A 75-year-old female with a known history of chronic obstructive pulmonary disease (COPD) and heart failure is experiencing increased shortness of breath and a productive cough with pink, frothy sputum. She is anxious and sitting upright, leaning forward. Her vital signs are: BP 160/90 mmHg, HR 120 bpm, RR 30 breaths/min, SpO2 85% on room air. Lung sounds reveal diffuse crackles and wheezes. What is the MOST appropriate initial intervention for this patient?
- AAdminister high-flow oxygen via non-rebreather mask and consider CPAP.
- BAdminister aspirin 325 mg orally and prepare for defibrillation.
- CAdminister a bronchodilator via nebulizer and assist ventilations.
- DInitiate immediate IV fluid bolus and place the patient in a supine position.
Show answer & explanationAnswer & explanation
Correct answer: A. Administer high-flow oxygen via non-rebreather mask and consider CPAP.
This patient presents with signs of acute pulmonary edema, likely due to acute decompensated heart failure, exacerbated by her COPD. The severe hypoxia (SpO2 85%) and respiratory distress (pink frothy sputum, crackles, wheezes, tachypnea) indicate a need for aggressive oxygenation. High-flow oxygen via non-rebreather is essential, and CPAP (Continuous Positive Airway Pressure) is highly beneficial in reducing pulmonary edema and improving oxygenation and ventilation by forcing fluid back into the vasculature and stenting open alveoli.
Why the other options are wrong
- B. Aspirin is not indicated for acute heart failure/pulmonary edema. Defibrillation is for pulseless rhythms.
- C. While bronchodilators might help the wheezing component of COPD, the primary issue is pulmonary edema. Assisting ventilations with a BVM may be necessary, but CPAP is often preferred for conscious, spontaneously breathing patients with pulmonary edema.
- D. IV fluid bolus is contraindicated as it would worsen fluid overload. Placing the patient supine would exacerbate shortness of breath and pulmonary congestion.
Acute Pulmonary Edema (CHF) Management
Acute pulmonary edema, often from CHF, requires aggressive oxygenation, positive pressure ventilation (CPAP), and often medications to reduce preload and afterload.
- CPAP improves oxygenation and reduces work of breathing.
- High-flow oxygen is critical for hypoxia.
- Nitroglycerin can help reduce preload and afterload (if BP allows).
