Final answer:
The initial treatment for acute pulmonary edema usually involves loop diuretics like furosemide to quickly reduce fluid overload in the lungs.
Step-by-step explanation:
The initial treatment for acute pulmonary edema, a medical emergency, typically includes a class of medications known as loop diuretics. The most commonly used loop diuretic is furosemide (Lasix). This medication works to quickly reduce fluid overload by increasing urine production, thereby helping to relieve the pressure and fluid accumulation in the lungs. Additionally, oxygen is administered to help with breathing difficulties, and in some cases, other medications might be given, such as nitrates, which help to dilate blood vessels and reduce the workload on the heart.
