Prehospital (EMS) Protocol for Acute Heart Failure \/ Pulmonary Edema During Ambulance Transport<\/div>\n
<\/div>\n
(Adapted from ESC, AHA\/HFSA 2022, NICE 2025, Canada, Australia, Canadian and Australian EMS guidelines)<\/div>\n
<\/div>\n
1. Rapid Recognition (without physician)<\/div>\n
<\/div>\n
Practical EMS Rule for Acute Severe Dyspnea<\/div>\n
1. Any patient presenting with acute severe dyspnea, inspiratory crackles, and low oxygen saturation should be treated as having acute pulmonary edema or acute heart failure until proven otherwise.<\/span><\/div>\n
2. Supporting features include: pink frothy sputum, orthopnea, tachypnea, tripod posture, hypertension, and a history of heart disease or hypertension.<\/span><\/div>\n
3. If the main finding is wheeze without crackles in a patient with asthma or COPD history, consider bronchospasm instead.<\/span><\/div>\n
4. Importantly, EMS is not required to confirm the final etiology; the goal is to ensure safe stabilization and transport.<\/span><\/div>\n
<\/div>\n
How EMS Can Recognize Acute Heart Failure<\/div>\n
1. Primary clues: sudden severe shortness of breath, crackles on chest auscultation, and low oxygen saturation.<\/span><\/div>\n
2. Visual cues: upright sitting posture, agitation, and pink frothy sputum.<\/span><\/div>\n
3. Vital signs: tachypnea, tachycardia, and often elevated blood pressure.<\/span><\/div>\n
4. History clues: known heart failure, coronary artery disease, hypertension, or recent fluid overload.<\/span><\/div>\n
<\/div>\n
If these features are present, EMS should treat and stabilize the patient as acute heart failure \/ pulmonary edema until the diagnosis is confirmed in hospital.<\/div>\n
<\/div>\n
2. Stabilization: Airway, Oxygenation, and BP-Guided Pharmacology<\/div>\n
<\/div>\n
EMS Initial Management of Suspected Acute Heart Failure \/ Pulmonary Edema<\/div>\n
1. Primary Actions<\/span><\/div>\n
<\/div>\n
\u2022 Ensure airway, breathing, and circulation (ABC).<\/span><\/div>\n
\u2022 Position the patient upright.<\/span><\/div>\n
\u2022 Apply monitoring: SpO\u2082, ECG leads, blood pressure, respiratory rate.<\/span><\/div>\n
\u2022 Obtain a brief history (CHF, medications, comorbidities).<\/span><\/div>\n
\u2022 Establish IV access.<\/span><\/div>\n
<\/div>\n
2. Oxygenation and Ventilation<\/span><\/div>\n
<\/div>\n
\u2022 First-line: CPAP\/BiPAP if available and not contraindicated.<\/span><\/div>\n
\u2022 If NIV not available: use high-flow O\u2082, targeting SpO\u2082 92\u201396% (88\u201392% if COPD).<\/span><\/div>\n
\u2022 Prepare for advanced airway only if hypoxemia is refractory or collapse is imminent.<\/span><\/div>\n
<\/div>\n
3. Blood Pressure\u2013Guided Pharmacology<\/span><\/div>\n
<\/div>\n
\u2022 Hypertensive (SBP \u2265110\u2013120 mmHg):<\/span><\/div>\n
* Give sublingual nitroglycerin (0.3\u20130.6 mg) every 5 minutes, up to 3 doses.<\/div>\n
* Check BP before each dose.<\/div>\n
* Contraindications: SBP <100, RV infarct, severe aortic stenosis, recent PDE-5 inhibitor use.<\/div>\n
* IV nitroglycerin is hospital-based, not practical for EMS.<\/div>\n
\u2022 Normotensive (SBP 100\u2013110 mmHg):<\/span><\/div>\n
* Prioritize CPAP and rapid transport.<\/div>\n
* Consider SL nitroglycerin only if SBP is stable and congestion is severe.<\/div>\n
* Loop diuretics may be considered in known CHF with fluid overload.<\/div>\n
\u2022 Hypotensive (SBP <100 mmHg):<\/span><\/div>\n
* Avoid nitroglycerin and diuretics.<\/div>\n
* Give cautious fluids only if hypovolemic.<\/div>\n
* Prepare for vasopressors\/inotropes under physician direction.<\/div>\n
<\/div>\n
5. Role of Loop Diuretics<\/div>\n
\u2022 Not routine in EMS practice (per ESC, AHA, NICE, Canada, Australia).<\/span><\/div>\n
\u2022 May be considered only if: patient has known CHF, already on loop diuretics, shows clear volume overload, and SBP \u2265100 mmHg.<\/span><\/div>\n
\u2022 If administered: IV furosemide 40\u201380 mg, or 1\u20132\u00d7 the patient\u2019s usual home dose.<\/span><\/div>\n
<\/div>\n
6. Non-Cardiogenic Pulmonary Edema (NCPE)<\/div>\n
\u2022 Causes: sepsis, ARDS, neurogenic injury, toxins, TRALI, high-altitude exposure.<\/span><\/div>\n
\u2022 In EMS: differentiation from cardiogenic pulmonary edema is often unreliable.<\/span><\/div>\n
\u2022 Management: oxygen \u00b1 CPAP, supportive care, and rapid transfer to hospital.<\/span><\/div>\n
\u2022 Avoid nitrates and diuretics if NCPE is strongly suspected.<\/span><\/div>\n
<\/div>\n
7. Special Populations<\/div>\n
\u2022 Pregnancy: avoid supine position, use left lateral tilt; provide O\u2082 \u00b1 CPAP; give GTN only with caution if SBP \u2265110; transfer to a cardiac\u2013obstetric facility.<\/span><\/div>\n
\u2022 Elderly: higher risk of hypotension \u2192 always check BP before each SL GTN dose; avoid routine morphine.<\/span><\/div>\n
\u2022 Obesity: use ramped position; ensure CPAP mask seal; higher pressures may be required.<\/span><\/div>\n
\u2022 COPD\/Asthma: aim for SpO\u2082 88\u201392%; try to distinguish wheeze (bronchospasm) from crackles (pulmonary edema).<\/span><\/div>\n
<\/div>\n
8. Contraindications to Nitroglycerin<\/div>\n
\u2022 SBP <100 mmHg.<\/span><\/div>\n
\u2022 Recent use of PDE-5 inhibitors (sildenafil, tadalafil).<\/span><\/div>\n
\u2022 Severe aortic stenosis.<\/span><\/div>\n
\u2022 Suspected right ventricular infarction.<\/span><\/div>\n
<\/div>\n
9. Documentation & Handover<\/div>\n
\u2022 Record vital signs, SpO\u2082, ECG, NIV settings, and SL GTN doses.<\/span><\/div>\n
\u2022 Note the patient\u2019s response to interventions.<\/span><\/div>\n
\u2022 Provide a structured handover to the ED team for continuity of care.<\/span><\/div>\n
<\/div>\n
Key Takeaways for Jordan EMS<\/div>\n
1. Rapid recognition: severe dyspnea with crackles should be managed as acute heart failure\/pulmonary edema until proven otherwise.<\/span><\/div>\n
2. Early CPAP: initiate promptly if available and not contraindicated.<\/span><\/div>\n
3. Sublingual GTN: 0.3\u20130.6 mg every 5 minutes, up to 3 doses, only if SBP \u2265110 mmHg.<\/span><\/div>\n
4. Avoid IV nitrates in the prehospital setting.<\/span><\/div>\n
5. Loop diuretics are not routine; consider only in patients with known CHF, clear fluid overload, and SBP \u2265100 mmHg.<\/span><\/div>\n
6. NCPE (non-cardiogenic pulmonary edema): provide oxygen and supportive measures only.<\/span><\/div>\n
7. Special populations: adjust approach in pregnancy (left lateral tilt), elderly (caution with BP), obesity (ramped position\/CPAP seal), and COPD\/asthma (O\u2082 88\u201392%).<\/span><\/div>\n
8. Hospital pre-alert: notify receiving ED early for rapid transition to advanced management.<\/span><\/div>\n
