In the following chapter you will learn how to program all your individual settings for the bolus advice calculation and how to use Bolus Advice in your day-to-day life. 2.1 About Bolus Advice The Bolus Advice function of your meter provides you with bolus recommendations based on your: ·· Current bG test result ·· Expected food intake ·· Current health or activity ·· Individual settings, such as Carb Ratio, Insulin Sensitivity, and other settings that will be explained later in this chapter. When you have programmed these settings, you will only need to: ·· Measure your bG level ·· Enter the amount of carbs you are currently planning to eat ·· Enter your current health or activity state Your meter will then calculate the required amount of insulin based on your personal settings. You can adjust the calculated dose as appropriate. After confirmation, administer the insulin using your pen or syringe. If you are interested in details of the calculation for the recommended bolus, please refer to Appendix A, B, and C. 9 2.2 Setting up Bolus Advice Before you can start setting up the Bolus Advice function, you need to discuss the required setting parameters with your healthcare professional. The following settings are necessary: Time Block settings j Time Blocks … split the day into periods, to facilitate the programming of those settings that change throughout the day, such as Insulin Sensitivity and Carb Ratio. You only need to set the endtime of a Time Block, as this is also the starting time of the following Time Block. Five Time Blocks are set up by default, but you can set up up to eight if necessary. The following parameters can be set up separately for each Time Block. Target Range … is the range of your blood glucose, consisting of a lower and an upper bG value that is considered to be acceptable as long as you are fasting (in the morning or before a meal). The target bG will be calculated automatically as the average between the upper and lower bG values. j 10 Getting bolus advice from your meter j Carb Ratio … is the amount of insulin you need for one unit of carbohydrates. You must program the Carb Ratio for each Time Block you wish to set up. j Insulin Sensitivity … is the amount of insulin you need to lower your bG level by a given amount. You may know this as the “correction factor”. You must program this for each Time Block you wish to set up. Health Event settings j Health Events … are percentages that allow you to adjust the calculated insulin amount to allow for individual needs and health status; for example, when you are planning physical activity (subtract percentages) or you are ill (add percentages). You can set percentages for: ·· Exercise 1 ·· Exercise 2 ·· Stress ·· Illness ·· Premenstrual You cannot adjust Fasting. 11 Advice Option settings j Meal Rise … is an increase in your bG level that is acceptable after a meal. After a meal, the Meal Rise is added to your bG target. After a meal, the bG target value plus the Meal rise value is accepted without a correction bolus, as long as Acting time and Offset time are effective (see the explanations below). Snack Size … is the amount of carbohydrates that is not to be counted as a regular meal. A bolus will be recommended but no Meal Rise is triggered. Acting Time … is the time during which a bolus is effective. The Acting Time starts afresh for each new bolus. Offset Time … is the expected time taken for your bG level to fall after you inject a bolus. The Offset Time starts afresh for each new bolus. j j j 12 Getting bolus advice from your meter 13 1 Press + until the meter powers up.

Your meter automatically stores up to 1000 diary records with their time and date. You can review up to 250 diary records on your meter, or up to 1000 diary records using compatible software. These records are stored from the newest to the oldest. It is very important to set the correct time and date, to ensure that you and your healthcare professional can accurately interpret your blood glucose results and that the bolus advice uses the appropriate settings of the current time block. Each diary record can contain: ·· Date and time ·· bG test result ·· Meal time (events) ·· Carbs ·· Health Event ·· Bolus amount You can display filtered or sorted diary data in graphical or table format. Your meter generates reports, such as bG averages with standard deviations, for the time period you choose (for example, the past 7 days or the past 30 days). Graphs can be a good way to view your bG results. Your meter can display a line graph to depict bG record trends, a graph showing result ranges for daily or weekly, and a pie chart with different colours to illustrate the amount of test results within, above, or below your bG Target Range. 39 The following table depicts the icons used to display your data: Date of Record(s) Time of bG Test bG Icon View Data 20:06 17:33 16:06 13:52 10:02 Back 1 Feb 08 mmol /L 3.8 7.0 8.6 3.3 5.9 Select View bG Value Bolus Icon Health Event Icon Meal Time Icon Carbs Icon Icon 40 Icon Name Description bG Test ·· Icon is displayed when information exists for this diary record regarding a blood glucose test.

Offset Time Prevention of double dosage and after a high bG test result after a correction bolus. 84 Acting Time Appendix Appendix B: Bolus Advice Calculations In this section you will learn how Bolus Advice recommendations are calculated. To make sure that the recommendations meet your needs, you must give the Bolus Advice feature on your meter some extra information, as well as the basic blood glucose (bG) and carbohydrate values. As a safety measure, Bolus Advice will not work without this information. Your healthcare professional will give you the information that you need for the Bolus Advice feature. Carbohydrate Units Choosing how your carbohydrates will be measured is important. In this way, Bolus Advice can give you an accurate result. You just select what carbohydrate units Bolus Advice will use to make its calculations. You can choose between: ·· Grams ·· BE (≈ 12 g) ·· KE (≈ 10 g) ·· CC (≈ 15 g) 85 Time Blocks Your insulin needs may vary depending on the time of day, so using the same values and factors throughout the day would probably not suit your metabolism or lifestyle. This could also lead to incorrect doses of insulin. Start 0:00 5:30 11:00 17:00 21:30 Back Time Blocks End 5:30 11:00 17:00 21:30 0:00 The screen above shows the Time Blocks feature within Bolus Advice. Time Blocks consider your time dependent requirements when calculating your insulin dose at different times of the day. You can program up to eight Time Blocks, depending on your lifestyle. For example, your insulin needs in the morning or evening may not be the same as those in the afternoon or at night, so you can program these different periods as Time Blocks. There are no pre-defined Time Blocks that you should follow. You can choose when a Time Block ends to suit your lifestyle. 86 Appendix Within Time Blocks you will find the following settings: Time Blocks Target Range 4.0 mmol/L 8.0 mmol/L Carb Ratio 10 g 1 U for Insulin Sensitivity 1 U for 2.2 mmol/L Save Cancel Target Range Your bG results should be between the lower and upper values of the Target Range as long as you are fasting (in the morning or before a meal). The target bG will be calculated automatically as the average between the upper and lower bG values. Carb Ratio The Carb (carbohydrate) Ratio defines how much insulin is needed to compensate for a certain amount of carbohydrates. Insulin Sensitivity The Insulin Sensitivity (correction factor) shows how sensitive you are to a dose of insulin. This is how much your bG drops in response to a certain amount of insulin. You can define all of these values separately for each Time Block. The Bolus Advice calculation automatically takes these values into account for the time of day. 87 If your bG level is … … the Bolus calculation is hyper Without a meal – that means, when you do not enter Carbs – these are the Calculations (bG – Target bG) × Insulin Sensitivity Additional recommendation to measure BG more frequently and check for ketones. above Hyper Warning hypo between Upper Target (bG – Target bG) × Insulin Sensitivity.

Note that correction bolus is negative. below Hypo Warning Hypo Warning! Recommendation to eat fast acting carbs. Bolus Advice function not accessible! 89 Health Events If your routine was always the same from one day to the next, then Time Blocks would provide enough information to calculate the correct boluses. However, sometimes your daily routine may be different and your insulin needs will then change. Health Events Exercise 1 Exercise 2 Stress Illness Premenstrual Cancel -10% -20% 0% +20% 0% Save You can use Health Events to take into account various activities or events that increase or decrease your insulin needs. You can choose different Health Events depending on how you are feeling or what you are doing. For example, sport or physical activity could decrease your insulin needs, whereas illness or the menstrual cycle could increase your insulin needs. Many of these activities or events do not occur at regular intervals, and Time Blocks cannot take them into account. With Health Events, you can program how much extra insulin (as a percentage of your usual bolus) you may need. For example, when exercising, your insulin requirement may be 25 % lower. You and your healthcare professional should discuss what percentage to program for each Health Event. 90 Appendix When one of the programmed Health Events occurs in your daily life, you can choose the Health Event on your meter so that Bolus Advice can calculate the correct insulin dose. You can program five different Health Events: ·· Exercise 1 ·· Exercise 2 ·· Stress ·· Illness ·· Premenstrual The Bolus Advice screen and the bG Result screen call these Health with the -icon. Within Health on the Bolus Advice and bG Result screen you can also select Fasting. However, you cannot adjust Fasting by percentage and it does not scale advice calculations. Advice Options – Meal Rise, Snack Size, Acting Time, and Offset Time Advice Options help to make sure that Bolus Advice does not recommend a second bolus for a blood sugar event, such as a meal or a high bG level, that has already been covered by a previous bolus. Start 0:00 5:30 11:00 17:00 21:30 Back Time Blocks End 5:30 11:00 17:00 21:30 0:00 91 Meal Rise After a meal, bG levels usually increase by a noticeable amount, even in people without diabetes. Depending on the type of meal, your bG can reach a maximum about an hour after your meal and return to its original level after another one to two hours. This is a normal process, so Bolus Advice takes this into account using Meal Rise. bG level Acting Time hyper Offset Time Meal Rise Target Value Target Range hypo Current bG values Time Meal Bolus Bolus not required Currently allowed bG value: Meal Rise Fig. 1: Meal Rise The dotted line shows how your bG level typically changes after a meal bolus. Bolus Advice tolerates an increased bG level within the Meal Rise range (green) without calculating an extra correction bolus. Each time you tell Bolus Advice that you have consumed more carbohydrates than the Snack Size, the Meal Rise entry is added to the bG target value. How long the Meal Rise lasts (the width of the green area) is determined by the Offset Time and the Acting Time. 92 Appendix Snack Size The Snack Size defines a certain amount of carbohydrates for which a meal bolus is calculated, but no Meal Rise is triggered. No bG level above the Target Range or currently allowed bG is tolerated for this amount of carbohydrates, so Bolus Advice will calculate a correction bolus for any increase in bG after a snack. Acting Time The Acting Time is the time for which the insulin delivered as a bolus is still effective. It is the whole time for which an increase in bG after a meal bolus or a correction bolus is taken into account. Bolus Advice will not recommend a correction bolus for this time if your current bG level is less than the bG level covered by the previous bolus (Meal Rise or a corrected high bG). To choose the correct value for the Acting Time, you and your healthcare professional should think about the following: ·· Whether you use rapid-acting insulin analogue or fast-acting regular human insulin (the Acting Time should be longer for regular insulin) ·· Your average bolus amount (the larger your average bolus amount, the longer the Acting Time should be) You can program the Acting Time from 1½ to 8 hours. 93 Offset Time The Offset Time is the time taken for the bolus to take effect. After the Offset Time, your bG level should decrease because of the insulin, and at the end of the Acting Time it should return to the target level. The Offset Time must be at least 45 minutes, and the maximum value will be limited by the Acting Time that you choose. 94 Appendix Example The following example explains the effect of the Offset Time and Acting Time: bG level hyper Target Value Target Range hypo Current bG values Bolus Fig. 2: Example blood-sugar curve (bG-level) You calculate and administer a correction bolus at 12 o’clock. The insulin needs time to become effective, so your bG value (dotted line) may not be significantly reduced, even by 2 o’clock. (If you had not administered the correction bolus, your bG might even have increased.) You measure your bG at 2 o’clock and it is nearly the same as at 12 o’clock. Between 2 o’clock and 4 o’clock the effect of the correction bolus, which is still active, will decrease your bG level to a value within the Target Range. 95 hyper Target Value Target Range hypo Current bG values Potential bG level Bolus Fig. 3: Example blood-sugar curve – double dosage However, at 2 o’clock, if Bolus Advice took only your current bG value into consideration, it would ignore the ongoing effect of your correction bolus. It would then recommend an additional bolus to compensate for the raised bG value. Where the effect of the two boluses overlap it could lead to a hypoglycemia (red line), because you would have had two boluses for the same blood-sugar excursion. Therefore, Bolus Advice always compares your bG result with the currently allowed bG value, and not just with the target value for the current Time Block. 96 Appendix The currently allowed bG value considers the following factors: ·· The upper limit of the Target Range for your current Time Block ·· Excursions beyond the Target Value that have had a correction bolus that is still active (Acting Time) ·· bG values that were tolerated as a Meal Rise and which have had a meal bolus that is still active (Acting Time) ·· The expected reduction of your bG level due to the effect of insulin during the Acting Time (the decrease between the end of Offset Time and end of Acting Time) 97 Acting Time bG level hyper Offset Time Corrected bG Target Value Target Range hypo Current bG values Time Bolus Bolus not required Currently allowed bG value: corrected bG Fig. 4: Corrected high bG The above diagram shows an example of the effect of this rule. The first correction bolus at 12 o’clock remains active during the Acting Time (the width of the blue area). If a measured value at 2 o’clock falls within the currently allowed bG value (height of the blue area), no new correction bolus is calculated. 98 Appendix bG level hyper Target Value Target Range hypo Current bG values Bolus Fig. 5: Subsequent boluses Where the measured value is greater than the currently allowed bG value, the newly calculated bolus (light-blue) only considers the difference between the current bG value (dotted line) and the currently allowed bG value (the height of the blue area). During the Acting Time of the first correction bolus (the width of the blue area), only the currently allowed bG value is used to calculate the second bolus. 99 Acting Time bG level hyper Offset Time Meal Rise Target Value Target Range hypo Current bG values Time Meal Bolus Bolus not required Currently allowed bG value: Meal Rise Fig. 6: Subsequent meal boluses Subsequent meals If you eat several meals in a row, the Meal Rise will not add up, but start afresh for each new meal bolus. 100 Appendix Appendix C The Mathematical Basis for Bolus Calculations Below is a list of the most important formulas and principles that Bolus Advice uses to calculate your bolus. It is difficult to accurately calculate a bolus yourself using these formulas (remembering to include the Acting Time and Offset Time of your most recent boluses). This is why Bolus Advice is so useful. It will save you a lot of time and avoids the risk of mistakes in your calculations. Carbohydrates This calculation is required when the bG result falls below the Hypo Warning Limit. It is based on the other values defined for the current Time Block, and the result recommends how much carbohydrate you should consume. The words written in orange in the formula refer to the setting that you find on the meter screen. Carbohydrates = ( Target Range mean value – Current bG) × according to block definition Insulin D bG from Insulin Sensitivity × Carbohydrates Insulin from Carb Ratio Meal bolus Meal bolus = Carbohydrate intake × Insulin Carbohydrates from Carb Ratio 101 Currently Allowed bG Value The currently allowed bG Value considers all blood sugar excursions, that have already been treated by a meal- and/or correction- bolus. For all bG test results below the currently allowed bG value no correction will be recommended. The currently allowed bG value is calculated as follows: Currently allowed = Target Range mean value + Meal rise + according to block definition ∑ blood glucose range covered by correction bolus currently acting correction boluses When no Meal Rise or correction bolus Acting Time is in effect, the value for these in the formula is 0. Correction Bolus Generally, a correction bolus is only calculated if your current bG value is above the hypo bG warning limit and outside of the Target Range. Additionally, it must be above the currently allowed bG value. Only correction boluses greater than 0 will trigger an Acting Time. Correction bolus = (current bG – currently allowed bG) × Insulin D bG from Insulin Sensitivity The size of the correction bolus depends on the following: ·· If your bG is higher than the currently allowed bG, then: Correction bolus = (current bG – currently allowed bG value) × Insulin Sensitivity ·· If the current bG is higher than the Hypo Warning Limit, and the current bG is lower than Target Range lower limit, then the correction bolus that is subtracted from the meal bolus is: Correction bolus = (current bG – Target Range average value) × Insulin Sensitivity 102 Appendix Correction Bolus with Carbohydrate Intake Whenever you tell Bolus Advice that you have consumed carbohydrates, the related meal bolus is always offset against any correction bolus (even negative). When you eat a meal, Bolus Advice also calculates the correction bolus for bG results that are within the Target Range; more specifically, if your current bG result is below the Target Range average value, or if your current bG is above the currently allowed bG value. Boluses that are calculated to be less than 0 are just displayed as 0. 103 Changing your Meter Settings 1. From main menu press x or z to move to Settings. 2. Press = to enter.
