Pulmonary Edema Handwritten Nursing Notes PDF Download | Simple Nursing Notes

Pulmonary edema is the abnormal accumulation of fluid in the alveoli and interstitial spaces of the lungs, which impairs gas exchange and leads to respiratory distress. Prompt recognition and immediate nursing interventions are essential.

Causes (Etiology)

Cardiogenic Causes

• Left ventricular failure
• Acute myocardial infarction (MI)
• Severe hypertension
• Valvular heart diseases (eg. mitral stenosis)

Non-Cardiogenic Causes

• Acute Respiratory Distress Syndrome (ARDS)
• Pneumonia and severe infections (sepsis)
• Renal failure (fluid overload)
• High altitude pulmonary edema
• Drug overdose, inhalation injury, trauma

Pathophysiology (Short Notes)

• Left ventricular dysfunction → ↑ pulmonary capillary pressure.
• Fluid leaks from pulmonary capillaries into interstitium and alveoli.
• Alveolar flooding → impaired oxygenation and CO₂ retention.
• Severe cases show pink, frothy sputum and hypoxia.

Signs & Symptoms

• Acute onset breathlessness (dyspnea)
• Orthopnea and paroxysmal nocturnal dyspnea
• Tachypnea, tachycardia
• Fine crackles (rales) on auscultation
• Pink frothy sputum in severe cases
• Cyanosis, diaphoresis, anxiety, restlessness

Investigation / Diagnosis

• Chest X-ray: bilateral alveolar infiltrates / "butterfly" pattern
• Arterial Blood Gas (ABG): hypoxemia ↓ PaO₂
• ECG and cardiac enzymes (for cardiac causes)
• Echocardiography: left ventricular function
• BNP (Brain natriuretic peptide) elevated in cardiogenic cases

Immediate Management

• Ensure airway patency; high-flow oxygen therapy (mask or NIV as indicated)
• Place patient in upright (Fowler’s) position to reduce venous return
• Establish IV access and monitor vitals continuously
• Prepare for advanced airway management if respiratory failure develops

Medical Treatment

• Diuretics: IV Furosemide — reduces preload and pulmonary congestion
• Vasodilators: Nitroglycerin for cardiogenic pulmonary edema (if not hypotensive)
• Inotropes: Dobutamine if poor cardiac output
• Morphine: (used selectively) to reduce anxiety and venous return
• Treat underlying cause (eg. revascularization for MI, antibiotics for pneumonia)

Nursing Management (Exam-friendly Points)

• Assess airway, breathing and circulation (ABCs) frequently
• Administer oxygen and monitor SpO₂ continuously
• Record strict input & output and daily weights
• Monitor urine output after diuretics
• Observe for chest auscultation changes and sputum character
• Provide emotional support and explain procedures to reduce anxiety
• Position patient upright; encourage slow, deep breathing as tolerated
• Document all interventions, medication times and patient response

Complications

• Respiratory failure requiring mechanical ventilation
• Cardiac arrest
• Hypoxic organ injury

Prevention & Patient Education

• Control hypertension and heart disease; adhere to medications
• Advise salt restriction and fluid management where indicated
• Teach early signs of breathlessness and when to seek care
• Encourage smoking cessation and healthy lifestyle

Quick Revision Points

1. Pulmonary edema = fluid in alveoli → impaired gas exchange.
2. Cardiogenic (LVF) vs non-cardiogenic (ARDS, sepsis).
3. Immediate: oxygen, position upright, IV access.
4. Main drugs: IV furosemide, nitrates, inotropes if needed.
5. Nursing: monitor SpO₂, urine output, I/O, auscultation, documentation.
