A person s blood pressure is divided into compression and diastolic commonly known as high pressur

Conversion method: 1 mmHg (millimeters of mercury) 0 133 kPa (kiloPascal) standard atmospheric pressure = 760 mm Hg = 76 cm Hg = Pascal = meter water column.

Standard atmospheric pressure values and their variations.

Zhang Jihuai: The regulations on standard atmospheric pressure values have undergone several changes with the development of science and technology. The atmospheric pressure at sea level at a temperature of 0 degrees Celsius, latitude 45° and on a sunny day was originally defined as standard atmospheric pressure, which was equivalent to a height of about 76 cm Hg. Later, it was found that the atmospheric pressure value under this condition is not stable, and it varies according to the influence of wind, temperature, and other conditions.

Therefore, 76 cm Hg height was set as the standard atmospheric pressure value. However, it was later found that the pressure value of 76 cm Hg was also unstable, and the density of mercury changed under the influence of temperature; The g-value also varies with latitude.

In order to ensure that the standard atmospheric pressure is a fixed value, the resolution of the Tenth International Conference on Weights and Measures in 1954 stated that the standard atmospheric pressure value is .

1 standard atmosphere 101325 Newton m2

400 30= The unit is kilopascal.

Multiply by 4 and divide by 30 to get kilopascals.

The unit is kilopascals.

In a patient, the systolic blood pressure is 90 mmHg and the diastolic blood pressure is 60 mmHg, and the average arterial trace pressure is ().

Correct answer to the posture code segment case).

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

a.The slag is accurate.

b.Mistake. Correct Answer: a

Mr. Li Da Zhaoyou, 53 years old, systolic blood pressure 165mmHg and diastolic blood pressure 80mmHg, the following most likely is ().

a.Pericardial effusion.

b.Myocardial infarction.

c.Tachycardia.

d.Arteriosclerosis.

Guess the answer: arteriosclerosis.

Analysis: The normal value of blood pressure is: systolic blood pressure 90 140mmHg diastolic blood pressure 60 90mmHg

The standard large return mu air pressure leakage shield forest is 760mmHg

So systolic blood pressure is 1/8 of the standard atmospheric pressure --- 1/5

Diastolic blood pressure is 1/12 to 1/8 of the standard atmospheric pressure

The systolic blood pressure depends on the contractility of the myocardium and the amount of blood in the heartThe 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 the 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.

Mean arterial pressure = (systolic blood pressure + 2 diastolic blood pressure) 3. It can also be expressed as: mean arterial pressure = diastolic blood pressure + 1 3 pulse pressure difference. Mean arterial pressure = 70 + (100-70) 3 = 80 mmHg

The systolic blood pressure is 100 mmHg and the diastolic blood pressure is 70 mmHg

Friend: This blood pressure seems to be a little low.

I don't know how to calculate this average arterial pressure.

The high and low diastolic blood pressure depends on ().

a.Stroke volume.

b.Peripheral resistance.

c.The elasticity of the aortic starvation slag.

d.Circulating blood volume.

Correct answer: B
