Diabetes Program Blood Glucose Meters Meter measures your
Diabetes Program
Blood Glucose Meters Meter measures your glucose level at that exact time. To see a pattern clearly, you would need to check: before every meal and snack, two hours after every meal and snack, at bedtime, a few times overnight, before and after exercise, whenever feeling high or low. 12 -30 times every day!
What is Continuous Glucose Monitoring (CGM)? CGM is a small, wearable device that tracks glucose levels about every 5 minutes, day and night. Over 250 readings/day Can notify you about highs and lows. Tiny wire sensor is inserted under the skin and measures glucose levels in the subcutaneous fluid Connected to a transmitter that sends the data to a monitoring and display device
CGM vs Blood Glucose Meters CGM gives you a fuller picture Gives you a CGM reading every few minutes, 24 hours a day. Plots data on a trend graph so you can see where glucose levels have been and where they might be heading. Trend arrows show where your glucose is headed and how fast it is changing. Can set high and low glucose alerts so you know if glucose is headed out of range.

CGM vs Blood Glucose Meter CGM reads glucose levels from the interstitial fluid Blood glucose meters read glucose levels from the blood Therefore, the CGM and meter will report different glucose levels, this is normal Readings can be different but are still considered accurate. Usually within 20% of each other, unless the blood sugar levels are rapidly rising or falling FDA Approved for dosing and treatment decisions

Warm up period 2 hours for Dexcom 2 hours for Guardian 12 hours for Libre (14 days – 1 hour warmup) No data during this period Medtronic requires calibration needed at end of warm up period
Calibration for Guardian Connect and Dexcom G 5 and older A finger stick blood glucose level First calibration after the warm up will require a finger stick value Once calibration is entered, CGM display device will start showing data Single Calibration required at least every 12 hours We recommend 2 -4 times a day Before breakfast Before dinner Before bedtime First day of wear may require more calibrations Wash and dry hands prior to finger stick Sugar on skin may falsely elevate number Enter calibration value within 5 minutes
Calibration Best time to calibrate is when blood sugar values are stable: Before a meal First thing in the morning When there are no up or down rate of change arrows on the receiver.
Calibration Do’s and Don’ts Do Use the same meter Use clean hands Don’t If you take Tylenol If BG <40 or >400 If BG rapidly changing
Alarms for Dexcom and Guardian High alarms Set for 250 (more or less depending on preference) Set snooze time for 120 minutes Can set alarm for upward trend arrows (1 or 2 arrows up-rise rate) Can be shut off completely, if needed Low alarms Set for 80 (BG may be <80 by the time the alarm sounds) Set snooze only for 15 minutes (allows time to treat and recheck BG 15 mins later) Can set alarm for downward trend arrows (1 or 2 arrows fallrate)

Trend Graph Prevention of severe hypoglycemia
Daily Life Look at trends over several days before making adjustments. Avoid “reacting” to the number. See if a pattern develops. Blood sugars will rise after a meal but as long as the value comes back to the target range by the next meal, no intervention is needed. Ketone checks only necessary when blood sugar >300 for more than 2 -3 hours on the trend graph. Call the CGM company for technical concerns and if sensors are not lasting the entire 7 -10 day cycle.
