低血容積休克是身體為了代償組織灌流不足而啟動的反應。心跳加速(Tachycardia)與呼吸過速(Tachypnea)是交感神經啟動的早期指標。末梢血管收縮導致皮膚冰冷潮濕。尿量反而會減少(少尿),血壓會下降而非上升。
Hypovolemic shock triggers compensatory responses to maintain tissue perfusion. Tachycardia and tachypnea are early signs of sympathetic activation. Peripheral vasoconstriction makes the skin cool and clammy. Urine output decreases (oliguria), and blood pressure drops rather than rises.
✦ 台美臨床差異
美國護理師常使用早期警示評分(MEWS)來偵測休克前兆;台灣臨床亦逐漸導入類似系統,但強調醫師即時評估。
