What do the two numbers in blood pressure mean??
Answers:
A pretty good range for blood pressure readings is around the 100-120/60-80, this doesn't apply to everyone, because as they say, we are all individuals.
Simply the two numbers represent the pressure within your arteries at two different points in time. The higher (first) number indicates the pressure (measured in milimeters of mercury) that is created when the heart is in maximal contraction. The lower (second) number indicates how low the pressure in the arteries drops before there is another contraction of the heart, which gives you another higher number.
The reason that this is really important information is that your blood vessel system is a closed system, and when the pressure in it gets "too high" it is likely to spring a leak at some weak point in the system. Typically this is in the brain, which is one of the major causes of a Stroke.
The reason that the lower (second) number is important is simply because if the pressure in the arteries doesn't have time to drop prior to the next heart contraction, then the blood does not circulate very efficiently. There are conditions where the first and second numbers get too close together that the blood does not circulate at all.
You want your first number, the high number, to be high enough so that when you suddenly stand-up, you don't faint. So, basically, the lower your first number, the better. As long as there is enough pressure to perfuse the tissues with oxygen, and you don't faint or get dizzy when standing up, you are good to go.
it is the rate your blood is pumping in(top) and out(bottom) of your heart. it should be 130/80 on average
top number is high, bottom number is low.
has to do with the pressure in the walls of the blood vessels at the high and low end.
Anything over 140 is high, anything over 80 for the low number is high.
The systolic pressure is defined as the peak pressure in the arteries, which occurs near the beginning of the cardiac cycle; the diastolic pressure is the lowest pressure (at the resting phase of the cardiac cycle). The average pressure throughout the cardiac cycle is reported as mean arterial pressure; the pulse pressure reflects the difference between the maximum and minimum pressures measured.
Typical values for a resting, healthy adult human are approximately 120 mmHg systolic and 80 mmHg diastolic (written as 120/80 mmHg, and spoken as "one twenty over eighty"), with large individual variations. These measures of blood pressure are not static, but undergo natural variations from one heartbeat to another and throughout the day (in a circadian rhythm); they also change in response to stress, nutritional factors, drugs, or disease. The states in which blood pressure is abnormally high or low are called hypertension and hypotension, respectively.
