The "top" and "bottom" pressure - can explain what is it such or leave the link on this subject?

Arterial pressure is measured in millimeters of a mercurial column that was led from the middle of the last century or blepharon when known French physicist Jean L. M. Puazejl, having pierced heart of an animal the thick needle connected with hollow glass graduated U-by a figurative tube, filled Hydrargyrum, has decided to define or determine delivery force of a cardiac musle. The blood, having rushed in a tube, has displaced (has raised) a serious mercurial column on the certain quantity or amount of degrees. That is experience has gone right, but understand, it is impossible to consider or count comprehensible such bloody way. Search of new methods also has begun. The basic marks on this way were the offer of Italian pediatrist S.Riva-Rochchi (1896) to impose on a brachium the elastic cuff connected to a rubber pear and a glass column with Hydrargyrum, and idea of the Russian surgeon of imperial army N. S.Korotkov (1905) after inflating this cuff to listen to pulse a stethoscope.
The "top" digit corresponds or meets to that force from which the blood presses on vessels during intimate or cardiac reduction, and is called as systolic pressure (in people it or him know as intimate or cardiac) that is not deprived sense: this size reflects a degree of a strain of a myocardium, that power which develops not knowing ustali an organ during this moment. The smaller digit reflects the same force, but in conditions of heart having a rest between two systoles, being designated as diastolic pressure (-obyvatelski "vascular"). And, really, when heart is weakened (in a science such status is called as a diastole), all job on maintenance of a BP is incured with vessels which as you remember, always are in some tonus.
The resume the following: high systolic pressure (160 230 mm hg) - an attribute of a high load on heart (that is bad, but not so is terrible because heart to loads to not get used); high diastolic pressure (90 130 mm hg) reflects narrowing, a vasospasm in all body (that is much more dangerous as conducts to depression of a delivery in the vital organs).
What pressure should be in norm or rate? And what in norm or rate should be color of eyes, force of a brush and tolchkovaja a leg or foot? The answer is clear: at everyone - to a miscellaneous. The norm or rate of a BP too is individual enough. Certain the gold standard of norm or rate , statistically established or installed for young healthy people, - of 120/70 mm hg thus speak a level of pressure: "pioneer" or as at the cosmonaut . But, believe, absolutely quite often it is necessary to accept patients, for which these digits already high because they are adapted for lower sizes (100/65 mm hg, for example). Or, on the contrary: the doctor tries to lower young to the man pressure of 140/80 mm hg to "norm or rate" that leads to development of a giddiness, delicacy, feeling of a nausea for the named level for the person is natural as doctors speak, to "workers".
Therefore rigid norms or rates are not present, pressure will depend on conditions of your job, age, even a floor. The only thing that it is possible to specify absolutely definitely so it is "ceiling" above which takes off AG. At it is triple the fixed or recorded level of a BP of 140/90 mm hg or above it is necessary to address to the doctor. The earlier the debut of a hypertonia will be revealed and there is begun treatment, the it is more than chances to make illness or disease operated or controlled.
