diastolic blood pressure

Diastolic blood pressure is an auxiliary test method for checking whether blood pressure is normal. Diastolic blood pressure is the diastolic pressure, also called low pressure, when the arterial blood vessels are elastically retracted when the heart is dilated. Through this examination, the lesion and the corresponding symptoms can be judged. 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. Basic Information Specialist classification: cardiovascular examination classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain a normal diet and sleep. Normal value The normal diastolic blood pressure of adults is <90 mmHg (12 kPa), the unit of blood pressure is kPa, and 1 kPa = 7.6 mmHg. Clinical significance Abnormal results According to the World Health Organization, when the adult diastolic blood pressure is ≥95mmHg (12.6kPa), it can be diagnosed as hypertension. Somewhere in between, called critical hypertension. Many middle-aged people, due to work stress, less activity; blood pressure systolic pressure is normal, diastolic blood pressure is higher than 90 mm Hg, sometimes pulse pressure difference is very close, such as 130/110 mm Hg, patient subjective feeling Dizziness, chest discomfort. This is due to increased sympathetic activity and increased peripheral vascular resistance. It is an early stage of hypertension. 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.
