平均動脈壓（MAP）是一次心跳過程中動脈內的平均壓力，比僅看收縮壓更能反映器官的灌流情況。其計算方式為舒張壓加上脈壓（收縮壓與舒張壓之差）的三分之一。MAP 大約在 70–100 mmHg 時，通常被認為足以灌流重要器官。輸入您的收縮壓與舒張壓數值即可取得 MAP 與脈壓——此結果僅供參考，不能取代醫療建議。
僅供參考估算，並非診斷。單次測量值會有波動，血壓問題請諮詢醫師。
常見問題
- What is mean arterial pressure (MAP)?
- Mean arterial pressure is the average pressure in your arteries during one cardiac cycle, and it reflects how well blood perfuses your organs. It is estimated as diastolic pressure plus one-third of the pulse pressure (systolic minus diastolic).
- How do I calculate MAP from my blood pressure?
- Enter your systolic and diastolic readings, and the calculator applies MAP = diastolic + (systolic − diastolic) / 3. It also reports your pulse pressure, the gap between the two numbers, with a simple interpretation.
- What is a normal mean arterial pressure?
- A normal MAP is generally between 70 and 100 mmHg, which is considered adequate to perfuse vital organs. Values below about 60 mmHg may indicate insufficient blood flow, so a persistently low or high MAP warrants medical attention.
