One value is called " systolic" pressure.

一个值称为“收压”。

In fact, systolic blood pressure goes down.

事实上，收压会下降。

This is your systolic blood pressure.

这就是你的收压。

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

侧心力衰竭是因为收期（或泵送）功能障碍。

Why systolic blood pressure? Why am I mentioning that?

为什么是收压？我为什么要提这个？

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

血压的测量需要用到两个数值。一个是“收压”。

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

只要你的收压在 180 以下，舒张压在 100 以下，你就可以捐献。

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

这被称为单纯收期高压或者单纯舒张期高压。

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压和舒张压，以及如何测量它们。

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

高压（收压）是指心脏将血液泵入血管的力量。

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，收压会因为预期的表现而升高。

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

一般来说，收压和舒张压是同时上升或者下降的，但也并不总是这样。

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

收期血压升高应该在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值范围。

Systolic pressure 90. Get me a Swan.

收压90 给我漂浮导管。

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

收压降至六十 脉细速。

Her systolic blood pressure would rise.

她的收压会上升。

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

她心动过速 收压九十。

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，导致收性心衰。

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，特指收压高于180或舒张压高于110。
