Glycemic targets in critically ill adults: A mini-review

Table 1 Types of glycemic targets in intensive care unit

Glycemic target	Unit	Definition
Glucose	mmol/L	Concentration of glucose in blood or plasma. To convert to mg/dL, multiply by 18, i.e., 1 mmol/L = 18 mg/dL
COV	%	Coefficient of variation, a measure of glucose variability. COV = standard deviation divided by mean glucose × 100%
GG	mmol/L	Glycemic gap. GG = blood glucose - [(1.59 × HbA1c) - 2.59], HbA1c being used to estimate average glucose concentration over the prior 3 mo
Glucose variability	mmol/L	Maximum – minimum glucose in a given time period
SHR	Nil	Stress hyperglycemia ratio. SHR = plasma glucose divided by [(1.59 × HbA1c)–2.59], HbA1c being used to estimate average glucose concentration over the prior 3 mo

HbA1c: Glycosylated hemoglobin.
