Basal
■ Basal Basal Basal insulin is the "background" insulin that you need throughout the day and night to maintain your target blood glucose (BG) values when you are not eating. Your basal insulin accounts for approximately one half of your daily insulin requirements. Your pump mimics a pancreas by delivering insulin continuously over 24 hours. Note: In Manual Mode, your basal insulin is delivered according to your programmed basal pattern.
Basal insulin settings Your basal insulin delivery settings are described in the following table. Setting Description Purpose Basal Pattern A basal pattern is a set of one or more basal rates that cover a 24-hour period. A basal pattern lets you vary your basal rate according to your needs. You can set up to eight basal patterns. To set up basal patterns, see Adding a new basal pattern, on page 67. To start a basal pattern, see Changing from one basal pattern to another, on page 70.
Max Basal rate Max Basal rate limits the amount of basal insulin that can be delivered per hour based on the maximum rate you set. You are unable to set any basal rates, temp basal rates, or preset temp basal rates that exceed the max basal rate amount. You can set your max basal rate from 0 to 35 units per hour. Set your max basal rate as prescribed by your healthcare professional. 1. Press and go to the Max Basal/Bolus screen. Options > Delivery Settings > Max Basal/Bolus 2.
Example 2: Max basal Rusty needs large amounts of insulin to control his BG levels. His new pump was delivered from the factory with a max basal rate of 2.00 units per hour, but he needs 2.80 units per hour in the early morning. Rusty plans to consult his healthcare professional about increasing his max basal rate to 3.00 units per hour to accommodate his needs. Basal patterns Your basal pattern determines the amount of basal insulin you receive throughout the day and night.
Adding a new basal pattern This procedure shows you how to add a new basal pattern. To add a new basal pattern: 1. Press and go to the Basal Pattern Setup screen. Options > Delivery Settings > Basal Pattern Setup Basal 2. ■ The Basal Pattern Setup screen appears. Your active basal pattern appears with a check mark and the 24-hour delivery amount, as shown in the following example. If this is your first time setting up a basal pattern, the unit amount is 0.0. Select Basal 1 and go to step 5.
4. Select a basal pattern. An edit screen appears for the pattern you selected. The following example shows the Edit Workday screen. 5. To create one continuous 24-hour basal rate for your basal pattern, continue with this step. To create more than one basal rate for your new basal pattern, go to step 6. 6. a. Leave End time at 12:00 AM to set a 24-hour rate. The Start time of the first time segment is always 12:00 AM. b. Set your rate in units per hour. c. Go to Step 7.
■ The Start time for the next rate is always the same as the End time of the previous rate. Basal Note: If you need to make a change, press to scroll up to the rate and adjust the End time or Rate values. Press or when a field is selected to adjust the value of that field. When there is no field selected, press or to scroll up or down the list of basal rates. b. 7. Continue to set rates for different time periods as needed.
To activate your basal pattern, see Changing from one basal pattern to another, on page 70. Editing, copying, or deleting a basal pattern To edit, copy, or delete a basal pattern: 1. Press and go to the Basal Pattern Setup screen. Options > Delivery Settings > Basal Pattern Setup The Basal Pattern Setup screen shows all of your existing basal patterns. 2. Select the desired basal pattern. 3. Select Options. 4.
Example 1: Basal patterns Ken has had his insulin pump for about a month. He tests his BG four to six times a day and records his results in his logbook. He is happy with his glucose control during the week but on the weekends, he noticed that he has to eat more food to prevent his BG from running too low. Example 2: Basal patterns Cynthia has had diabetes for about 12 years and has been on her pump for several weeks. Every Monday, Wednesday, and Friday, Cynthia goes on a two mile walk in the morning.
Note: SmartGuard Auto Mode is not available if a temp basal is active. To switch your pump to Auto Mode, you must first cancel the temp basal. For more information on canceling a temp basal, see Canceling a temp basal or preset temp basal rate, on page 77. About temp basal rates A temp basal rate temporarily overrides all other basal programming. Your programmed basal pattern resumes after the temp basal rate delivery is completed or canceled.
Example 1: Temp basal rates Jessica enjoys her exercise classes, but finds that her glucose levels drop after she attends them. Jessica works with her healthcare professional to learn how to use the Temp Basal feature so that she receives a reduced percentage of her usual basal insulin while she exercises. Starting a temp basal rate ■ Basal When you start a temp basal rate, your basal delivery changes to the temporary basal rate for the duration you set.
• Enter a basal rate. You cannot exceed your max basal rate. 6. If desired, select Review to review your temp basal setting. 7. Select Begin to start the temp basal rate. Your temp basal rate continues for the duration you set. A Temp Basal banner appears on the Home screen during your temp basal delivery. Your scheduled basal rate automatically starts again when your Temp Basal rate finishes.
Options > Delivery Settings > Preset Temp Setup 2. Select Add New. 3. Select a name for the preset temp basal rate. For example, Temp 1, High Activity, Moderate Activity, Low Activity, or Sick. 4. Select Type to select Percent or Rate. 5. If you use Percent, enter a percentage. If you use Rate, enter the rate in units per hour. You cannot exceed your max basal rate. ■ 6. Set the Duration for the preset temp basal to be active.
To start a preset temp basal rate: 1. and go to the Preset Temp screen. The Preset Temp feature only Press appears if you have set up preset temp basal rates. Basal > Preset Temp The Preset Temp screen shows the preset temp basal rates you have set up, along with their percentage or rate amounts. Note: Depending on your active basal pattern, it is possible for a percentage preset temp basal rate to exceed your max basal limit. You cannot use a preset temp basal rate that exceeds your max basal limit.
Canceling a temp basal or preset temp basal rate You can cancel a temp basal or preset temp basal rate at any time. When you do so, your scheduled basal pattern automatically starts again. To cancel a temp basal rate: 1. From the Home screen, press and go to the Temp Basal screen. Cancel Temp Basal > Temp Basal ■ 2. Basal The Temp Basal screen shows the name (Preset Temp only), current basal rate, the set duration, and the remaining time. Select Cancel Temp Basal.
Stopping and resuming your insulin delivery Use Suspend Delivery if you need to stop all active basal and bolus insulin deliveries. While your insulin delivery is suspended, your pump beeps, vibrates, or both depending on your audio settings. This reminder occurs every 15 minutes to remind you that insulin is not being delivered. Note: The first reminder occurs 15 minutes after your pump display times out.
To suspend all insulin delivery: 1. Press and go to the Suspend Delivery screen. A confirmation message appears. 2. Select Yes to suspend your pump and stop all insulin delivery.

Bolus
■ Bolus Bolus A bolus is the amount of insulin taken to cover an expected rise in blood glucose (BG), typically when you eat a meal or snack. You can also use a bolus to correct a high BG reading. About bolus deliveries There are different types of bolus deliveries you can use, depending on your insulin needs at the time. There are also different ways you can deliver a bolus. Discuss these options with your healthcare professional to determine what is best for you.
Bolus Description Purpose Square Wave Square Wave bolus delivers a single bolus You might use a Square Wave bolus for the following reasons: bolus evenly over an extended period of time from 30 minutes up to 8 hours. • You have delayed food digestion due to type gastroparesis or meals high in fat. • When you snack over an extended period of time. • A Normal bolus drops your BG too rapidly. For details about using the Square Wave bolus feature, see Square Wave bolus, on page 101.
Bolus delivery options The following table describes the different ways you can deliver a bolus. Note: Different bolus delivery options are available depending on whether the pump is in Manual Mode or Auto Mode. For a list of delivery options available for each mode, see Modes, on page 52. ■ Bolus types How it works Normal bolus, Square Wave bolus, Dual Wave You enter your BG meter reading or the carbs you plan to eat, or both.
Delivery Bolus types How it works Normal bolus You enter your BG meter reading or the carbs you plan to eat, or both. Then the method Auto Mode Bolus Auto Mode Bolus feature calculates a bolus amount to cover the meal or correction. The Auto Mode Bolus feature is only available in Auto Mode. For details about using the Auto Mode Bolus feature, see SmartGuard Auto Mode Bolus, on page 232.
Delivery Bolus types How it works Normal bolus After the Easy Bolus feature is set up, you can deliver a Normal bolus by using method Easy Bolus feature button when the pump is in the sleep mode. ■ For details about using the Easy Bolus feature, see Easy Bolus feature, on page 107. Bolus Bolus settings The following table describes some bolus settings that you may need to change before you use your bolus options. Consult with your healthcare professional for the settings that are right for you.
Setting What it is What it does for you Bolus Increment The amount of insulin in units that is increased or decreased with each button press when adjusting your bolus amount. The Bolus Wizard feature and Auto Mode Bolus also uses the increment to display the total amount and the adjustment amount of the bolus. This setting does not apply to the Easy Bolus feature. You can set your increment value according to your typical bolus amounts.
3. Because the max bolus setting determines your bolus insulin limit, a Max Bolus alert appears any time you go to the screen to change the value. To continue to the Max Bolus screen, select Continue. 4. Select Max Bolus, and then set the maximum number of insulin units your pump can deliver in one bolus. 5. Select Save. ■ Example 1: Max bolus 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.
Bolus speed The Bolus Speed setting sets the rate at which your pump delivers bolus insulin. You can set a Standard rate (1.5 units per minute), or a Quick rate (15 units per minute). To set your bolus speed: 1. Press and go to the Bolus Speed screen. Options > Delivery Settings > Bolus Speed 2. Select Standard or Quick. 3. Select Save.
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. ■ BG Target Bolus Your insulin sensitivity factor is the amount that BG is reduced by one unit of insulin. The Bolus Wizard feature calculates your estimated bolus based on your BG target range.
Options > Delivery Settings > Bolus Estimate Setup The Bolus Estimate Setup screen appears with the Bolus Wizard feature turned off. 2. Select Bolus Wizard to turn on the feature. If this is the first time you have turned on the Bolus Wizard feature, your pump displays information about the settings you need to enter.
