急性心衰竭併肺水腫是危急情況，病人的首要問題是「氣體交換障礙（Impaired gas exchange）」。肺泡內充滿液體導致氧氣擴散受阻，給予高濃度氧氣（Oxygen therapy）是維持細胞代謝、緩解缺氧的最優先護理行動（ABC 原則：Airway, Breathing, Circulation）。
The priority nursing action for acute heart failure with pulmonary edema is administering oxygen to correct hypoxemia caused by impaired gas exchange. Following ABCs, ensuring adequate oxygenation is critical to support cellular metabolism and alleviate respiratory distress.
