The smaller one. Even small changes of +/- 20 in that are quite harmful

What does the 3 numbers blood pressure reading mean?

A blood pressure reading consists of two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number). The systolic pressure measures the pressure in the arteries when the heart beats, while the diastolic pressure measures the pressure in the arteries when the heart is at rest between beats. The third number, if present, is the pulse pressure, calculated by subtracting the diastolic pressure from the systolic pressure. This number gives an indication of the force the heart generates with each contraction.


How blood pressure is greater than atmospheric pressure?

Blood pressure is the blood flow when the heart is pumping (top number) and when the heart is resting (bottom number). The body is a closed system and requires enough blood pressure to pump the blood throughout the body. A typically healthy blood pressure would be 120mmHg/70mmHg. Atmospheric pressure is the weight of the atmosphere at a specific location and altitude. At sea level, atmospheric pressure is 760mmHg. So actually, atmospheric pressure is much greater than blood pressure. Most people never have to worry about atmospheric pressure affecting blood pressure. However, deep sea divers experience an increase in blood pressure while diving, and astronauts experience a decrease in blood pressure when in space.

The difference between systolic and diastolic pressures?

Systolic BP should always be higher than diastolic BP.The number on the top is the systolic blood pressure and the number on the bottom is the diastolic blood pressure. The systolic BP is the pressure in the arteries right when the blood is pumped out of the heart, therefore the pressure is bigger. The diastolic BP is the pressure in the arteries after the blood has been pumped out and before the next heart contraction. At this moment, the heart is relaxed and the pressure is much lower.
