If your body needs more blood, then your heart will increase the cardiac output.

如果身体需要更多的血液，则心脏会增加心输出量。

Therefore, if something increases or decreases the heart rate or stroke volume, it will increase or decrease the cardiac output, respectively.

因此，如果某因素增加或降低了心律或每博输出量，则将分别增加或降低心输出量。

All right, so if we simplify this guy a little bit, then the amount of blood that's pumped out by either of the ventricles over a period of time is called the cardiac output.

我们稍微简化一下：在一段时间内，任一心室泵出的血液量，称为心输出量。

What we have from the example just described is a formula for figuring out the amount of blood pumped per minute by each ventricle, what we call the cardiac output.

从刚刚描述的示例中我们得到的是一个公式，用于计算每个心室每分钟泵出的血液量，我们称之为心输出量。

One major short-term fix to wonky blood pressure comes from your brain, which targets both cardiac output and resistance, by altering the distribution of the blood flow around the body, or by changing the diameter of certain blood vessels.

对不稳定血压的一个主要短期解决方案来自你的大脑，它通过改变身体周围血流的分布或某些血管的直径来控制心输出量和阻力。
