Glucose parameters. The “Lower Grid” parameter selection window demonstrates the various glucose parameters that may be used for blood glucose entry: Gluc (S), serum glucose; Gluc (POC), point of care glucose testing with a bedside glucometer; and Gluc (ILG), ILGem (Instrumentation Laboratory, Bedford, Massachusetts)–measured glucose. Documenting any of these glucose parameters restarts the countdown timer for the next measurement.
