平均动脉压（MAP）是一次心跳过程中动脉内的平均压力，比单看收缩压更能反映器官的灌注情况。它的计算方法是舒张压加上脉压（收缩压与舒张压之差）的三分之一。MAP 大约在 70–100 mmHg 时，通常被认为足以灌注重要器官。输入您的收缩压和舒张压数值即可获得 MAP 和脉压——此结果仅供参考，不能替代医疗建议。
仅供参考估算，并非诊断。单次测量值会有波动，血压问题请咨询医生。
常见问题
- 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.
