One value is called " systolic" pressure.

一个值称为“收缩压”。

In fact, systolic blood pressure goes down.

事实上，收缩压会降。

Why systolic blood pressure? Why am I mentioning that?

为什么是收缩压？我为什么提这个？

Blood pressure is measured using two values. One value is called " systolic" pressure.

血压的测量需用到两个数值。一个是“收缩压”。

This is your systolic blood pressure.

这就是的收缩压。

As long as your blood pressure is below 180 systolic and 100 diastolic, you may donate.

的收缩压在 180 ，舒张压在 100 ，就可捐献。

This is referred to as isolated systolic hypertension or isolated diastolic hypertension.

这被称为单纯收缩期高压或者单纯舒张期高压。

The top number, called systolic, represents the force with which your heart pumps blood into the blood vessels.

高压（收缩压）是指心脏将血液泵入血管的力量。

Typically, both systolic and diastolic pressures tend to climb or fall together, but that's not always the case.

一般来说，收缩压和舒张压是同时上升或者降的，但也并不总是这样。

We also talked about what systolic and diastolic blood pressure are, and how they're measured.

我们还讨论了什么是收缩压和舒张压，及如何测量它们。

When we're gearing up to do something hard, systolic blood pressure goes up in anticipation of the performance.

当我们准备做一些困难的事情时，收缩压会因为预期的表现而升高。

Elevated systolic blood pressure is considered between 120 and 129 mmHg and less than 80 mmHg on the diastolic side.

收缩期血压升高应该在120到129mmHg之间，舒张期血压则是应该在小于80mmHg的区间内。

Sometimes, you can have systolic or diastolic hypertension, when one number is normal and the other is really high.

有时会出现收缩期或者舒张期高血压，即一边的数值很高，但是另一个却处于正常值范围。

More demand and reduced supply means that some of the ventricular muscle starts to have weaker contractions —leading to systolic failure.

需求增大而供血减少，意味着一些心肌开始虚弱地收缩，导致收缩性心衰。

Another cardiogenic cause is severe systemic hypertension - specifically a blood pressure that is greater than 180 systolic or 110 diastolic.

另一个心源性因素是严重的全身性高血压，特指收缩压高于180或舒张压高于110。

Usually left-sided heart failure is caused by systolic (or pumping) dysfunction.

通常左侧心力衰竭是因为收缩期（或泵送）功能障碍。

Systolic's down to 60. Pulse is getting thready.

收缩压降至六十 脉细速。

Systolic pressure 90. Get me a Swan.

收缩压90 给我漂浮导管。

Now, 'normal' systolic blood pressure is defined as less than 120 mmHg, and a normal diastolic pressure is less than 80 mmHg.

现在，正常的收缩期血压被定义在120mmHg，正常的收缩压则是应该小于80mmHg。

She's tachy. B.P. of 90 systolic.

她心动过速 收缩压九十。
