The smaller one. Even small changes of +/- 20 in that are quite harmful
what can cause the top number of blood pressure run up to 159
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.
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 most reputable blood pressure monitors are those made by the USDA, or the United States Data Association who make such devices as blood pressure monitors.
no, it matters with the number not digits
The simple machine of blood pressure is the blood pressure monitor. The monitor is now available at most retail stores for purchase to help individuals keep track of blood pressure at home.
The most important plasma protein for the blood's colloid osmotic pressure is albumin.
The most common low blood pressure symptoms is low sugar levels. Weight loss, headaches, dizziness and there are other symptoms that causes low blood pressure level.
Ventricular contraction. When ventricular pressure exceeds arterial pressure, the ventricles contract and eject blood into the aorta.
Blood is under the most pressure in the aorta- the largest artery in the body originating fro the left ventricle of the heart.
The most you laugh, the more air you take in faster, causing your blood pressure to raise
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.
