About Alarms
“When I checked my blood glucose with my meter, it was high, but I did not
get a HIGH alarm….”
Keep in mind, there may be short-term dierences between your meter BG and the sensor glucose.
This often happens after a meal, when your glucose is rising. Look at the 3-hour trend graph. This will
tell you if your glucose is rising but is not yet at the alarm level you set.
“My HIGH GLUCOSE or LOW GLUCOSE alarm is going o too often or not
often enough….”
Remember that if your alarm settings are not working well for you – you are getting too many alarms
when your glucose levels are not high or low or you are not getting alarms soon enough – you can
check with your healthcare provider for recommendations on adjusting your settings.
“My meter BG was low, but I did not get a LOW alarm….”
Keep in mind, there may be short-term dierences between your meter BG and the sensor glucose.
Look at the 3-hour trend graph. This will tell you if your glucose is dropping but is not yet at the alarm
number you set.
My meter BG is normal, but I got a LOW GLUCOSE alarm….”
Over time, you will learn the best settings for your alarms. Some people do not mind extra alarms if it
helps them spot more lows. Other people do not want the alarms and put their settings at dierent
ranges.
“I got a HIGH GLUCOSE alarm, and it keeps alarming even though I already
treated….”
Insulin takes a while to start working. You can do 2 things to stop the alarm while you wait for your
glucose level to go down. One is raising your HIGH GLUCOSE alarm for a short time. The other is
setting the SNOOZE to check again after a longer period (up to 3 hours).
Icons Denition
Sensor
Icon shows normal signal between glucose sensor and insulin
pump/monitor
Icon shows no signal from glucose sensor
Arrow
One up arrow shows that your SG has been rising at a rate of
1 mmol/L over the previous 20 minutes
One down arrow shows that your SG has been falling at a rate of
1 mmol/L over the previous 20 minutes
Two up arrows shows that your SG has been rising at a rate of
2 mmol/L (or greater) over the previous 20 minutes
Two down arrows shows that your SG has been falling at a rate of
2 mmol/L (or greater) over the previous 20 minutes
You can use the graphs to potentially learn…
• What is my glucose level now?
• Is my glucose going up, going down, or staying about the same?
• Was my Carb Ratio right for that meal?
• Is the timing of my bolus right?
• Was the type of bolus (normal, square, or dual) right?
• What happened in the past few hours to lead me to a low or high?
• How did I respond to exercise?
• How is my glucose control over various periods of time (3, 6, 12 or 24 hours)?
• Check in the morning to see overnight glucose trends
• Check between-meal glucose trends
There are a few conditions which can prevent a continuous sensor glucose
measurement from being taken…
• A Lost Sensor alert
• A Sensor Error alert
• A Change Sensor alert
• A new sensor that you just inserted is being initialised
• A Cal Error alert (calibration Error)
• More than 12 hours have passed since you last calibrated
• Find Lost Sensor (15 minutes)
• Weak signal
• Reconnect old sensor (two hours)
