But this windless basically tightens this tourniquet to a pressure that is above arterial pressure.

但这个把手可以将这个止血带收紧到高于动脉压的压力。

Mean arterial pressure is defined as the average arterial blood pressure during a single cardiac cycle.

平均动脉压定义为单个心动周期内的平均动脉血压。

Ordinarily, measurements are made of arterial pressure only.

测血压所用的仪器叫血压计。

This is because as arterial pressure increases in the systemic circulation, it gets harder for the left ventricle to pump blood out into that hypertensive systemic circulation.

这是因为随着体循环的动脉压力增加，左心室更难泵血进入高压体循环。

There are three important factors that affect mean arterial pressure: cardiac output, total peripheral resistance, and blood volume.

心输出量，总外周阻力和血容量。

The average arterial blood pressure during a single cardiac cycle is called the mean arterial pressure (MAP).

单个心动周期中的平均动脉血压称为平均动脉压（MAP）。

This arterial pressure that represents the amount of resistance the ventricle has to overcome to eject blood is called the afterload.

心室必须克服以排出血液的阻力的动脉压力称为后负荷。

Mean arterial pressure is influenced by three main factors, including cardiac output, total peripheral resistance, and blood volume.

平均动脉压受三个主要因素影响，包括心输出量，总外周阻力和血容量。

Instead of trying to consider the constant fluctuations of blood pressure, we will look at blood pressure in terms of mean arterial pressure (MAP).

我们将以平均动脉压（MAP）来衡量血压，而不是考虑血压的持续波动。

If not compensated by a decrease in any other variables, we can say that when these three factors increase, so does the mean arterial pressure.

如果没有通过其他任何变量的减少来补偿，我们可以说，当这三个因素增加时，平均动脉压也会增加。

If not compensated by a decrease in other variables, we can say that when these three factors increase, so does the mean arterial pressure.

如果不能通过其他变量的减少来补偿，我们可以说，当这三个因素增加时，平均动脉压也会增加。

The CSF is held under a little bit of pressure, below 200 mm of H2O, which is just under 15 mm of mercury - - which is less than a fifth of the mean arterial pressure.

脑脊液承受一定的压力，在200毫米水柱以下换算成汞柱，只在15毫米汞柱以下——小于五分之一的平均动脉压。

The higher the cardiac output, the higher the mean arterial pressure, because there is more blood being pumped out of the heart and flowing into the arterial system.

心输出量越高，平均动脉压越高，因为有更多的血液从心脏泵出并流入动脉系统。

Now though the optimal post-cardiac arrest blood pressure remains unknown; a mean arterial pressure of 65 mm of Mercury or greater is a reasonable goal per scientific studies and current guidelines.

现在，尽管最佳的心脏骤停后血压仍然未知；根据科学研究和现行指南，平均动脉压为 65 毫米汞柱或更高是一个合理的目标。
