题目：血压和器官灌注

Which patient has a better blood pressure, the patient with a blood pressure of 110/40 or the patient with a blood pressure of 90/60?
哪一个病人的血压好一点，血压110／40或血压90／60？
 
Mean arterial pressure (MAP) is generally considered to be the organ perfusion pressure in an individual. Because MAP requires an inconvenient calculation, we've all been taught...misled perhaps...into focusing on systolic blood pressure (SBP) as a marker of how well-perfused a patient is, and we tend to ignore the diastolic blood pressure (DBP).
对一个个体来说，平均动脉压（MAP）一般被认为是器官灌注压。由于MAP需要计算得出，我们在过去所学到的（也可能是被误导），收缩压（SBP）是评定一个病人灌注好坏的指标。以至我们经常忽视了舒张压（DBP）。
 
It's important to remember, however, that we spend most of our lives in diastole, not systole. As a result, our organs spend more time being perfused during diastole than systole. The MAP takes this into account: MAP = (SBP + DBP + DBP)/3. DBP is more important than SBP!
但是，一定要记住，在我们一生中，花在舒张期的时间最多，并不是在收缩期。 也就是说，我们各个脏器在舒张期得到的灌注要比收缩期多得多。在MAP的计算中对这个问题也有所考虑：MAP＝（SBP＋DBP＋DBP）／3。DBP要比SBP重要！
 
So which patient is perfusing his vital organs better, the one with a BP of 110/40 or the one with a BP of 90/60? Do the MAP calculation...90/60 is better than 110/40!
这样，哪一个病人灌注他的脏器更有效，是血压为110／40的病人，还是血压为90／60的病人？算一下MAP…90／60要好于110／40！
 
Pay more attention to those diastolic BPs!
要多留意舒张压！
