Patient handout

Hypertensive emergency with acute (flash) pulmonary edema

PRODUCTION

1. Your condition

This handout is for hypertensive emergency with acute (flash) pulmonary edema. Your care team identified this based on: sbp >180 + acute respiratory distress + bilateral b-lines / pulmonary edema on cxr (acc/aha 2025; vaughan lancet 2000 pmid 10972386).

Other reasons your team may use this plan: acute dyspnea + orthopnea + pink frothy sputum (classic flash pulm edema); lung us with diffuse b-lines (lr+ 13 per lichtenstein blue protocol pmid 18403664).

2. Your medications

Take these medications exactly as prescribed. Do not stop or change a dose without talking to your provider.

MedicationStarting doseHowWhenWhat it does
nitroglycerin5-10 µg/min IV, titrate by 5 µg/min q5min up to 200 µg/minIVcontinuousACC/AHA 2025 first-line — preload + afterload reduction; rapid onset; PAGE-PE supports early titration (PMID 33872318); AVOID if SBP <90 / RV infarct / PDE5 within 24-48h
furosemide40-80 mg IV bolus (or 1-2× home daily dose if chronic HF) per DOSE PMID 21366472IVq12h or continuous infusion 5-20 mg/hDOSE trial (Felker NEJM 2011 PMID 21366472) — high-dose IV + bolus or continuous; reassess UOP at 2 h; titrate to net negative balance
nicardipine5 mg/h IV titrate by 2.5 mg/h q5-15 minIVcontinuousAdd when NTG alone insufficient or contraindicated; safe with HF (does not worsen LV function)
nitroprusside0.25-10 µg/kg/min IV titrateIVcontinuousRapid afterload reduction; AVOID if eGFR <30 (cyanide) OR coronary ischemia (coronary steal); ACC/AHA 2025 acceptable adjunct
labetalol20 mg IV q10 minIVbolusCautious use — BB in acute decompensated HF can worsen — only if tachycardia + EF preserved + responding to NTG/diuretic
NIPPV (CPAP 8-10 cmH2O or BiPAP 12/5)CPAP 8-10 cmH2O OR BiPAP IPAP 12 / EPAP 5; titrate to SpO2 >92maskcontinuous3CPO trial (Gray NEJM 2008 PMID 18768944) — NIPPV reduces intubation rate vs standard O2 in cardiogenic pulm edema; equivalent CPAP vs BiPAP
AVOID isolated diuretic without vasodilatorAVOIDN/AN/ADiuretic alone without afterload reduction in HTN-driven flash edema is incomplete unloading — preload + afterload reduction with NTG is the FIRST move (ACC/AHA 2025; ESC 2021 HF PMID 34447992)

Plan: Flash pulm edema + HTN — preload + afterload reduction FIRST (IV NTG) + IV loop diuretic + NIPPV; goal SBP ↓ 25% in first hour

3. When to call your provider

Contact your care team if any of the following happen:

  • Weight gain trigger → clinic
  • Symptom recurrence → reassessment

4. When to seek emergency care

Call 911 or go to the nearest emergency room right away if you have:

  • oxygen level (SpO₂) <85 on NIPPV with FiO2 100% OR worsening RR/AMS despite NIPPV — failure of non-invasive support(life-threatening)
  • Positive troponin or dynamic ST changes in flash pulmonary edema — ACS-driven flash edema (often anterior STEMI with acute LV failure)(life-threatening)
  • Flash pulm edema + SBP <90 + lactate ≥2 + organ hypoperfusion — SCAI C+ cardiogenic shock(life-threatening)
  • Rising Cr (>30% from baseline) during diuresis OR persistent edema + AKI — cardiorenal syndrome
  • New severe MR or AR (papillary rupture, endocarditis, dissection-related AI) presenting as flash pulm edema(life-threatening)

5. Follow-up

Transition to oral 4-tier ladder + the four foundational heart-failure medications if HFrEF; secondary cause workup (RAS, OSA, dietary indiscretion, medication non-adherence); 1-week follow-up; cardiac rehab if first HF episode
