Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Current glucose | 200 |
|---|---|
| Unit | mg/dL |
| Population | Most critically ill patients (target 140–180) |
→Glucose200 mg/dL
- Glucose：200 mg/dL (11.1 mmol/L)
- Target range：Standard 140–180 mg/dL (7.8–10.0 mmol/L)
- Status / management：Above target — ≥ 180 mg/dL (10 mmol/L): start/intensify IV insulin infusion, target 140–180 mg/dL
| Current glucose | 200 |
|---|---|
| Unit | mmol/L |
| Population | Selected populations — postop/cardiac/neuro (may be 110–140) |
→Glucose3600 mg/dL
- Glucose：3600 mg/dL (200 mmol/L)
- Target range：Tighter 110–140 mg/dL (6.1–7.8 mmol/L)
- Status / management：Marked hyperglycemia — Control with IV insulin infusion; investigate DKA/HHS, infection, steroids/parenteral nutrition and other triggers
Common questions
What is Glucose Control in Critically Ill Patients?
Glycemic targets and insulin-management direction for critically ill patients, avoiding both hyperglycemia and hypoglycemia.
How is Glucose Control in Critically Ill Patients calculated? What is the core formula?
Target generally 140–180 mg/dL (7.8–10.0 mmol/L) for most critically ill; start IV insulin infusion when glucose is persistently > 180 mg/dL; avoid tight control (80–110) due to hypoglycemia harm; monitor frequently.
When is Glucose Control in Critically Ill Patients used?
Use in the ICU to select a blood-glucose target band and decide when to start IV insulin infusion, with attention to avoiding hypoglycemia.
What are the key clinical points for Glucose Control in Critically Ill Patients?
A moderate target (140–180 mg/dL) balances the harms of hyperglycemia against the hypoglycemia risk of tight control (original synthesis · not guideline verbatim). Tight glucose control (NICE-SUGAR) increased severe hypoglycemia and mortality, so it is no longer recommended. Frequent point-of-care monitoring and a validated infusion protocol reduce both hyper- and hypoglycemic excursions.
What are the limits and cautions when using Glucose Control in Critically Ill Patients?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
