Pulmonary edema is a medical condition characterized by excess fluid accumulation in the lungs. This fluid buildup can interfere with normal breathing and gas exchange, leading to symptoms such as shortness of breath, coughing, and a feeling of suffocation. It often occurs due to heart problems, such as congestive heart failure, but can also result from other factors like pneumonia or exposure to high altitudes. Treatment for pulmonary edema typically focuses on addressing the underlying cause and may include medications like diuretics to reduce fluid overload. In severe cases, oxygen therapy or mechanical ventilation may be necessary to help the patient breathe more easily. Early diagnosis and intervention are crucial for improving outcomes.
