Answer

Blood glucose level - 176-200 mg/dL

  • If higher than the last blood glucose level by more than 50 mg/dL, increase rate by 2 U/h.

  • If higher than the last blood glucose level by 20-50 mg/dL, increase rate by 1 U/h.

  • If higher than the last blood glucose level by 0-20 mg/dL, increase rate by 0.5 U/h.

  • If lower than the last blood glucose level by 1-20 mg/dL, remain at the same rate.

  • If lower than the last blood glucose level by 21-40 mg/dL, decrease rate by 1 U/h.

  • If lower than the last blood glucose level by 41-60 mg/dL, decrease rate by half and recheck in 30 minutes

  • If lower than the last blood glucose level by more than 60 mg/dL, stop drip and recheck blood glucose in 30 minutes. If the infusion is turned off, recheck the blood glucose in 30 min. When the blood glucose is more than 175 mg/dL, restart at 50% of previous rate.
