What is the normal pressure?
Blood pressure is the pressure thatblood exerts on the walls of the arteries. This is one of the most important parameters of human health, and therefore it is important to know which indicators are the norm, and which ones are pathologies.
From the work of the cardiovascular system dependsblood supply of all organs and tissues, and hence the state of human health. The function of the pump that pushes the blood is performed by the heart, and the vessels are a kind of "transport routes" through which the blood circulates in the body. During the contraction of the cardiac muscle in the vessels, the maximum blood pressure is created - systolic, during relaxation - minimal, or diastolic. It is these indicators that are needed to evaluate the functioning of the circulatory system. Ideal is the ratio 120/80 mm. gt; st., where the upper digit shows systolic, and the lower one - diastolic pressure. However, slight fluctuations in one direction or the other do not exceed 10 mm. gt; Article, should not cause concern. In addition, not only the absolute value of blood pressure, but also the difference between the upper and lower index is important. Normally, it should not exceed 30-40 mm. gt; see The level of blood pressure depends on many factors: the age of the person, the diameter of the vessels, the intensity of the heart and the volume of circulating blood. In case of large blood loss, for example, the pressure becomes lower, and when the volume of circulating blood increases, for example, if the kidneys are disturbed, the pressure rises. To become higher, it can also for other reasons: during intense physical activity, because of the narrowing of the lumen of the vessels, heart diseases, diabetes mellitus, etc. A decrease in blood pressure is called hypotension, and hypertension is an increase. Significant fluctuations in blood pressure are fraught with not only poor health, but also serious consequences, such as a syncope, a heart attack or a stroke. Symptoms of hypotension are weakness, dizziness, mild nausea, drowsiness. On hypertension can indicate a headache, darkening and pain in the eyes, shortness of breath, rapid heartbeat. However, in some cases, pressure fluctuations are not felt, which is why it is important to monitor the indicators with a tonometer. The risk of cardiovascular disease increases if the pressure stably exceeds the norm. Persons who have blood pressure from 140/10 mm. gt; Art. and above, need not only dynamic observation, but also in the treatment. In the event of hypotension or hypertension, it is important to undergo an examination with a cardiologist or therapist. Most likely, the doctor will prescribe an electrocardiogram, urinalysis, a general and biochemical blood test, a blood test for sugar, an ultrasound of the heart and kidneys.
