Suspend on Low is a feature that is used in conjunction with Continuous Glucose Monitoring (CGM). If the feature is turned on, the pump automatically suspends insulin infusion for up to 2 hours when glucose levels reach a pre-determined threshold. After 2 hours, the pump resumes basal insulin delivery. If blood glucose (BG) is still low 4 hours after resuming basal, insulin delivery re-suspends.
It is important to note that sensor glucose readings are taken from your interstitial fluid (fluid surrounding the cells in your tissue) whereas fingerstick tests are taken directly from your blood. There is a natural lag between glucose levels in the interstitial fluid and glucose levels in the blood. Therefore, it’s normal, and should be expected, for your sensor glucose readings and BG readings to be different but for the most part they should be close.
