Now you are familiar with how to use this user guide and where to go for help. Throughout the user guide you’ll see color-coded boxes containing Safety Statements. The next chapter, Indications for Use and Safety Statement, lists all Safety Statements along with how to read and interpret them.
Chapter 2 Getting Started: Indications for Use and Safety Statement 2.1 Introduction We want the G5 Mobile System to be a valuable tool in your diabetes management. Like any system, there are steps to take to get the most out of it.
Let’s start with definitions. Then we’ll look at a Safety Statement example used throughout the user guide, and then review the Safety Statements broken down into the system’s components. Safety Statement A Safety Statement is a brief statement of the system’s indications, contraindications (when to avoid using it), relevant warnings, and precautions.
o Lists only those statements applicable to that specific chapter Chapter’s Safety Statements Each chapter will list all applicable indications, contraindications, precautions, and warnings. Some chapters will have multiple Safety Statements; others have none. Safety Statements are located toward the beginning so you can keep them in mind as you learn about that chapter’s topic. The same statement may be repeated throughout the user guide.
The following is an example of a chapter’s Safety Statement and how to read it. Warning Do: Calibrate at least once every 12 hours Why: Calibrating less often than every 12 hours might cause inaccurate sensor glucose readings Consequences: Missing severe low (hypoglycemia ) or high (hyperglycemia) Alarm or Alerts Since this is a Warning, you know it covers important safety information. Italics are the Do/Don’t steps to follow: Calibrate at least once every 12 hours.
What are the system indications? Well, in technical terms, the indications are: The Dexcom G5 Mobile Continuous Glucose Monitoring (CGM) System is a glucose monitoring system indicated for detecting trends and tracking patterns in persons (age 2 years and older) with diabetes. The system is intended for single patient use and requires a prescription. The system is indicated for use as an adjunctive device to complement, not replace, information obtained from standard home glucose monitoring devices.
The system’s trend and pattern information is based on a series of sensor glucose readings taken over a period of time. Work with your healthcare professional and create a game plan on how to best use your trend and pattern information in managing your diabetes. Contraindications Contraindications let you know when not to use the system; you may hurt yourself or damage the system. Remember, if used during certain situations, the risk of use may clearly outweigh any potential benefit.
Review Training Materials Thoroughly review the training materials included with your system before using. Incorrect use could lead you to misunderstand system information or might affect its performance and you might miss a severe low or high glucose event. Treatment Decisions The system does not replace your BG meter. When making treatment decisions, such as the amount of insulin you need, only use your BG value.
are—you have to teach your system what a given BG value is by entering in a KNOWN glucose value from your BG meter. Warning Calibrate on Schedule Calibrate at least once every 12 hours. Calibrating less often than every 12 hours might cause sensor glucose readings to be inaccurate, resulting in you missing a severe low or high glucose event. Precautions Be Accurate, Be Quick Enter the exact BG value displayed on your BG meter within five minutes of a fingerstick.
Calibrating during a significant rise/fall of your BG may affect accuracy of sensor glucose readings, resulting in you missing a severe low or high glucose event. Fingerstick Only Only use fingerstick measurements from your BG meter for calibration. Alternative site BG values from your arms, palm of your hand, etc., may be different and less accurate than your fingerstick BG values.
If a sensor wire breaks under the skin with no portion of it visible, don’t remove it. Contact your healthcare professional if you have redness, swelling, or pain at the insertion site. Placement Do not insert the sensor component of the system in a site other than the belly/abdomen (ages 2 years and older) or the upper buttocks (ages 2 to 17 years). The placement and insertion of the system sensor is not approved for other sites.
Before opening the sensor package, wash your hands with soap and water, then dry. If your hands are dirty while inserting the sensor, you may contaminate the insertion site and get an infection. Before sensor insertion, clean the skin with alcohol wipes to prevent infections. Don’t insert the sensor until the cleaned insertion site is dry, and free from any lotions or perfumes.
When ending a session, don’t throw away the transmitter. The transmitter is reusable and can be used in multiple sensor sessions. Keep using it until the system notifies you the transmitter battery is about to expire. Don’t Share Your Transmitter Never share your transmitter with another person. The system is a prescription-only medical device and is meant, or indicated, for your use only. Your transmitter is tied to your readings. If used by someone else, your reports, Alarm and Alerts, etc.
• Rising more than 3 mg/dL each minute • Falling 2-3 mg/dL each minute • Falling more than 3 mg/dL each minute Airport Scanners Be aware of airport body scanners and baggage x-rays when you travel. Do not place any part of the system in the baggage x-ray machine or body scanner. Ask for visual inspection instead: • Baggage x-ray machine: Instead of putting any part of your system through the baggage x-ray, ask the TSA officer to visually inspect it.
more than 20 feet from each other or are separated by an obstruction, they might not communicate, resulting in you missing a severe low or high glucose event. As with any wireless device, water is often the biggest culprit in reducing communication distance. This applies to the transmitter and display devices. Take special care when swimming, getting into a pool, bathtub, shower, etc.
2. Verify app hasn’t been shut down. 3. Turn on Bluetooth. 4. Turn off Do Not Disturb (if available on your smart device). 5. Restart app after device is restarted. 6. Set Volume at a level you can hear. 7. Do not close app; always run app in the background. 8. Make sure accessory devices do not override your smart device settings. If your settings are incorrect, you might miss a severe low or high glucose event. App Alarm/Alert vibrations aren’t any different from other vibrating apps on your smart device.
Use USB cable only as directed and store safely. Misuse of the USB cable can present a strangulation risk. Precautions Test Receiver Shortly after the receiver is powered on or plugged in to charge, it should briefly vibrate and beep. If this doesn’t happen, it may mean the vibration motor and/or speaker are not functioning properly. Please retry. If it still doesn’t vibrate and beep, contact Technical Support. If your receiver gets wet or dropped, make sure the speaker and vibrations still work.
• Provide an overview of Safety Statements by category What’s Next? In our next chapter, you will learn about the risks and benefits of using the system.
Chapter 3 Getting Started: Risks and Benefits When using any medical device, there are risks and benefits. In this chapter, you’ll learn what they are, so you can better understand the pros and cons of CGM and the G5 Mobile System. First, let’s review some possible risks. 3.1 Risks There are some risks with using real-time CGM. Not Receiving Alarm/Alerts If you aren’t getting your CGM Alarm/Alerts, you run the risk of not knowing you are having a severe glucose low or high.
If the sensor’s glucose reading is higher than your meter’s BG value, you may miss a Low Alert. As an example, your last sensor glucose reading was 82 mg/dL, whereas your BG value shows 78 mg/dL. If your Low Alert is set at 80 mg/dL, you won’t receive an Alert because the sensor glucose reading is 82 mg/dL. If you’re not receiving an Alarm/Alert, and not taking fingerstick measurements, you may be unaware of low or high glucose levels.
where your glucose is now, where it has been, where it’s heading, and how fast it’s changing. Understanding your trends allows you to take proactive action, helping you avoid dangerously low or high glucose values. Using Dexcom Share (see Part 5) allows friends and family, your Followers, to monitor your glucose activity, adding another layer of support and peace of mind. Helping Your Diabetes Management Wearing the G5 Mobile on a consistent and ongoing basis helps you manage your diabetes.

6.9 Receiver Bluetooth Tips Your transmitter and receiver begin communicating once you start a sensor session. After approximately 30 minutes, if the Bluetooth symbol is solid, and not blinking, your transmitter and receiver are talking to each other. • If blinking, Bluetooth is looking for your transmitter o Make sure your transmitter and receiver are within 20 feet of each other o Don’t start a sensor session until they are paired.
6.10 Sensor Session Warmup The sensor takes about two hours to adjust to your body. While you are in the sensor warmup period, you can customize your settings. Chapter 12 steps you through how to personalize your G5 Mobile’s display devices. Once the sensor warmup is complete, you’re ready to enter your initial calibrations! The next chapter shows you how.
Chapter 7 Let’s G5! The Basics: Calibration 7.1 Introduction In the previous chapter, you learned how to insert your sensor, attach your transmitter, and start a new sensor session. You’re now ready to begin your last step before getting your sensor glucose readings: Calibration. This chapter reviews not just your initial calibration, but also update calibrations required throughout your sensor session.
• • Correctly enter your fingerstick measurement o App o Receiver Identify calibration errors 7.2 Safety Statements Contraindication Don’t: Never take any medications containing acetaminophen during your sensor session. Why: Taking medications with acetaminophen (such as Tylenol or Excedrin Extra Strength) while wearing your sensor may falsely raise sensor glucose readings. Level of sensor inaccuracy: 1. Depends on amount of acetaminophen active in your body. 2. May be different for each person.
Warning Do: Calibrate at least once every 12 hours. Why: Calibrating less often than every 12 hours might cause inaccurate sensor glucose readings. Consequences: Missing severe low (hypoglycemia) or high (hyperglycemia) Alarm or Alerts. Precaution Do: Look at trend arrows before calibrating. Trend arrows help you determine if you can calibrate now or should wait. Don’t: Never calibrate if your BG is changing at a significant rate, typically more than 2 mg/dL per minute.
Precaution Do: Enter the exact BG value displayed on your BG meter within five minutes of a carefully performed fingerstick measurement. Why: Entering the wrong BG values, or waiting more than five minutes before entry, might affect sensor accuracy. Consequences: You may miss a severe low or high glucose event. Precaution Do: Only use fingerstick measurements from your BG meter for calibration. Don’t: Never use alternative site BG values such as blood from palms, forearms, etc.
Calibrations are a must to make sure the CGM system is performing at its best. By calibrating when the system notifies you that a calibration is due, the G5 Mobile uses your meter’s BG value to make sure the sensor glucose readings remain accurate throughout your session. How Do I Calibrate? Take a fingerstick measurement from your meter, and simply enter the meter’s BG value into one display device.
7.4 When to Calibrate Calibrating on a regular schedule aligns your sensor glucose readings with your meter’s BG values. Without calibrations, your sensor may be inaccurate, and as a result, so will your display device’s sensor glucose readings, Alerts, and prompts, etc. There are important times when you must calibrate: 1. Initial or Startup Calibration: two hours after you insert your sensor. 2. 12 Hour Update: every 12 hours after two-hour startup calibration. 3. When system prompts you.
Figure 5. Example Minimum Calibration Schedule During Seven Day Sensor Session Update calibrations are typically 12 hours since your last calibration; however, they can be sooner. As an example, if you know your next calibration is due at 10 PM, but you want to go to bed at 9 PM, you can do the calibration before bedtime, resetting the 12-hour count down. 1. Enter one fingerstick measurement at least every 12 hours. 2. Display devices provide calibration prompts. 3.

Second Calibration Smart Device: Lock Screen Smart Device: In App Receiver Your sensor glucose readings begin in approximately five minutes once the device(s) accepts your calibrations.
Once your startup calibration is done, your update calibration schedule begins. The steps to enter your update calibrations are the same as your initial calibration, including only entering values in one display device. The only difference is, with update calibrations, enter your BG meter value just once. The default BG value is your current reading if available or 120 mg/dL.
In case you can’t look at your screen, both the smart device and receiver provide, with the exception of your regular 12-hour update calibration, beep/vibration prompts to let you know it’s time to calibrate or if there was a system calibration error. For more information on setting your sound/vibration prompts and how to clear them, please see Chapter 9. Smart Device Calibration prompts will alert you with a triple beep if your smart device is not on Silent or Do Not Disturb.
c. Enter exact BG value from your meter for each calibration. Don’t: 1. Don’t take acetaminophen-containing medication during your session (for example, Tylenol). a. See your healthcare professional to better understand how long acetaminophen is active in your body. 2. Don’t calibrate if your BG values are under 40 mg/dL or over 400 mg/dL. a. If BG value is outside of this range, receiver doesn’t understand these values and won’t calibrate. i. You must wait until your BG is in the range to calibrate. 3.

While each display device may have different ways of presenting sensor glucose readings and trends, the meanings are the same. Fingerstick measurements entered into one device will be available in the other approximately ten minutes after entering data.
In the next chapter, you’ll learn how to end a typical seven-day sensor session, what to do if you need to end your sensor session early, along with removing the transmitter and determining if you need to replace it.
Chapter 8 Let’s G5! The Basics: Ending Your Sensor Session and Transmitter Session 8.1 Introduction G5 Mobile sensor sessions last seven days. This chapter reviews what you should expect when your session is about to expire and removing the sensor and transmitter. It also covers how to determine if you need to end your session early.
8.3 Ending Your Sensor Session There are different ways your session might end. The most common is your sensor’s typical seven-day time frame ended. The second is ending the sensor session early. You may end a session early based on a personal decision, or on rare occasions, the receiver or app detects sensor issues and prompts you to end the session. Let’s review ending a normal session first; later in this chapter we’ll review the prompts for ending the session early.
Device What you see What it means Smart Device: Lock Screen Two hours remain on your current sensor session. Smart Device: In App Continue to get sensor glucose readings. Receiver Device What you see What it means At Thirty Minutes Smart Device: Lock Screen Thirty minutes remain. Continue to get sensor glucose readings.

Smart Device: In App Receiver Device What you see What it means Smart Device: Lock Screen Smart Device: In App Wait up to three hours while the system autocorrects. Check transmitter—is it properly inserted into sensor pod? Make sure you haven’t taken acetaminophen.
The G5 Mobile knows when a typical seven-day sensor session is over, automatically ending the session in each display device. However, if you need to end the session early, you need to let the system know by manually stopping the sensor session. While the end result is the same (ending a sensor session), the steps differ between the app and receiver. If you’re using both, no need to stop the sensor session in each: the other display will see the session has stopped.
Step What you see 1 2 What it means What you do Go to Main Menu. Tap Menu. Ends sensor session. During session, Stop Sensor option appears. Tap Stop Sensor. 3 Do you want to stop the sensor? Tap OK . 4 Thinking screen. Wait. Ready to start a new session. Remove sensor. Not in active session, Start Sensor option appears. Tap Start Sensor when ready for new session. 5 Insert new sensor.

Press power button for two seconds to turn the receiver back on. It may take up to 20 seconds for the receiver to turn on. Preventing Sensor Failures Sensor failures can happen when your display device doesn’t receive your sensor’s glucose readings.
Remove Transmitter From Sensor Pod Remember that the transmitter is reusable—do not throw away. It lasts 90 days and can be used in multiple sensor sessions. Keep using it until the system notifies you the transmitter battery is about to expire. Before reusing the transmitter in your new sensor session, remove it from the old sensor pod. You can detach transmitter two ways: 1. Use safety lock (see With Safety Lock table). You removed this from the applicator barrel at the beginning of the session. 2.
Step Picture What you do 3 Grasp sensor pod’s wide end with two hands and place fingers in sides’ open slots. 4 Pull tabs away from transmitter. 8.5 End of Transmitter Battery How do you know if your transmitter’s battery will last through your next session? System messages help you determine if your transmitter’s battery will last through your next seven-day session.

Chapter 9 Next Steps - Getting the Most out of Your G5 Mobile: Home Screen, Rate of Change Arrows, and Errors 9.1 Introduction to Home Screens In the previous chapter, you learned about calibrations: why they are important and how to do them. Within five minutes of entering your two initial calibrations your sensor glucose readings begin! In this chapter, you’ll learn three things.
Take a moment and read the safety statements. If not followed, your sensor glucose readings and trends may be less accurate, and you may miss important High or Low Glucose Alerts. Contraindication Don’t: Never take any medications containing acetaminophen during your sensor session. Why: Taking medications with acetaminophen (such as Tylenol or Excedrin Extra Strength) while wearing sensor may falsely raise sensor glucose readings.
Warning Don’t: Never ignore symptoms of high and low glucose. Do: Measure your BG with a fingerstick measurement if sensor glucose readings don’t match your symptoms. Why: Your sensor glucose readings may not be accurately reading your glucose. Consequences: Using sensor glucose readings for treatment decisions could result in having severe low (hypoglycemia) or high (hyperglycemia) events.

Chapter 10 Next Steps - Getting the Most out of Your G5 Mobile: Daily Events Affect Your Glucose Trends and Patterns 10.1 Introduction Your daily activities can impact your glucose trends and patterns. In the previous chapter, you learned how to read your glucose trend screens; in this chapter, you learn how to enter situations, or “Events”. By tracking Events, you can determine how certain actions or circumstances affect your glucose levels.
An Event is an action or situation affecting your glucose levels. With the G5 Mobile, you have the ability to enter your daily Events, helping you track their effect on your glucose trends. Once entered into the smart device or receiver, Events can be viewed in Dexcom reports. The reports help you review how each Event influenced your glucose trends. You can use the reports with your healthcare professional to create a game plan in managing your diabetes.

But what happens if you’re driving or at the movies and can’t, or don’t want to, keep looking at your display device? The G5 Mobile understands there are times when you can’t look at your receiver or smart device; however, you still need to know critical glucose trends or if you’re not getting your sensor glucose readings.
11.2 Safety Statements The Alarm and Alerts were designed to keep you safe, helping you avoid severe lows and highs or missing your readings. The following safety statements help ensure you get your Alerts and Alarm. Warning Do: Verify your smart device settings let you get Alarm and Alerts. To receive Alarm/Alerts you must: 1. Make sure G5 Mobile app Notifications are turned on in Settings menu. 2. Verify app hasn’t been shut down. 3. Adjust volume so you can hear sounds. 4. Turn Bluetooth on. 5.
Warning Do: Disconnect headphones from your smart device when not in use. Why: If headphones are connected while not being used, you won’t hear an Alarm or Alert. Consequences: Missing severe low or high glucose Alarm or Alerts. Precaution Don’t: Never prevent communication between transmitter and display devices. Do: Keep smart device and receiver within 20 feet of transmitter and away from obstructions.
Precaution Do: Verify smart device and receiver are turned on. Why: Neither the receiver nor smart device will generate sensor glucose readings, Alarm or Alerts if turned off. Consequences: Missing severe low or high glucose Alarm or Alerts. 11.3 Alarm and Alerts As part of managing your diabetes, you learned how to read your Trend screen and how to enter Events. In this chapter, you’ll learn how Alarm and Alerts can keep you safe from severe lows or highs.
Alerts message you with vibrations (vibrations not available on all smart devices), visual prompts, sounds, or a combination of all three. Unlike the Alarm, you can customize your different Alert’s target range (see Chapter 12). During your initial setup, you establish your Low/High Glucose Alert levels. As mentioned before, this chapter is a review of the Alarm and Alerts, recommended smart device settings, and the receiver’s default Alert settings.

check your glucose and make any treatment decisions. Receiver 11.5 App: Alarm/Alert Recommended Settings The receiver is a standalone medical device and used solely to monitor your glucose trends.
The receiver’s Alarm/Alerts are vibrations and a beep, or a series of beeps, based on the Alarm or Alert. Beeps and vibrations are preprogrammed into the receiver, and unlike the smart device, the volume can’t be changed. In Chapter 12 you’ll learn how to adjust the volume and intensity of your Alarm/Alerts. The following is a table of the receiver’s default beep and vibration patterns. If you clear the Alert’s initial vibration, you won’t get any beeps or sounds unless you’ve turned on the Repeat Alert.
Initial Default Alert: Vibrates 3 times. After 5 Minutes: Vibrates/beeps 3 times every 5 minutes until cleared or sensor glucose readings rises above Alert level. Trend screen will continue to reflect Alert until sensor glucose readings go above Alert level. Initial Default Alert: Vibrates 2 times. After 5 Minutes: Vibrates/beeps 2 times every 5 minutes until cleared.or sensor glucose readings go below Alert level.
Initial Default Alert: None/Off. After Setting Change: Vibrates 2 times, 2 sounds. After 5 Minutes: Vibrates/beeps 2 times every 5 minutes until cleared or sensor glucose reading rises rate drops below Alert level. Initial Default Alert: None/Off. After Setting Change: Vibrates 3 times. After 5 Minutes: Vibrates/beeps 3 times every 5 minutes until cleared or sensor glucose reading fall rate rises above Alert level.
Low Repeat/High Repeat What you see Beeps and vibration Initial Default Alert: None/Off. After Setting Change: Vibrates 3 times. After 5 Minutes: Vibrates/beeps 3 times every 5 minutes until cleared or sensor glucose reading rises above Alert level. Will re-alert if sensor glucose readings drop at or below 55 mg/dL. Initial Default Alert: None/Off. After Setting Change: Vibrates 2 times. After 5 Minutes: Vibrates/beeps 2 times every 5 minutes until cleared or sensor glucose reading drops below Alert level.
Initial Default Alert: On. After Setting Change: Vibrates 1 time. After 5 Minutes: Vibrates/beeps 1 time every 5 minutes for a total of 6 times if not cleared. After 6 times it will not alert again. 11.7 Clearing Alarm/Alerts Alerts require you to acknowledge and clear them. How this is done depends on your display device. If using both display devices, you’ll need to clear each separately. Due to its medical importance, the Alarm is more persistent than an Alert.
Tap OK to accept Alarm or Alert. Smart Device: In App Clearing Your Receiver What you see What you do Tap OK. Once an Alert is cleared, you won’t receive the same Alert unless you hit the Alert’s target range again.

Chapter 12 Next Steps - Getting the Most out of Your G5 Mobile: On the Go With G5: Customizing Your Alarm and Alerts 12.1 Introduction The receiver and app come with default glucose Alert level settings, but perhaps they don’t reflect the glucose level that works best for you. Perhaps you’re in a meeting and can only clear an Alert, yet want to make sure your Alert repeats, or continues, until you’re able to take corrective measures.
Warning Do: If using both receiver and app to get an Alarm or Alert, change settings in each display device. Why: Any changes to the G5 Mobile app will not carry over to the receiver. Consequences: Missing severe low or high Alarm or Alerts. 12.3 Changing App Alarm and Alerts App Screen Overview The Alerts Main Menu lists all customizable Alerts and their current settings.

Chapter 17 Everything Else G5: Technical Information 17.1 Device Performance Characteristics NOTE: We recommend that you review the information in this chapter with your healthcare professional to understand how well the G5 Mobile performs. The G5 Mobile (the system) uses a glucose sensor to continuously measure and monitor your glucose levels. The sensor is “calibrated” using a commercially available BG meter. Once calibrated, the system reports glucose readings up to every 5 minutes.
Software 505 Pediatric Study: the receiver included software version SW10505 The G5 Mobile incorporates the algorithm from software version SW10505 and has a new software number. Overview of Adult Studies The system performance for adults was evaluated in two separate prospective clinical studies: Original Adult Study (software SW10050) and the Software 505 Adult Study (software SW10505).
system readings agreed with laboratory standard BG results. The remainder of the study took place at home, and the system performance was also paired with the comparative meter results, referred to as the “SMBG.” Overview of Pediatric Studies The system performance for children and adolescents was evaluated in two separate prospective clinical studies: the Original Pediatric Study (SW10050) and the Software 505 Pediatric Study (SW10505).
subjects’ glucose levels were not intentionally manipulated during this study; in the Software 505 Pediatric Study, subjects ages 13-17 had their glucose levels intentionally manipulated during the clinic session. Readings from the system were reported every 5 minutes and paired with YSI values collected every 15 minutes in order to characterize how well the system readings agreed with laboratory standard BG results.
Table 1-A.
Table 1-B.
Agreement Relative to YSI Agreement between the system and BG values is characterized using paired system and YSI values. The system and YSI results were compared by pairing the YSI BG value to a system glucose reading that occurred immediately after the YSI was collected. The agreement of the system to BG value was assessed by calculating the percentage of system readings that were within 15%, 20%, 30% and greater than 40% of the YSI values.
Table 2-A.
Table 2-B.
mg/dL, the comparisons to the actual BG levels (as determined by the YSI analyzer) when CGM is classified as “LOW” or “HIGH” are included separately in Table 2-A and 2-B. The tables include the numbers and the cumulative percentages when YSI values were less than certain glucose levels (for “LOW”), and when YSI values were greater than certain glucose levels (for “HIGH”).

Accuracy Relative to YSI Accuracy between matched pairs was also estimated by calculating the percent difference between the system reading and the YSI value. For example, if the YSI value is 100 mg/dL and the system reading is 90 mg/dL, a 10% difference between the system and the YSI is reported. The system and YSI values were compared by pairing the system reading that fell immediately after the YSI value was collected.

YSI value was collected. We suggest that you ask your doctor what Alert settings would be best for you. The Low Glucose Alert Estimates of how well the adjustable Low Glucose Alert performs are presented in Table 5-A, 5-B and 5-C. Table 5-A represents the hypoglycemic alert evaluation within 15 minutes of the YSI value in the adult studies.
Hypoglycemia Detection Rate The Detection Rate shows how often the device recognizes and alerts you to an episode of hypoglycemia or how often it misses such an event. The Hypoglycemia Detection Rate is the % of time the BG level was at or below the Alert setting and device alarmed within 15 or 30 minutes before or after the BG was at or below the Alert settings.
Table 6-A.
Table 6-B.
Table 6-C.
The High Glucose Alert Estimates of how well the adjustable High Glucose Alert performs are presented in Table 6-A, 6-B and 6-C. Table 6-A represents the hyperglycemia alert evaluation within 15 minutes of the YSI value in the adult studies. Table 6-B represents the Alert evaluation within 15 minutes of the YSI value for a subset of the pediatric population—subjects age 6 to 17 years who had YSI measurements every 15 minutes.
For example, if you set your High Glucose Alert to 200 mg/dL, how often will your Alarm alert you if your BG goes at or above 200 mg/dL? In the Software 505 Adult Study (Table 6-A), when your blood sugar goes above 200 mg/dL, you can expect your Alarm to sound 98% of the time and not to sound approximately 2% of time within the 15 minute period before or after your blood sugar goes above 200 mg/dL.

Calibration Stability The system must be calibrated every 12 hours. To demonstrate performance of the system over a 12-hour calibration period, systems were evaluated to verify that performance remains consistent over the 12-hour calibration period. Systems were evaluated in 2-hour increments after calibration.
