Bolus
There are three bolus types: Normal, Square Wave
®
, and Dual Wave
®
. This section gives instructions for a
Normal bolus using the express bolus button and navigating through the menus. (For information about
Square Wave and Dual Wave boluses, refer to the Optimizing pump therapy chapter.) 
The Normal bolus delivers an immediate food or correction bolus. It can be delivered at any time except
during another Normal bolus. During a Normal bolus, most pump features are disabled until after all the
bolus has been delivered. The suspend function and the STATUS screen, however, are always available. 
Setting the Normal bolus
Normal bolus can be used to cover the carbohydrate in a meal or snack and/or to correct a blood glucose
that is higher than your blood glucose target.
 
The following instructions are for a Normal bolus when the Bolus Wizard feature is turned off.
1
Go to the BOLUS MENU.
Main > Bolus
Select Set Bolus and press ACT. Go to step 2.
You can also use the 
 EXPRESS BOLUS button to get to step 2. Press 
 from your HOME screen.

a. If the SET BOLUS screen appears: (Dual/Square option is off) Go to step 3.
b. If the BOLUS TYPE screen appears: (Dual/Square Wave is on) Select Normal Bolus and press ACT.
Go to step 3.
3
The SET BOLUS screen (or SET NORMAL BOLUS screen if the Dual/Square option is on) appears with 0.0
unit bolus amount flashing.
Enter your bolus amount and press ACT.
NOTE: 
If you have BG Reminder turned On, a BG REMINDER DURATION screen displays. It allows you
to set the length of time after this bolus before you are reminded to check your blood glucose. See
the BG Reminder section in this chapter for information about this feature.

The BOLUS DELIVERY screen appears and the Normal bolus starts. The pump will beep/vibrate at the
start of the bolus. As the bolus delivers, the amount shown on the screen will increase until the entire
bolus has been delivered. When the bolus is finished, the pump will beep/vibrate again and the HOME
screen will appear.
The following practice lessons will help you understand this pump feature.

Normal meal bolus using the exchange system
Normal bolus can be used to cover the carbohydrate in a meal or snack and to correct a blood glucose
that is higher than the target that was chosen for you.
Fred has been taught that he needs to take 1 unit of insulin for every carbohydrate exchange that he
eats (every milk, every starch or every fruit). For lunch today he will eat:
Turkey sandwich with two slices of bread 2 starches
1 small apple 1 fruit
1 cup of non-fat milk 1 milk
__________________
Total carbohydrate exchanges = 4
Fred's lunch has a total of 4 carbohydrate exchanges so he will take a meal bolus of 4 units for his lunch.
Bolus practice:
NOTE: 
Make sure that you are not connected to your pump while
practicing.
 
Going through the menus, program a 2.0 unit Normal bolus now.
Check here if you were able to program it.

Normal meal bolus using carbohydrate counting
Lydia has been taught that she needs to take 1 unit of insulin for every 10 grams of carbohydrate. This is
her insulin to carbohydrate ratio. For dinner she will have:
4 ounces broiled chicken   0 grams
2/3 cup of rice 30 grams
1/2 cooked broccoli   5 grams
1 ounce dinner roll 15 grams
1 tsp margarine   0 grams
__________________
total grams of carbohydrates = 50 grams
Lydia's dinner totals 50 grams of carbohydrate. Her insulin to carbohydrate ratio is 1 unit: 10 grams. She
will take a meal bolus of 5 units for her dinner. She determined this by dividing 50 (total grams of
carbohydrate) by 10 (insulin to carbohydrate ratio).

Meal bolus, correction bolus and insulin sensitivity
Jason is ready to eat his breakfast. He has calculated that he will need 4.0 units for his food.
He tests his blood glucose and finds that it is 200 mg/dL (11.1 mmol/L). Jason knows that his blood
glucose level is above his blood glucose target and will need additional insulin before he eats.
Jason's healthcare professional has determined the following for him:
Target BG:  110 mg/dL (6.1 mmol/L)
Insulin sensitivity
1
:  36 mg/dL (2.0 mmol/L)
Jason determines that he will need a correction bolus of 2.5 units insulin to lower his elevated blood
glucose. The 2.5 correction bolus will lower his current blood glucose of 200 mg/dL (11.1 mmol/L) to his
target of 110 mg/dL (6.1 mmol/L).

elevated blood glucose: 200 − 110 = 90 mg/dL (11.1 − 6.1 = 5 mmol/L)

correction bolus: 90 / 36 mg/dL (insulin sensitivity) (5.0 / 2.0 mmol/L) = 2.5 units
(He will add this 2.5 correction bolus to the 4.0 units of insulin that he will need for his meal bolus.
Jason will take a total bolus of 6.5 units.)
1. Insulin sensitivity is the amount (in mmol/L or mg/dL) by which blood glucose will be lowered after taking 1 unit of
insulin. Consult with your healthcare professional to determine your insulin sensitivity.

Practice: Meal bolus
You have determined your meal bolus as: _______ units.
Your target blood glucose range is: _______ to _______ (average is _______).
Your current blood glucose level is: _________.
Your correction factor is: 1 unit of insulin will drop your blood glucose _________.
You will take ________ unit(s) of insulin to correct your high blood glucose level.
Your total bolus (meal bolus plus correction bolus) is _________.
Review your bolus deliveries
You can view a list of your bolus deliveries in the BOLUS HISTORY screen. This screen shows a list of the
dates, times, units, and types for your last 24 boluses. This feature is helpful for record keeping or to
check if you bolused for your last meal.

Maximum bolus limit
The Maximum bolus (Max bolus) is a safety feature that limits the amount of insulin that can be delivered
in a single bolus. The factory setting is 10.0 units. You can specify the limit from 0.0 to 25.0 units. It is
important to discuss this feature with your healthcare professional to determine your Max bolus amount. 
 
To set the Maximum bolus limit, do these steps:
1
Go to the MAX BOLUS SETUP screen.
Main > Bolus > Max Bolus
2
Set your maximum bolus limit and press ACT.
3
Your Max bolus is set. Exit the menus.
Example 1: Max bolus
Shelby takes very small doses of insulin for her meal boluses. As a safety limit, she and her healthcare
professional reset her pump with a Maximum bolus of 5.0 units.
Example 2: Max bolus
David is a growing teenager. He loves to eat big meals and requires very large doses of insulin for his
food. He reset his pump with a maximum bolus of 20.0 units so he can take more insulin when he needs
to.
Basic programming

BG Reminder
After you deliver a bolus you may want to check your blood glucose. The BG Reminder is an optional
feature that makes the pump beep or vibrate to remind you to check your blood glucose after a bolus.
However, this reminder is not available after an Easy Bolus. Your pump is set at the factory with the BG
Reminder feature turned off. 
When setting a bolus, if the BG Reminder is on, your pump will ask you to set up the BG Reminder
Duration. This sets how long after bolus delivery you will be reminded to check your BG. This time can be
from 30 minutes to 5 hours, or NONE. The BG Reminder is not available after an Easy Bolus. 
1
Go to the BG REMINDER SETUP screen.
Main > Bolus > BG Reminder
2
Select On and press ACT. The BG Reminder is now enabled. Exit the menus.
Now, the next time you program a bolus, your pump will ask you for the amount of time after your
bolus before you want to be reminded to check your blood glucose.
When the BG Reminder goes off, your pump will beep or vibrate and CHECK BG will appear on the
screen. Your pump will beep or vibrate periodically until it is cleared (ESCACT).
When you set a BG Reminder after a bolus, the STATUS screen will show the amount of time remaining,
in minutes and hours, before the reminder goes off.
Basal
Basal insulin is required to maintain your target glucose values when you are not eating. Your healthcare
professional will calculate this rate for you. Your basal insulin accounts for approximately one half of the
body's total daily insulin requirements. Your pump mimics your pancreas by delivering insulin continuously
over 24 hours.
You can set your insulin pump to change rates during the day to match your needs. Your needs depend on
your lifestyle and insulin requirements. Some people only use one rate throughout the day, while others
find they need more. Your basal rates are made up of insulin deliveries that have start and stop times.
Once set, these rates make up your 24-hour basal pattern and are repeated daily.
Basic programming
49
Chapter 4

Start and stop times
When you set your basal rate(s) in the BASAL MENU, your pump prompts you to set the start time for each
basal delivery. The start time of one basal rate is the stop time of the previous rate. This gives you
continuous basal insulin through a 24-hour period. For basal rate 1, the start time is midnight and cannot
be changed. See the following sample graph of basal rates.
12:00 AM
Basal Rate 1
start time
3:00 AM
Basal Rate 2
start time
7:00 AM
Basal Rate 3
start time
9:00 PM
Basal Rate 4
start time
24 hours
rate 3
rate 4
rate 1
rate 2
The start and stop times of basal rates for this example are:

12:00 a.m. (00:00) to 3:00 a.m. (3:00) for basal rate 1

3:00 a.m. (3:00) to 7:00 a.m. (7:00) for basal rate 2

7:00 a.m. (7:00) to 9:00 p.m. (21:00 ) for basal rate 3

9:00 p.m. (21:00 ) to 12:00 a.m (00:00) for basal rate 4
If you need one basal insulin that starts before midnight and stops after midnight, you need to set up two
basal rates. These basal rates have the same rate but different start and stop times. For example, in this
graph a basal rate is needed from 9:00 p.m to 3:00 a.m (21:00 to 3:00) at one rate. Basal rate 1 always
starts at midnight and should be set to end at 3:00 a.m. (3:00 ). After setting basal rates 2 and 3, rate 4 is
set from 9:00 p.m. (21:00) to midnight at the same rate as basal rate 1. This gives continuous basal insulin
from 9:00 p.m to 3:00 a.m. (21:00 to 3:00) at one rate.
You cannot set a start time for one basal rate to overlap the next basal rate. The addition of a new basal
rate will erase any basal rates that follow.
Basic programming
50

For best results, setting or changing your basal rate(s) should be discussed with your healthcare
professional.
Your basal settings
You must program your basal settings before you can deliver basal insulin. Keep a written record of your
basal settings.
It is recommended that you set your basal rates with the assistance of your healthcare professional.
If you plan to take off your pump for an extended period of time, i.e. more than a day, set the basal rate
to 0.00 U/H. This will ensure that the insulin delivery records in your pump are accurate. Refer to the If
you remove your pump section in the The basics chapter for more information.

Setting the Max basal rate
Maximum basal (Max basal) rate is a safety limit for the amount of basal insulin that is able to be delivered
per hour. Your pump is sent from the factory with the Max basal set to 2.0 units per hour. It is important to
determine your Max basal rates with your healthcare professional. This safety feature will not allow you to
program any basal rates, including patterns and temporary basal rates, that are greater than the Max basal
rate.
If you are setting your Max basal rate after your basal rates have been set, you cannot set a Max basal that
is less than any of the programmed basal rates.
 
To set your Max basal rate, do these steps:
1
Go to the MAX BASAL RATE screen. The Max basal rate will be flashing.
Main > Basal > Max Basal Rate
2
Change the rate and press ACT.
3
Your Max basal rate is now set. Exit the menus.
Example 1: Max basal
Helen has a very low insulin requirement. Her highest basal rate is only 0.4 units per hour. As a safety
measure, Helen's healthcare professional set her pump with a Maximum basal rate of 1.0 units per hour.
Example 2: Max basal
Rusty needs large amounts of insulin to control his blood glucose levels. His new pump was delivered
from the factory with a Maximum basal rate of 2.0 units per hour, but he needs 2.8 units per hour in the
early morning. Rusty will reprogram his Maximum basal to 3.0 units per hour to accommodate his needs.
Basic programming
54

Stopping your pump
Suspend stops all insulin delivery including the current basal and any bolus or prime deliveries that are in
progress. While suspended, your pump will not deliver insulin until you resume your pump. When you
resume your pump, the basal delivery will continue. 
The pump will beep or vibrate about every 15 minutes on the hour to remind you that it is not delivering
insulin. Example: You suspend your pump at 11:20 a.m. The pump will beep or vibrate at 11:30 a.m.,
11:45 a.m., 12:00 noon, and so on until you resume your pump (basal resumes).
When suspended, your pump is in Attention mode with a solid circle showing on the pump. When in
