blood pressure (BP) is called the power of the blood pressure in the artery wall.It depends on the strength and speed of contraction of the heart, blood properties, the resistance of the vessel walls.
blood pressure is measured in millimeters of mercury, where the first number is the systolic value (or upper) pressure, and the second - diastolic (or lower) blood pressure.
blood pressure norms standards are defined by the World Health Organization classification.
Norma human blood pressure depends on age, lifestyle, work, and the individual characteristics of the organism.
Despite this, there are several categories of blood pressure, which can be guided to make a decision on the treatment for medical or lifestyle changes.
Increasing pressure accompanying physical or psychological fatigue, it may be a sign of an unstable or labile hypertension.
To the doctor should contact, even if in most cases you are not experiencing problems with the pressure.When diastolic pressure greater than 120 mmHgyou need to call an ambulance immediately.
Some diseases can cause norms correction of blood pressure in humans.For example, diabetic patients own blood pressure is defined norm - 130/85 mm Hg, and the pressure is higher than 140/90 mm Hgis a sign of hypertension.
At the same time, the reduced pressure may be normal for athletes experiencing constant heavy loads.
should be noted that the accuracy of blood pressure measurement may be affected by a psychological phenomenon called "white coat syndrome" due to fear and stress in the presence of medical staff and accompanied by an increase in blood pressure of 20-30 mm.Hgto see a doctor or nurse appears.
Norma blood pressure in humans varies with age - the systolic pressure increases throughout life, and diastolic increases of up to 60 years.It should be understood that in the elderly of hypertension risk is great, even though the possible indicators of normal blood pressure.
What is normal blood pressure for different age groups:
In people over 50 years old is especially important to monitor the upper blood pressure - readings above 140 mmHgThey are a cause for immediate treatment to the doctor.
High blood pressure can be a symptom of a heart attack or cerebrovascular accident.Chronic elevated pressure significantly increases the risk of various diseases and complications.
People with high blood pressure the risk of stroke grows by 7 times, 6 times greater chance of developing chronic heart failure, 3-4 times increased risk of peripheral vascular disease and heart attack.
addition, there exists a scheme according to which, starting from the values of 115/75 mmHg, the risk of stroke and heart attack rises with an increase of twice every 20 points of systolic pressure and diastolic 10 points.
If your doctor has recommended to carry out regular measurement of blood pressure at home, it will bring no harm to the clinic and a tonometer with a specialist to determine its possible error.
When motor activity increases blood pressure 20 mm Hg- Is an adequate reaction of the cardiovascular system of the body's needs.Therefore, before the pressure measurement is necessary to come to rest for half an hour to eliminate physical stress and nervous tension, and in 5-10 minutes before the measurement to sit, leaning back in his chair or stool.
also required an hour to refrain from smoking and coffee.In addition, alcohol is contraindicated.Measurement should be carried out on both hands and holds readings with the hand with the highest pressure.It is advisable to measure blood pressure several times at intervals of 5-10 minutes.
Do not forget that constant blood pressure self-help in time to take the necessary measures and to avoid the development of various diseases and expensive treatment.Noticing that some days you have elevated or low blood pressure, rush to apply to the district clinic.Often the early stages of hypertension and hypotension associated with symptoms, taken by mistake for the usual fatigue.
