction boluses. Do not use SG readings to make
treatment decisions while the pump is in Manual mode. SG and BG values
may differ. Sensor performance may occasionally vary from sensor to sensor
and in different situations for a sensor, such as on the first day of use.

A BG meter reading is required in the following situations:

■

Safety and indications

Safety and indications 9

• Before a correction bolus is given in Manual mode.

• The SG reading is lower than expected.

• The SG reading is higher than expected.

• Suspected hypoglycemia or symptoms of hypoglycemia.

• Suspected hyperglycemia or symptoms of hyperglycemia.

• Suspected diabetic ketoacidosis or symptoms of diabetic ketoacidosis.

Do not use SG readings to make treatment decisions while the pump is in
Manual mode.

• Do not rely on the pump tones or vibrations to navigate the pump screens or
menus. Relying on pump tones or vibrations may result in incorrect menu or
setting selection. Always view the pump screen when selecting menus and
entering information into the system.

• Only use rapid-acting U-100 insulin (Humalog, NovoLog, and NovoRapid)
prescribed by a healthcare professional for use with an infusion pump. Use of
any other drug or medication in the reservoir can cause serious injury.

• Confirm that the infusion set is disconnected from the body before rewinding
the pump or filling the infusion set tubing. Never insert the reservoir into the
pump while the tubing is connected to the body. Doing so may result in an
accidental infusion of insulin, which may cause hypoglycemia.

• Do not insert the reservoir before rewinding the pump. Doing so may result in
an accidental infusion of insulin, and may result in hypoglycemia.

• Do not use the MiniMed 780G insulin pump or additional system devices next
to other electrical equipment, which may cause interference. This includes
mobile communication devices such as cell phones, GPS navigation systems,
anti-theft systems, and any electrical equipment that has an output transmitter
power greater than 1W. The recommended separation distance between the

Chapter 1

• Do not unscrew or retighten the tubing connector on the reservoir while the
infusion set is connected to the body. Doing so may result in an accidental
infusion of insulin, and may cause hypoglycemia.

• Do not use standard Luer sets with the MiniMed 780G system. Only use
MiniMed reservoirs and infusion sets that are specifically designed for use with
the MiniMed 780G system.

• Do not change or modify the MiniMed reservoir or the MiniMed infusion set.
Modification of these components may cause serious injury, interfere with
device operation, and void the warranty.

• Do not rely on preset pump alarms or reminders alone to check BG levels. Set
additional reminders on other devices, such as a cell phone.

• Do not change or modify the internal RF transmitter or antenna. Doing so
may interfere with the safe operation of the equipment.

• The MiniMed 780G system is only approved for use with the Guardian Link (3)
transmitter with Bluetooth wireless technology (MMT-7911WW). The Guardian
Link (3) transmitter can be identified by the “GL3” marking on the top of the
device. Use of a transmitter not approved for communication with the pump
may cause damage to system components and may result in inaccurate SG
readings.

•If other devices that employ radio frequencies are in use, such as cell phones,
cordless phones, walkie-talkies, and wireless networks, they may prevent
communication between the transmitter and the insulin pump. This
interference does not cause any incorrect data to be sent and does not cause
any harm to devices. Moving away from, or turning off, these other devices
may enable communication. Contact a local Medtronic support representative
if RF interference continues.

• Special Precautions regarding Electromagnetic Compatibility (EMC): This body­worn device is intended to be operated within a residential, domestic, public
or work environment, where common levels of radiated “E” (V/m) or “H” fields
(A/m) exist. Technologies that emit these fields include: cellular phones,
wireless technology, electric can openers, microwaves, and induction ovens.
The MiniMed 780G system generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the provided
instructions, may cause harmful interference to radio communications.

Safety and indications

Safety and indications 11

• Portable and mobile RF communications equipment can affect the operation
of the MiniMed 780G system. If interference occurs, move away from the RF
transmitter.

• The MiniMed 780G insulin pump can generate, use, and radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. If the
MiniMed 780G insulin pump does cause interference to radio or television
reception, try to correct the interference by one or more of the following
measures:

• Decrease the distance between the transmitter and the insulin pump to

1.8 meters (6 feet) or less.

• Decrease the distance between the meter and the insulin pump to 1.8
meters (6 feet) or less.

• Increase the separation between the transmitter and the device that is
receiving/emitting interference.

• The safety of the MiniMed 780G system has not been studied in persons with
impaired kidney function. Persons with kidney disease should consult a
healthcare professional to determine if the potential benefits of pump therapy
outweigh the risks.

• Monitor for diabetic retinopathy. During the beginning of insulin pump
therapy, rapid improvement in glucose control and reduction in A1c may
result in worsening of existing diabetic retinopathy. Use of the MiniMed 780G
system has been associated with rapid improvement in glucose control.
Monitor for diabetic retinopathy with retinal eye examinations and if necessary
adequate treatment must be performed by your healthcare professional
before beginning a treatment with the MiniMed 780G insulin pump.

• The safety of the MiniMed 780G system has not been studied in pregnant
women, persons with type 2 diabetes, or in persons using other anti­hyperglycemic therapies that do not include insulin. Persons in these
situations should consult a healthcare professional to determine if the
potential benefits of pump therapy outweigh the risks.

12

Chapter 1

• The safety of using the Suspend before low and Suspend on low features in
patients who have no pump experience is not known. The Suspend before
low and Suspend on low features should not be used if insulin pump settings
have not been previously established. Insulin pump settings include basal
rates, insulin to carb ratio, and insulin sensitivity factors. Consult a healthcare
professional before using the Suspend before low or Suspend on low features.

Reservoir and infusion sets

See the user guides that came with the device for the most current warnings
related to the reservoir and infusion set.

• If insulin, or any other liquid, gets inside the tubing connector, it can
temporarily block the vents that allow the pump to properly fill the infusion
set. This may result in the infusion of too little or too much insulin, and may
result in hyperglycemia or hypoglycemia. If this occurs, start over with a new
reservoir and infusion set.

• If a BG level reading is unexpectedly high during the infusion of insulin or if
an occlusion alarm occurs, check the infusion set for clogs and leaks.

If in doubt, change the infusion set in case the soft cannula is dislodged,
crimped, or partially clogged. Consult a healthcare professional to create a
plan for rapid insulin replacement in the event this occurs. Check BG to
confirm that the appropriate amount of insulin has been administered.

• Only use reservoir and infusion sets manufactured or distributed by Medtronic
Diabetes. The pump has been tested to operate when used with compatible
reservoirs and infusion sets. Medtronic Diabetes cannot guarantee appropriate
operation if the pump is used with reservoirs or infusion sets offered by third
parties. Medtronic Diabetes is not responsible for any injury or pump
malfunction that may occur in association with the use of incompatible
components.

• The low SG alert functionality is distinct from the automated insulin dosing
function of the MiniMed 780G system. When using the SmartGuard feature,
the MiniMed 780G system has been shown to be safe and effective for its
intended use in this population. However, do not rely solely on the use of a
low SG value for “Alert on Low” or “Alert before Low” for alerts set at 2.8
mmol/L and 3.3 mmol/L. A low SG alert may not reflect the user’s true BG at
these levels, or may not alert. Do not ignore symptoms of hypoglycemia. If

■

Safety and indications

Safety and indications 13

symptoms don't match SG readings, confirm SG with a BG meter reading.
Solely relying on these SG alerts and readings for treatment decisions could
result in missing severe hypoglycemic (low BG) events.

Sensor and serter

For the most current warnings, see the user guide that came with the device.

• Keep the sensor and serter away from children. These products contain small
parts and may pose a choking hazard that may result in serious injury or
death.

• A retractable needle is attached to the sensor, and minimal blood splatter may
occur during insertion. For healthcare professionals and caregivers, cover the
sensor with sterile gauze to minimize contact with blood. Keep as much
distance as possible from the patient when removing the needle.

• Do not attempt to remove the sensor if the sensor is broken. While there is
no evidence of a sensor breaking in a patient’s body, sensor breakage can
result in serious injury. If the sensor breaks while inserted, contact a healthcare
professional for assistance to safely remove the sensor.

• Sensors are sterile and non-pyrogenic, unless the package has been opened or
damaged. Do not use the sensor if the sterile package has been opened or
damaged. Use of an unsterile sensor may cause site infection.

• Instructions for using the One-press serter (MMT-7512) are different from other
Medtronic insertion devices. Failure to follow directions, or using a different
serter, may result in improper insertion, pain, or injury.

• Keep the needle housing within sight at all times to avoid an accidental
needlestick or puncture.

• Confirm that the sensor is securely placed in the serter to avoid improper
insertion, pain, or minor injury.

• Watch for bleeding at the insertion site (under, around, or on top of the
sensor). If bleeding occurs, do the following:

a. Apply steady pressure, using sterile gauze or a clean cloth placed on top

of the sensor, for up to three minutes. The use of unsterile gauze can
cause site infection.

14

Chapter 1

b. If bleeding stops, connect the transmitter to the sensor. If bleeding does

not stop, do not connect the transmitter to the sensor because blood
can get into the transmitter connector, and may damage the device.

• If bleeding continues, causes excessive pain or discomfort, or blood is
significantly visible in the plastic base of the sensor, do the following:

a. Remove the sensor and continue to apply steady pressure until the

bleeding stops. Discard the sensor in a sharps container.

b. Check the site for redness, bleeding, irritation, pain, tenderness, or

inflammation. Treat based on instructions from a healthcare professional.

c. Insert a new sensor in a different location.

• The safety of sensor use in critically ill patients is not known. Sensor use in
critically ill patients is not recommended.

Transmitter

See the user guide included with the device for the most current warnings related
to transmitter use.

Do not allow children to put small parts in their mouth. This product poses a
choking hazard for young children.

Meter

For the most current warnings, see the User's Manual that came with the device.

Use the fingertip for blood samples collected for sensor calibration while the
SmartGuard feature is active. Only use blood samples collected from the fingertip
to calibrate the sensor. Blood samples from other locations, such as the palm or
forearm, have not been studied, and the accuracy of these samples is unknown.

Exposure to magnetic fields and radiation

• Do not expose the pump, transmitter, or sensor to MRI equipment, diathermy
devices, or other devices that generate strong magnetic fields (for example, x­ray, CT scan, or other types of radiation). Strong magnetic fields can cause the
system to malfunction, and result in serious injury. If the pump is exposed to a
strong magnetic field, discontinue use and contact a local Medtronic support
representative for further assistance.

■

Safety and indications

Safety and indications 15

Magnetic fields, and direct contact with magnets, may affect the accurate
functioning of the system which may lead to health risks such as
hypoglycemia or hyperglycemia.

• Remove the pump, sensor, transmitter, and meter before entering a room
with x-ray, MRI, diathermy, or CT scan equipment. The magnetic fields and
radiation in the immediate vicinity of this equipment can make the devices
nonfunctional or damage the part of the pump that regulates insulin delivery,
possibly resulting in over-delivery and severe hypoglycemia.

• Do not expose the pump to a magnet, such as pump cases that have a
magnetic clasp. Exposure to a magnet may interfere with the motor inside the
pump. Damage to the motor can cause the device to malfunction, and result
in serious injury.

• Do not send the pump or transmitter through an x-ray scanning machine. The
radiation can damage the pump components that regulate insulin delivery,
and may result in over-delivery of insulin and hypoglycemia.

All system components, including the pump, transmitter, and sensor, must be
removed prior to being screened with a full-body scanner. To avoid system
removal, request an alternative screening method, if necessary.

• Carry the Medical emergency card provided with the device when traveling.
The Medical emergency card provides critical information about airport
security systems and pump use on an airplane. Not following the guidance on
the Medical emergency card may result in serious injury.

General precautions

Check BG levels at least every 12 hours. Pump alarms do not notify the patient of
leaks in the infusion set or degradation of insulin. If BG is out of range, check the
pump and the infusion set to confirm that the necessary amount of insulin is
being delivered.

Waterproof capabilities

• The pump is waterproof at the time of manufacture and when the reservoir
and tubing are properly inserted. It is protected against the effects of being
underwater to a depth of up to 3.6 meters (12 feet) for up to 24 hours.

16

Chapter 1

• If the pump is dropped, hit against a hard object, or otherwise damaged, the
waterproof characteristics of the outer casing of the pump may be
compromised. If the pump is dropped or might be damaged, carefully inspect
it to confirm that there are no cracks before exposing the pump to water.

• This waterproof capability rating applies only to the pump.

• If water may have entered the pump or other pump malfunction is observed,
check BG and treat high BG as necessary using an alternative source of insulin.
Contact a local Medtronic support representative for further assistance, and
consult a healthcare professional about high or low BG levels or with any
other questions about care.

Electrostatic discharge

• Very high levels of ESD can result in a reset of the pump's software and a
pump error alarm. After clearing the alarm, confirm that the pump is set to
the correct date and time, and that all other settings are programmed to the
desired values. Following a pump reset, the SmartGuard feature will be
unavailable for five hours to allow active insulin to be updated.

• For more information on pump alarms, see Pump alarms, alerts, and messages,
on page 233. Contact a local Medtronic support representative with any
problems entering pump settings.

Extreme temperatures

Exposure to extreme temperatures can damage the device. Avoid the following
conditions:

• Temperatures above 40°C (104°F) or below 5°C (41°F).

• Insulin solutions freeze near 0°C (32°F) and degrade at temperatures higher
than 37°C (98.6°F). In cold weather, wear the pump close to the body and
cover it with warm clothing. In a warm environment, take measures to keep
the pump and insulin cool.

• Do not steam, sterilize, autoclave, or otherwise heat the pump.

Skin care products

Some skin care products, such as lotion, sunscreen, and insect repellents, can
damage the plastic in the pump case. After using skin care products, wash hands
prior to handling the pump. If a skin care product comes into contact with the
pump, wipe it off as soon as possible with a damp cloth and mild soap. For
instructions on cleaning the pump, see Cleaning the pump, on page 223.

Infusion sets and sites, sensor, transmitter, and meter

Refer to the corresponding device user guide for all warnings, precautions, and
instructions relating to the device. Failure to reference the corresponding device
user guide can result in minor injury, or damage to the device.

Adverse reactions

Refer to the sensor user guide for adverse reactions related to sensor use. Failure
to reference the sensor user guide may result in minor injury, or damage to the
sensor.

Security precautions

The MiniMed 780G insulin pump system is designed with security features to help
keep the system and the data secure. These security features in the insulin pump
system are set in the factory and ready to use when the insulin pump is received.
For example, when the pump communicates with other devices in the system,
such as the BG meter, transmitter, or compatible mobile device, the data that it is
sending and receiving is encrypted and protected by cyclic redundancy checks.
This helps prevent other people from being able to see system data, or to interfere
with insulin pump therapy.

To help keep the system secure, follow these instructions:

• Do not leave the insulin pump or the paired devices unattended.

• Do not share the pump, transmitter, or BG meter serial number.

• Do not connect the pump to any third-party devices not authorized by
Medtronic.

• Do not use any software not authorized by Medtronic to control the system.

• Be attentive to pump notifications, alarms, and alerts because they may
indicate that someone else is trying to connect to or interfere with the device.

18

Chapter 1

• Disconnect the Blue Adapter from the computer whenever it is not being
used.

• Use good cyber security practices; use anti-virus software and keep computer
software up to date.

• Refer to the MiniMed Mobile App User Guide for information on how to keep
the compatible mobile device safe to use with the Medtronic devices.

The pump only communicates with paired devices. The short time that it takes to
pair the pump with other devices is a sensitive time for security. During this time,
it is possible for an unintended device to pair with the pump. While Medtronic has
designed security features into the system to prevent this, to keep the system safe
during pairing always follow these instructions:

• Pair the transmitter, BG meter, or the compatible mobile device with the
pump away from other people and devices.

• When the transmitter successfully pairs with the pump, the green LED on the
transmitter stops blinking. If the green LED on the transmitter continues to
blink for several minutes or more after it is successfully paired, it may have
been paired with an unintended device. See Unpairing the transmitter from the
pump, on page 227 to delete the transmitter from the pump and then follow
the steps to pair it again.

• After pairing the BG meter or the compatible mobile device with the pump,
make sure that the BG meter or compatible mobile device indicates that
pairing was successful.

Consult a healthcare professional if there are symptoms of severe hypoglycemia or
diabetic ketoacidosis, or suspect that the insulin pump settings, or insulin delivery
changed unexpectedly.

If there is a concern that someone else is trying to connect to or interfere with the
device, stop using it and contact a local Medtronic support representative
immediately.

28

Chapter 2

• The tubing connector attaches to the reservoir.

• The insertion piece attaches to the body.

• The cannula is a small, flexible tube inserted into the body. Some infusion sets
use a small needle instead of a cannula.

• Adhesive holds the infusion set in place.

Change the infusion set according to the user guide provided with the infusion
set.

Reservoir

The reservoir stores insulin for delivery and is inserted into the pump reservoir
compartment.

Pump

Underneath the reservoir compartment, a piston pushes up on the bottom of the
reservoir to move insulin into the tubing, through the cannula, and into the body.

The pump delivers small doses of insulin, as low as 0.025 units. The piston inside
the pump must be rewound each time a newly filled reservoir is inserted into the
reservoir compartment.

Inserting the battery

The pump requires one new AA (1.5 V) battery. For best results, use a new AA
lithium (FR6) battery. The pump also accepts an AA alkaline (LR6) or a fully charged
AA NiMH (HR6) nickel-metal hydride rechargeable battery.

CAUTION: Do not use a carbon zinc battery in the pump. Carbon zinc
batteries are not compatible with the pump and can cause the pump
to report inaccurate battery levels.

Note: Do not use cold batteries because the battery life may incorrectly
appear low. Allow cold batteries to reach room temperature before they
are inserted into the pump.

The battery cap is located in the pump box with the accessories.

Setting up insulin delivery

Setting up insulin delivery

This chapter explains how to use different types of insulin delivery.

Setting up basal insulin

Basal insulin is the "background" insulin that the body needs throughout the day
and night to maintain target BG readings when food is not eaten. Basal insulin
accounts for approximately one half of daily insulin requirements. The MiniMed
780G insulin pump simulates a pancreas by delivering insulin continuously over
24 hours.

Basal insulin is delivered according to a basal pattern.

Basal rate

Basal rate is the specific amount of basal insulin that the pump continuously
delivers each hour. While some people use one basal rate all day, others require
different rates at different times of the day.

Basal rates are set in one or more basal patterns. Each basal pattern covers
24 hours. For specific information about basal patterns, see Basal patterns, on
page 51.

Max basal rate

The Max basal rate is the maximum amount of basal insulin that the pump can
deliver per hour. Set the Max basal rate as indicated by a healthcare professional. It
is not possible to set a basal rate, a temp basal rate, or a preset temp basal rate
that would exceed the Max basal rate limit. After the basal patterns or preset temp
basal rates are set, the Max basal rate cannot be lower than any of the existing
basal rates. The Max basal rate can be set from 0 to 35 units per hour.

4. To continue to the Max Basal Rate screen, select Continue.

5. Select Max Basal, and then set the maximum number of basal insulin units

per hour.

6. Select Save.

50

Chapter 3

Basal patterns

The basal pattern determines the amount of basal insulin delivered throughout the
day and night. A basal pattern is made up of one to 48 basal rates that are set to
cover a full 24-hour period. Because basal insulin needs can vary, up to eight basal
patterns can be set.

The following example represents one basal pattern with three basal rates set for
three different time periods.

00:00 6:00

12:00 18:00

6. Select Done.

Review the basal pattern. Press to return to the previous screen to make
changes.

Note: If is pressed and Done is not selected, the changes are
not saved.

7. Select Save.

Temp basal rates

The temp basal feature helps set and start a temporary basal rate that can be used
immediately to manage BG for short-term activities or conditions.

Preset temp basal rates can be set for recurring short term situations. For more
information on Preset temp basal rates, see Preset temp basal rates, on page 183.
The duration of the temp basal rate can range from 30 minutes to 24 hours. After

52

Chapter 3

the temp basal rate delivery is completed or canceled, the programmed basal
pattern resumes. The temp basal rates and preset temp basal rates can be defined
using either a percentage of the current basal pattern or by setting a specific rate,
as described in the following table:

Temp basal rate type Description

Percent Percent delivers a percentage of the basal rates

programmed in the active basal pattern for the
duration of the temp basal rate. The temp basal
amount is rounded down to the next 0.025 units if the
basal rate is set at less than 1 unit per hour, or to the
next 0.05 units if the basal rate is set at more than
1 unit per hour.

Temp basal rates can be set to deliver from 0% to
200% of the scheduled basal rate. The percentage
used is based on the largest basal rate scheduled
during the temp basal rate duration and is limited by
the Max basal rate.

Rate Rate delivers a fixed basal insulin rate in units per hour

for the duration of the temp basal rate. The amount
set is limited by the Max basal rate.

Starting a temp basal rate

When a temp basal rate starts, basal delivery changes to the temp basal rate for
the set duration. When the duration completes, the basal insulin automatically
returns to the active basal pattern.

To start a temp basal rate:

1.

From the Home screen, press , and then select .

2. Select Basal > Temp Basal.

3. Set the Duration.

The Temp Basal banner appears on the Home screen during delivery.

Suspending all insulin delivery and resuming basal insulin delivery

Use this feature to suspend all active basal and bolus insulin deliveries. A reminder
that insulin is not being delivered occurs every 15 minutes. The pump will beep,
vibrate, or both depending on the sound and vibration settings.

54

Chapter 3

Note: The first reminder occurs 15 minutes after the pump display times
out. If a button is pressed to wake up the pump, the reminder does not
occur until 15 minutes after the pump display times out again. To adjust
the timeout setting, see Display options, on page 149.

To continue basal insulin delivery, use the Resume Basal feature. The pump starts
the programmed basal pattern but does not start any previously programmed
bolus deliveries.

Note: To stop a bolus delivery without stopping the basal delivery, see
Stopping a normal bolus delivery, on page 68.

WARNING: If insulin delivery is suspended during a bolus, check
the pump daily history to determine the amount of insulin that was
delivered, before insulin delivery is resumed. Bolus delivery and fill
cannula do not restart when insulin delivery is resumed. If needed,
program a new bolus or fill the cannula. Failure to resume basal
insulin delivery can result in hyperglycemia and diabetic
ketoacidosis.

WARNING: Do not rely solely on the sound or vibration
notifications when using the sound or vibrate options. These
notifications may not occur as expected if the speaker or vibrator in
the pump malfunctions. A missed notification may result in the
delivery of too much or too little insulin. This is most common
when using the Easy bolus feature or when the pump is in manual
suspend. Contact the local Medtronic support representative with
any concerns.

To suspend all insulin delivery:

1.

From the Home screen, press

, and then select .

to confirm the BG meter value.

The BG received message shows.

Setting up bolus delivery

A bolus is given for two reasons: to cover food that contains carbohydrates or to
correct glucose levels that are above the target range.

About bolus deliveries

A bolus can be delivered using either the Manual bolus feature or the Bolus
Wizard feature. Multiple types of bolus deliveries are also available, including
normal bolus, Square Wave bolus, and Dual Wave bolus. The bolus type depends
on individual insulin needs. Discuss these options with a healthcare professional to
determine what is best. For details about the different types of bolus deliveries
available, see Bolus types, on page 191.

a correction bolus, or a food plus correction bolus. For more information, see
Delivering a normal bolus with the Bolus Wizard feature, on page 65.

■

Setting up insulin delivery

Setting up insulin delivery 59

The Bolus Wizard feature can also be used to deliver a Dual Wave bolus or a
Square Wave bolus. For more information, see Bolus types, on page 191.

Bolus Wizard settings

To use the Bolus Wizard feature, consult a healthcare professional to determine the
personal settings that should be used. The carb ratio, insulin sensitivity factor, BG
target, and the active insulin time are needed to complete the setup. Always
consult a healthcare professional before changes are made to the Bolus Wizard
settings. The setup procedure begins on page 61.

Setting Description

Carb Ratio The carb ratio setting is used for food bolus calculations.

The number of carb grams that are covered by 1 unit of
insulin.

Insulin Sensitivity
Factor

The insulin sensitivity factor setting is used to calculate
correction bolus amounts.

The insulin sensitivity factor is the amount that BG is
reduced by 1 unit of insulin.

BG Target The Bolus Wizard feature calculates the estimated bolus

based on the BG target range. The high and low values
set are the values to which the BG is corrected. To use a
single target value rather than a range, set the same value
for the high and low value of the BG target.

If the BG reading is above the high target value, a
correction dose is calculated. If the BG reading is below
the low target value, a negative correction is calculated
and subtracted from the food bolus.

60 Chapter 3

Setting Description

Active Insulin Time Active insulin is the bolus insulin that has been delivered

by the pump and is still working to lower glucose levels.
The pump uses the active insulin time setting to
determine if any active insulin is still in the body from
prior boluses. This may help prevent hypoglycemia
caused by overcorrection of high BG.

The current active insulin amount appears on the Home
screen and includes only the bolus insulin received.

Consult a healthcare professional to get the active insulin
time that best represents the insulin type used and the
physiological insulin absorption rate.

Reservoir and infusion set

This chapter provides information about setting up the reservoir and infusion set.

Setting up the reservoir and infusion set

Confirm that the time and date on the pump are correct before insulin is used
with the pump for the first time. For information about how to change the time
and date on the pump, see Time and date, on page 149. Consult a healthcare
professional to determine the appropriate pump settings before insulin is used
with the pump.

The following items are needed:

• MiniMed 780G insulin pump

•vial of rapid-acting U-100 insulin

• MiniMed reservoir

• MiniMed-compatible infusion set and its user guide

WARNING: Do not use the pump to deliver insulin for the first time
until the active insulin has been cleared. If the pump has been used
for training with bolus delivery before insulin is used, the active
insulin value may be inaccurate. This may result in inaccurate
insulin delivery, and serious injury. For details, see Clearing the active
insulin, on page 154.

Reservoir and infusion set

Note: Different infusion sets may have different instructions for insertion

into the body. All the procedures in the sections within this chapter must
be followed in order to change the reservoir and infusion set.

Removing the reservoir and rewinding the pump

If this is the first time a reservoir is inserted into the pump, proceed to the pump
rewind instructions. For more information about the reservoir see the reservoir user
guide.

WARNING: Always confirm that the infusion set is disconnected
from the body before rewinding the pump or filling the infusion set
tubing. Never insert the reservoir into the pump while the tubing is
connected to the body. Doing so may result in an unintentional
infusion of insulin, and may cause hypoglycemia.

When the pump rewinds, the piston in the reservoir compartment returns to its
starting position and allows a new reservoir to be placed into the pump.

The piston is located in the reservoir compartment of the pump. It engages the
reservoir and pushes insulin through the tubing.

WARNING: Do not use the reservoir or infusion set if any liquid
gets on the top of the reservoir or inside the tubing connector,
as shown in the image. Liquid may temporarily block the vents.
This may result in the delivery of too little or too much insulin,
which may cause hyperglycemia or hypoglycemia. If any liquid
gets on the top of the reservoir or inside the tubing connector,
start over with a new reservoir and infusion set.

Inserting the infusion set into the body

Always refer to the infusion set user guide and the serter user guide, if needed, for
instructions about how to insert an infusion set into the body.

WARNING: Do not remove the reservoir from the pump while the
infusion set is connected to the body. Doing so may result in the
delivery of too little or too much insulin, which may cause
hyperglycemia or hypoglycemia.

The approved areas for infusion set insertion are shaded in the following example.
Avoid the 5.0 cm (2-inch) area around the navel to help ensure a comfortable
infusion site and to help with adhesion.

CAUTION: Do not use the same infusion set insertion site for an
extended period of time. This may cause the site to become overused.
Rotate the infusion set insertion sites regularly.

CAUTION: Always change the infusion set as indicated by the
infusion set user guide. Using the same infusion set for an extended
period of time may cause infusion set occlusion or site infection.

After the infusion set is inserted into the body follow the steps in the following
section to fill the cannula.
