Pulse pressure: what is it
What is pulse pressure
Pulse pressure is the difference between the systolic and diastolic blood pressure. Normally, it is 40-60 millimeters of mercury. st. By systolic pressure is meant the maximum pressure exerted on the walls of blood vessels, and under diastolic pressure, the pressure on the walls of blood vessels at the end of diastole. The first indicator varies from 100 to 140, the second - from 60 to 90.
Features of pulse pressure measurement
In practice, most doctors focus on the magnitude of random pressure, in other words, on the pulse pressure, which is fixed at the patient at any time during the day. Measurement is carried out using a special medical device - a tonometer. It consists of a sphygmomanometer, which provides compression of the brachial artery and the subsequent registration of the necessary indicators, and a phonendoscope, necessary for listening to the pulsation tones. To get the most accurate view,pulse pressure should be measured in the morning and always on an empty stomach or every three hours for a full day. In people with good health, the daily fluctuations of the systolic index do not exceed, as a rule, 30-35, and diastolic - 10-15.
High pulse pressure
One of the main causes of increased pulse pressure is the high degree of rigidity of the aorta, the largest artery of the human body. This may be due to atherosclerosis - the occurrence of fatty deposits on the vessel walls, or hypertension. The higher the pulse pressure, the harder the aorta will become over time. As a result, the risk of developing various complications will increase. Hyperthyroidism, the presence of defects in the work of the heart valves and iron deficiency anemia can also cause a diagnosis, such as high pulse pressure. Especially often it is observed in the elderly, suffering from coronary heart disease and after myocardial infarction. Early treatment, as a rule, helps to reduce the rate of increased pulse pressure in a short time.The most important thing in this case is not to delay the march to the doctor.
Low pulse pressure
Hypotension or low pulse pressure, that is, a pressure of less than 40 millimeters of mercury, just like high pressure, is not a good indicator and in most cases indicates a lack of cardiac function. Subsequently, it can cause the onset of atrophic changes in the brain, visual impairment and respiratory paralysis. At the very least, low blood pressure can trigger atrophic cardiac arrest. The development of hypotension is especially dangerous in that in most cases it becomes unmanageable, the patient's body stops responding to the introduction of cardiovascular drugs. This condition, as well as high blood pressure, requires a mandatory examination by a specialist and the appointment of appropriate treatment.
