Recently often such problem as increase in arterial blood pressure meets at children. And it happens not only to teenagers, but also to children of school and preschool age.
Arterial blood pressure at the child
Modern parents have no sufficient information on the reasons of increase or pressure decline, and sometimes there are even situations, when there is no visible symptoms of these changes happening in the child's organism. To learn to diagnose a problem and to treat the kid, it is necessary to understand causes of this sort of an indisposition in more detail.
Usually children's arterial blood pressure is a little lower, than at adults. This results from the fact that vessels at children are more elastic. It should be noted that pressure of the kid changes in proportion to his age, in other words, the age of the child is less, the value of its arterial blood pressure is lower.
Pressure of the person is designated by figures which have two values. The first speaks about a condition of the top pressure of the person, it is called still systolic which shows result of the maximum pressure rendering a blood stream on walls of vessels. The second value is lower pressure, or diastolic, it shows, on the contrary, the minimum value at the time of relaxation of heart. For measurement of pressure it is accepted to use one of two traditional methods. The first, being the most exact, consists in process of introduction of a needle with the manometer in a vessel. This method received the name invasive. It is rather painful therefore is not suitable for children. The second method means use of the special device of a tonometer and unique method of Korotkov. This option perfectly is suitable for independently measurement of pressure in house conditions, and it does not deliver absolutely any painful and unpleasant feelings.
What values of children's arterial blood pressure
Normal value of arterial blood pressure is 120 on 80. This figure is standard and standard, but the norm can sometimes accept and other values and deviate in various parties. It depends on specific features of an organism of each person and, of course, on age. Children's pressure needs to be calculated, using standard formulas. For example, the value is considered the normal pressure of babies: 76+2kh/46+2kh where "x" is the age which is estimated in months for children to whom year 90+2kh/60+ x, only in this case was already executed "x" will matter, equal to the number of the full years executed to the child. Besides above-mentioned factors, the norm can change depending on growth, build of the child and the structure of a body. Thus, arterial blood pressure of high and full children usually happens above norm, approximately for 10 percent and vice versa.
