systolic blood pressure

Systolic blood pressure is an auxiliary test method for checking whether blood pressure is normal. When the heart contracts, the blood taken from the ventricle exerts side pressure on the blood vessel wall, at which time the blood pressure is maximum; at this time, the pressure of the inner wall is called systolic blood pressure, also called high pressure. Systolic blood pressure is clinically significant. There is a type of hypertension called systolic hypertension. It means normal diastolic blood pressure and increased systolic blood pressure. Among various types of hypertension, systolic blood pressure is the most common and more difficult to control. . Through this examination, the lesion and the corresponding symptoms can be judged. Basic Information Specialist classification: cardiovascular examination classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Systolic blood pressure ≤ 120 mmHg is called ideal blood pressure, and systolic blood pressure ≤ 130 mmHg is called normal blood pressure. Normal value: Adult systolic blood pressure: 90-120mmHgmmHg Above normal: Adults with systolic blood pressure ≥ 160mmHg (21.3kPa) can be diagnosed as high blood pressure. negative: Positive: Tips: Maintain a normal diet and schedule. Normal value Systolic blood pressure ≤ 140 mmHg (18.6 kPa) is called normal blood pressure. Clinical significance Abnormal results Clinical observations show that as the systolic blood pressure increases with age, it is more likely to have acute stroke and coronary events. Adults with systolic blood pressure ≥ 160mmHg (21.3kPa) can be diagnosed as high blood pressure. Systolic blood pressure ≤140mmHg (18.6kPa) is called normal blood pressure, between the two, called critical hypertension; so-called hypotension, refers to arterial blood pressure systolic blood pressure below 12 kPa (90 mm Hg). There are different differences in different age groups and genders. The routine physical examination content of the people in need of examination, abnormal blood vessels. Precautions Forbidden before examination: Maintain a normal diet and schedule. Requirements for inspection: The examinee is forbidden to smoke and drink coffee for half an hour, and rest for 5 to 10 minutes in a quiet environment. The patient actively cooperates with the doctor during the examination, and should not be overly stressed during the examination, so as not to affect the result. Inspection process method: 1. The patient should be kept quiet and rested for more than five minutes before the test. 2. Remove the sleeves of the tested limbs to make the blood circulation smooth (usually the right upper limb). 3. The elbow should be at the same level as the heart. When sitting, it should be about the same height as the fourth costal cartilage. When lying, it should be the same height as the midline of the sacral line and abduct 450C. 4. The sphygmomanometer sleeve has a bandwidth of 12-14cm. When measuring, the lower edge of the cuff should be 2-3cm away from the elbow. The air in the air bag is completely released. The middle part is facing the radial artery and is tied to the upper arm. The stethoscope chest should not be pressed under the cuff, but placed on the radial artery at the lower edge of the cuff. Pumping into the cuff, until the beaten artery or radial artery beats, and then raise the mercury column by 20-30mmHg and slowly release the air from the cuff, so that the mercury column slowly drops (2mm/sec is appropriate) to correctly read the result. The pressure value indicated by the first sound is the systolic blood pressure, and the diastolic blood pressure determines the pressure value when the arterial sound disappears. Not suitable for the crowd Inappropriate people: severe blood vessels and heart failure.
