The doctor or therapist sets a blood pressure cuff on the upper arm and he blows it over the expected blood pressure. Is the pressure is slowly reduced, so a so-called Korotkov noise over the brachial (brachial artery”) or Radialis artery occurs first, which can be heard using a stethoscope. The Korotkov – noise decreases and disappears altogether. The pressure measured at the beginning of the occurrence of the included noise, is the systolic blood pressure value. The lower that diastolic pressure is reached, if the noise is quieter.
During the investigation, the child patient should be relaxed as far as possible. This child, the cuff must be at heart level; that seated child should put his arm on the table. The cuff must consistently include the arm, the width of the cuff should be about half of the size of the arm. In the child patients, different cuff sizes from 2.5 to 12.5 are available. Under no circumstances, cuff width of adult patients are to use. It is important that the doctor and the healer in the child patients provides corresponding cuff sizes. Each child patient, whose blood pressure is several provisions above the 95th percentile, receives a blood pressure measuring device, so that it can control his blood pressure regularly independently.
Parental training is required. The cost normally take the legal health insurance companies in the Federal Republic of Austria and the Federal Republic of Germany with a child patient with diagnosed hypertension. In newborns, infants and young children the blood pressure measurement after Riva-Rocci and Korotkov usually not possible or is inaccessible. It applies to child patients to purchase devices or to hold, which directly register the virtually inaudible in this age Korotkov sounds through the microphone on the lower edge of the cuff, or but record the occurrence of Jolt arterial blood flow below the cuff as a criterion of Systole by means of ultrasound and electronic registration.
