I move my alarm settings several times each day depending on whether I expect a fall or rise. For example after eating I set the high at 140 which is the lowest for high alarm, I wish it could even go lower because with lag time between blood and interstitial readings you can get quit high Bg before the CM gets to 140. Then once I’ve done my correction for high Bg I turn off the high alarm, so I don’t have to listen to it continually going off, then I move the low alarm up say to 120 or 130 so as my Bg falls from my correction I can catch the drop early enough to stop any hypo.
Another thing I do is have different sounds for each. I have the low on “high beep” and high on “vibrate” that way I can tell just from which sound which way I’m going without having to take it out of my belt pouch, just have to push the buttons. (I use a soft pouch). Also I set the system alarms on low beep to differentiate between a low glucose and any of the other types of alarms.
Sometimes the alarms can get annoying, I have been known to yell at the thing “I know quit bothering me!”
