Managing Hypertensive Emergencies
Guides urgent blood pressure management with target reduction rates and IV medication protocols.
Why This Skill Exists
Hypertensive emergencies — defined as severely elevated BP (often > 180/120 mmHg) with acute end-organ damage — carry mortality rates of 1–2% per hour if untreated. The distinction between hypertensive emergency (end-organ damage present) and hypertensive urgency (elevated BP without acute damage) is critical, as management strategies differ fundamentally: emergencies require IV therapy with controlled rate of BP reduction, while urgencies can be managed with oral agents.
The 2017 ACC/AHA Hypertension Guideline and critical care consensus documents define target reduction rates specific to each end-organ presentation. Overly rapid BP reduction risks watershed infarction, especially in patients with chronic hypertension whose autoregulatory curve is right-shifted.
