Hypertensive Emergency Management — free guideline decision tool
This tool separates hypertensive emergency from urgency; for acute ischemic stroke it shows the pre-thrombolysis BP limit < 185/110. Other BP targets and drugs [Pending update].
Open guideline tool →Guideline-based
Implements the decision logic from published clinical guidelines.

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.
| Acute target-organ damage | Present (emergency) |
|---|---|
| Involved target organ (when emergency) | Acute ischemic stroke |
→ClassificationHypertensive emergency (acute target-organ damage)
- BP goal/rate：Acute ischemic stroke: before thrombolysis < 185/110 (Class 1, B-NR; 2026 AHA/ASA §4.3 recommendation 5), per the stroke thrombolysis tool. BP thresholds without thrombolysis [Pending update]
- Preferred drug：Preferred drug [Pending update]
- General rule：Controlled, smooth BP reduction, avoid organ hypoperfusion; IV agents with close monitoring; actively seek the cause and precipitants
| Acute target-organ damage | Absent (urgency) |
|---|---|
| Involved target organ (when emergency) | Eclampsia / severe pre-eclampsia |
→ClassificationHypertensive urgency
- Principle：Markedly elevated BP without acute target-organ damage: gradual oral lowering (time course [Pending update]), no IV or rapid reduction needed
- Disposition：Oral agent choice [Pending update]; find and remove precipitants, arrange follow-up; avoid sublingual short-acting nifedipine causing precipitous drops
- Basis：Chinese Standard for the Diagnosis and Treatment of Hypertensive Emergencies 2020 / Hypertension Clinical Practice Guideline 2024 [Unverified]; stroke item: 2026 AHA/ASA §4.3 recommendation 5
Common questions
What is Hypertensive Emergency Management?
This tool separates hypertensive emergency from urgency; for acute ischemic stroke it shows the pre-thrombolysis BP limit < 185/110. Other BP targets and drugs [Pending update].
How is Hypertensive Emergency Management calculated? What is the core formula?
No acute organ damage → urgency, oral, gradual lowering. Emergency → IV, controlled lowering. Acute ischemic stroke: before thrombolysis < 185/110 (Class 1, B-NR; 2026 AHA/ASA §4.3 recommendation 5), per the stroke thrombolysis tool. Other target-organ BP targets and preferred drugs [Pending update].
When is Hypertensive Emergency Management used?
Use to triage acute target-organ damage to controlled IV therapy, and to manage urgency with gradual oral lowering.
What are the key clinical points for Hypertensive Emergency Management?
Hypertensive urgency is harmed by rapid lowering, so sublingual short-acting nifedipine is avoided and oral agents are used over hours. (original synthesis · not guideline verbatim) Aortic dissection and eclampsia BP targets: [Pending update]. Nitroprusside is contraindicated in eclampsia because of fetal cyanide toxicity.
What are the limits and cautions when using Hypertensive Emergency Management?
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.
Does Hypertensive Emergency Management upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
