一位顱內壓（ICP）升高的病人，下列哪些是庫欣氏三徵象（Cushing's triad）？（選所有適合的）
Which of the following are classic signs of Cushing's triad in a patient with increasing ICP? (Select all that apply.)
- AIrregular respirations✓ 正解呼吸不規則
- BBradycardia✓ 正解心動過緩
- CWidening pulse pressure✓ 正解脈壓差變寬
- DTachypnea呼吸過速
- EHypotension低血壓
庫欣氏三徵象（Cushing's triad）是顱內壓（ICP）升高導致腦幹受壓的晚期臨床表徵。包括三個核心要素：1.收縮壓升高導致脈壓差（pulse pressure）擴大；2.心跳過慢（bradycardia）；3.呼吸型態不規則（irregular respirations）。這是生命危急徵兆，代表腦疝（herniation）風險極高，必須立即通知醫師並採取降低顱內壓的醫療處置。
Cushing's triad is a late clinical manifestation of brainstem compression caused by elevated intracranial pressure (ICP). It comprises three core elements: 1) rising systolic blood pressure producing widening pulse pressure; 2) bradycardia; 3) irregular respirations. This represents a critical life-threatening sign indicating extremely high risk of brain herniation, requiring immediate notification of the provider and interventions to reduce ICP.
