In managing Pulmonary edema/CHF, what type of therapy should be considered?

• A. Low-flow oxygen only
• B. NIPPV/CPAP/BiPAP
• C. High-dose diuretics
• D. Intravenous vasopressor support

Answer: (B)

Noninvasive positive pressure ventilation (NIPPV) such as CPAP or BiPAP is the preferred initial therapy for acute pulmonary edema/CHF because it quickly improves oxygenation and reduces the work of breathing. The mask-delivered pressure helps recruit collapsed alveoli, increasing oxygen exchange, while the positive pressure also lowers venous return and the left heart’s workload, which helps reduce pulmonary edema. This approach can often prevent the need for endotracheal intubation and is especially useful when the patient is cooperative and there are no contraindications. Low-flow oxygen alone may not be enough in significant edema, and while diuretics are important, they act more slowly and aren’t an immediate fix for acute decompensation. Vasopressors are for shock with hypotension and can worsen edema or cause other problems if used inappropriately.
