Setting up Continuous GlucoseMonitoringThis chapter explains how to wirelessly connect your pump and transmitter, andhow to enter your sensor settings and set up continuous glucose monitoring(CGM) on your pump. You will need the following:• MiniMed 640G insulin pump• Sensor glucose settings (provided by your healthcare professional)• Enlite sensor• Guardian 2 Link transmitter kitWARNING: Do not make therapy treatment decisions based onsensor glucose values because sensor glucose and blood glucosevalues may differ. If your sensor glucose reading is low or high, or ifyou feel symptoms of low or high glucose, confirm your bloodglucose with your BG meter prior to making therapy decisions toavoid severe low or high glucose conditions.Understanding Continuous Glucose Monitoring (CGM)The Sensor feature on the pump lets you integrate and use continuous glucosemonitoring (CGM). CGM is a sensor glucose monitoring tool that uses a glucosesensor that is placed below your skin to continuously measure the amount ofglucose in your interstitial fluid. CGM helps you better manage your diabetes by:• Recording your glucose values throughout the day and night Setting up Continuous Glucose Monitoring 151■ setting up continuous glucose monitoringMP6025958-022 / ARELEASED

For detailson low alerts and suspend options, see Low settings, on page 157.High settingsThese settings alert you if your sensor glucose:• is rising rapidly (Rise Alert)• is approaching your high limit (Alert before high)• has reached your high limit (Alert on high)The following table describes the High Settings.High glucosesettingDescriptionHigh limit Your high limit is the value on which your other high settings arebased. Your high limit can be set from 100 mg/dL to 400 mg/dL. Youcan set up to eight high limits for different time segments throughoutthe day or night.Alert beforehighWhen Alert before high is on, you will receive an alert any time thesensor glucose is predicted to reach the high limit. This makes youaware of potential highs before they occur.Time beforehighTime before high is only available when using Alert before high. Timebefore high determines when you will receive an Alert before high.You can set a time between 5 and 30 minutes.Alert on high When Alert on high is on, your system alerts you when your SGreading reaches or exceeds your High Limit.156 Chapter 10MP6025958-022 / ARELEASED
High glucosesettingDescriptionRise Alert The Rise Alert notifies you when your glucose is rising rapidly. Thisalert helps you understand how much your glucose levels are affectedby meals or, for example, when forgetting to give a bolus.Rise Limit The Rise Limit determines when you will receive a Rise Alert. Rise Limitis only available when using Rise Alert.To set up your high settings, see Setting up the High Settings, on page 167.Low settingsThe low settings allow you to be alerted and/or have insulin delivery suspendedwhen you are either approaching or have reached your low limit. This is done byusing alerts and the SmartGuard feature described on page 152.The following graph shows the different low settings you can use:Low LimitAlert before lowAlert on lowSuspend before lowSuspend on lowWARNING: SmartGuard suspend by sensor features are notintended to be a treatment for low blood glucose. Having insulinsuspended when glucose is low may not bring your blood glucoseback to your target range for several hours. Always confirm yourblood glucose readings with your BG meter and treat according tothe recommendations of your healthcare professional.The following sections describe the SmartGuard feature and the low settings. Fordetails on setting up SmartGuard and your low settings, see Setting up the LowSettings, on page 171.■ setting up continuous glucose monitoring Setting up Continuous Glucose Monitoring 157MP6025958-022 / ARELEASED
Low limitThe low limit is the value on which the other low settings are based. The low limitcan be set from 50 mg/dL to 90 mg/dL. You can set up to eight low limits fordifferent periods of the day or night.Suspend before lowThe Suspend before low feature stops insulin delivery when your sensor glucosevalues are approaching your low limit. This feature is intended to suspend insulindelivery to minimize the amount of time spent low.The default setting for the Suspend before low feature is off. Consult yourhealthcare professional for the Suspend before low setting that is best for you.If you turn on Suspend before low, then Alert on low is automatically turned on.You also have the option to turn on Alert before low.•If Alert before low is on, your pump alerts you when insulin delivery issuspended. For details, see Alert before low, on page 160.• If Alert before low is off, then Suspend before low appears on the screen, butthe pump will not beep or vibrate when insulin delivery is suspended.WARNING: The Suspend before low feature uses the sensor glucosevalue, not your blood glucose value to automatically suspendinsulin delivery. Your pump automatically suspends insulin deliverywhen your sensor glucose is approaching the low limit. Howeveryour blood glucose reading may be higher than the sensor glucosevalue. This could result in hyperglycemia. Likewise, your pump maynot suspend insulin delivery because your sensor glucose is notapproaching the low limit. However, your blood glucose may belower than the sensor glucose value. This could result inhypoglycemia. Always check your blood glucose and treat asappropriate.Suspend before low conditionsWhen a Suspend before low event occurs, all insulin delivery is suspended. For aSuspend before low event to occur, both of these must happen:• Your SG value is at or within 70 mg/dL above your low limit.158 Chapter 10MP6025958-022 / ARELEASED
• Your SG is predicted to reach or fall below a level that is 20 mg/dL aboveyour low limit within approximately 30 minutes.Responding to a Suspend before low eventWhen you clear the Suspend before low alert, the SmartGuard suspend by sensoricon flashes and "Suspended before low" appears on your Home screen. If yourSG reaches your low limit, an Alert on low occurs.When a Suspend before low event occurs, insulin delivery will remain suspendedfor at least 30 minutes, unless you manually resume your basal delivery. For details,see Manually resuming basal delivery during a suspend by sensor event, on page 174.After the minimum 30-minute suspend time, basal insulin delivery willautomatically resume if the following conditions are met:• Your SG is at least 20 mg/dL above your low limit.• Your SG is estimated to be more than 40 mg/dL above your low limit within30 minutes.Your basal insulin delivery will be suspended for a maximum of two hours, unlessthese criteria are met during the suspend or unless you manually resume yourbasal insulin. For details, see Manually resuming basal delivery during a suspend bysensor event, on page 174.If you do not respond to the Suspend before low alert, your pump resumes insulindelivery after two hours and displays a Basal delivery resumed alert.When Suspend before low is unavailableAfter a Suspend before low event occurs, there is a period of time when theSuspend before low functionality is unavailable. This time will vary depending onwhether or not you respond to the Suspend before low event. You can manuallysuspend your insulin delivery at any time. For details, see Stopping and resumingyour insulin delivery, on page 54.Note: The maximum amount of time the Suspend before low featurewill be unavailable is four hours. When the SmartGuard suspend by sensor features are unavailable, the SmartGuardsuspend by sensor icon on the Home screen appears gray .■ setting up continuous glucose monitoring Setting up Continuous Glucose Monitoring 159MP6025958-022 / ARELEASED
When a Suspend before low event occurs and you respond within two hoursand:• Stay suspended for the two hour maximum suspend time, the SmartGuardsuspend by sensor features will be unavailable for 30 minutes after your basalinsulin delivery resumes.• Your insulin automatically resumes due to your rising SG levels, theSmartGuard suspend by sensor features will be unavailable for 30 minutesafter your basal insulin delivery resumes.• Manually resume your basal insulin delivery, the SmartGuard suspend bysensor features will be unavailable for 30 minutes after your basal insulindelivery resumes.If your pump has been suspended for two hours and you have not responded,basal insulin delivery automatically resumes.If you respond within 30 minutes of basal insulin delivery being resumed, theSmartGuard suspend by sensor features will be unavailable for a total of 30minutes. For example:• If you respond 10 minutes after your basal insulin delivery resumes, theSmartGuard suspend by sensor features will be unavailable for an additional20 minutes.• If you respond 20 minutes after your basal insulin delivery resumes, theSmartGuard suspend by sensor features will be unavailable for an additional10 minutes.If you respond 30 minutes to four hours after your basal insulin delivery resumes,the SmartGuard suspend by sensor features will be available immediately.If you do not respond, the SmartGuard suspend by sensor features will beunavailable for four hours after basal delivery resumes.Alert before lowWhen Alert before low is on, you will receive an alert when you are approachingyour low limit. This makes you aware of potential lows before they occur.The Alert before low feature can be used with the Suspend before low andSuspend on low features. The Alert before low feature works as follows:160 Chapter 10MP6025958-022 / ARELEASED
• if Alert before low is on, and both suspend by sensor features are off, youreceive the Alert before low 30 minutes before you reach your low limit.• If Suspend on low is on, and Alert before low is on, you receive an Alertbefore low 30 minutes before you reach your low limit.• If Suspend before low is on, and Alert before low is on, you receive a Suspendbefore low alert when insulin delivery is suspended. For details, see Suspendbefore low, on page 158.You can also choose to have the Alert before low off.Suspend on lowThe Suspend on low feature stops insulin delivery when your sensor glucose valuereaches or falls below the low limit that you set. When a Suspend on low eventoccurs, all insulin delivery is suspended. This feature is used for situations whenyou cannot respond to a low glucose condition. It is intended to suspend insulindelivery and minimize the amount of time spent low.The default setting for the Suspend on low feature is off. Consult your healthcareprofessional for the Suspend on low setting that is best for you.If you turn on Suspend on low, then Alert on low is turned on automatically. Formore information, see Alert on low, on page 163.WARNING: The Suspend on low feature uses the sensor glucosevalue, not your blood glucose value, to automatically suspend yourpump. Your pump may automatically suspend when your sensorglucose is at or below the low limit, while your blood glucose isabove that limit. This could result in hyperglycemia. Likewise, yourpump may not suspend even though your blood glucose is at orbelow the low limit. This could result in hypoglycemia. Alwayscheck your blood glucose and treat as appropriate.Responding to a Suspend on low eventWhen you clear the Suspend on low alarm, the SmartGuard suspend by sensoricon flashes and "Suspended on low" appears on your Home screen.When a Suspend on low event occurs, the pump alerts you.■ setting up continuous glucose monitoring Setting up Continuous Glucose Monitoring 161MP6025958-022 / ARELEASED

If the Resume basal alert is off, basal insulin resumes, butyou do not receive an alert. However, you will get a message indicating that thebasal has automatically resumed.If basal resumes after the maximum suspend time of two hours, you will be alertedeven if the Resume basal alert is set to off. It is important that you check your BGand ensure your glucose is at a safe level.For details on setting up the Resume basal alert, see Setting up the Low Settings, onpage 171.SmartGuard suspend by sensor examplesThe following examples describe several scenarios that illustrate different types ofsuspend events, user actions in response to these events, and what happens toinsulin delivery in each case.Example 1: Suspend before low, non-responsive, auto resume basal(trending upwards)Sarah has been experiencing low sensor glucose values. Her healthcareprofessional has recommended she use the Suspend before low feature. While at aconcert, Sarah’s sensor glucose values are approaching her low limit. Her pumprecognizes that her glucose will be at or within 20 mg/dL above her low limitwithin 30 minutes and suspends her insulin. Sarah has her Alert before low set tooff so that she is not alerted when this occurs.164 Chapter 10MP6025958-022 / ARELEASED
Low Limit20 above Low Limit70 above Low Limit30 minSTOPAn hour later, her sensor glucose values are 21 mg/dL above her low limit. Herpump estimates her sensor glucose values will be 45 mg/dL above her low limitwithin 30 minutes. Her pump automatically resumes her basal insulin delivery.When the concert ends, Sarah sees that her pump automatically suspended andresumed her insulin delivery and a potential low was avoided. She clears themessages by selecting OK.Example 2: Suspend before low, responsive, manually resume basalKate decides to meet her friends at the mall. While shopping, she gets a Suspendbefore low alert. This indicates that her sensor glucose values are approaching thelow limit she has set. She clears the alert and sees that her insulin has beensuspended. Kate checks her BG to confirm. Based on her healthcare professional'srecommendation, Kate stops for a snack to help avoid hypoglycemia. Knowing thecarbohydrate will make her glucose rise, Kate manually resumes her basal insulindelivery by selecting Suspended before low from the Home screen and choosingResume basal.Kate knows that after she has manually resumed her basal insulin delivery, thesuspend functions will be unavailable for 30 minutes. However, she will be alertedif she reaches her low limit.■ setting up continuous glucose monitoring Setting up Continuous Glucose Monitoring 165MP6025958-022 / ARELEASED
Example 3: Suspend before low, responsive, stays suspendedDoug has just finished his evening jog on the beach. As he is walking home, hereceives a Suspend before low alert. He sees that his pump has automaticallysuspended his insulin delivery. Doug clears the alert by selecting OK on his pump.He knows that his pump is now suspended and insulin delivery has been stopped.He checks his BG to confirm and keeps his insulin suspended.A while later, Doug receives another alert. He looks at his pump and sees that hehas received an Alert on low. His SG has reached his low limit. He clears the alertand checks his BG to confirm. He eats carbohydrates to treat the low glucose asinstructed by his healthcare professional.Doug keeps his insulin suspended as directed by his healthcare professional. Heknows that once his SG is above his low limit and trending upward, or reaches themaximum suspend time of two hours, basal insulin delivery will automaticallyresume.Example 4: Suspend on low, response after basal delivery resumesMichael is on his college hockey team. He played in a hockey tournament all dayand is so exhausted that he falls asleep watching television. His sensor glucosevalue begins to drop. When his sensor glucose value reaches his low limit, thepump begins to alarm. It automatically suspends all insulin delivery. Michael doesnot respond to the alarm. After ten minutes, his pump begins to siren and displaysthe emergency message.About three hours later, Michael’s roommate comes home. He hears the pumpsirening and wakes up Michael. Michael clears any messages by selecting OK. Hesees that his basal insulin was suspended for the two hour maximum and hadautomatically been resumed. He checks his blood sugar and sees that it is withinthe target range.166 Chapter 10MP6025958-022 / ARELEASED
