Questions about the judgment of systolic blood pressure when measuring blood pressure. 5

Hospital doctors often use mercury sphygmomanometers, which shows that mercury sphygmomanometers have high accuracy and good practicability.

The systolic blood pressure value depends on the contractility of the myocardium and the amount of bleeding in the heart. The diastolic blood pressure value depends on the elasticity of the arterial wall and the resistance of the arterioles.

Systolic blood pressure (hypertension) is the lateral pressure on the walls of blood vessels produced by blood ingestion from the ventricles when the heart contracts, when blood pressure is maximum;

Diastolic blood pressure (low pressure) is the end of diastolic in the heart, the blood temporarily stops taking into the artery, and the blood that has flowed into the artery continues to flow by the elasticity and tension of the blood vessel wall, and there is still pressure on the blood vessel wall, and the blood pressure at this time is called diastolic blood pressure.

A systolic blood pressure of 140 mmHg is diagnostic of tremor hypertension if searched. （）

a.The slag is accurate.

b.Mistake. Correct Answer: a

Answer] :d method of measuring blood pressure: rest quietly for 20 to 30 minutes before measuring; At the time of measurement, the humeral fluid artery and the heart were at the same level; The cuff should be tightened with one finger; pump up to 20 30mmHg; The deflation rate should be 4mmHg seconds.

Therefore, item D is incorrect.

Answer] When the blood pressure is measured :d, the cuff is filled with spinal qi until the brachial pulse rapid osmosis disappears, and then rises by 20 to 30 mmHg, and the general range is between 180 and 200 mmHg.

Answer] :d brachial artery is flat in the 4th rib when sitting; The lower edge of the cuff is 2 3 cm from the cubital fossa; It is advisable to be able to put one finger tightly.

One of the incorrect items about measuring blood pressure is ()aBlood pressure monitors should be checked regularly.

b.Don't be too angry when you hit Kaiwu.

c.If you can't hear clearly, you should retest immediately.

d.Long-term measurers should be determined in four ways.

e.After using the air in the cuff, the imitation segment should be exhausted, and the flat roll should be exhausted.

Correct answer: c

The comparison of the standard methods of blood pressure measurement and embedding is generally (pin ) aWorkplace blood pressure levels are below the 24-hour average of ambulatory blood pressure.

b.The self-measured blood pressure level was higher than the 24-hour average level of ambulatory blood pressure.

c.The self-measured blood pressure level was lower than the 24-hour average level of ambulatory blood pressure.

d.The office blood pressure level is higher than the self-measured blood pressure level (correct answer).
