Test Cases for Electronic Blood Pressure Monitors? Introduction to electronic sphygmomanometer measu

If you're 20-30 years old, your first high and low blood pressure measurements are normal but your heart rate is too slow.

If you're 30 to 50 years old, your second high and low blood pressure measurements are also within the normal range, which is also a slow heart rate.

Blood pressure monitor knowledge: the measurement results and causes of blood pressure.

1. Causes of increased blood pressure

White coat hypertension (measured in the hospital).

Nervousness, worry, anxiety.

The armband is too loose for bloating.

After coffee, black tea, cigarettes.

After exercise or work.

There was a urge to urinate The room was too cold.

Interrupt taking blood pressure medications.

2. Correct measurement method

In a warm room.

Every day at the same time.

Sit in a chair with your back straight.

Armband fastened The armband is the same height as the heart.

Take a few deep breaths to relax.

3. Causes of low blood pressure

The armband is pleated under the sleeves.

After bathing or drinking.

Several measurements in a row.

The armband is higher than the heart.

4. The reason why the blood pressure value measured each time is differentEvery day is not measured at the same time.

Several measurements in a row.

The posture at the time of measurement is different.

Armband ties are different.

The mental state is not the same.

5. "EE" is displayed, which cannot be measured

The armband is not tied correctly.

The pressurization value is set too low.

6. Display "e", can not measure

Arm movement or speech during compression or measurement.

Rolled up sleeves measure.

The armband is tied too loosely.

The markings on the armband do not properly touch the upper brachial artery.

The pulse is too weak. 7. Repressurize

Insufficient compression: The wrist is moving during compression or measurement.

Measurement is affected by noise and noise.

The armband is tied too loosely.

8. When pressurized, the number stops halfway and no longer risesThe armband is not well connected to the body and leaks.

The armband is broken, and it leaks.

Blood pressure measurement method, electronic blood pressure monitor measurement method.

Electronic sphygmomanometer.

The electronic blood pressure monitor can display blood pressure and pulse accurately and quickly. The digital display blood pressure and pulse meter digitally processes the signal sampled by the transducer to directly display three parameters: systolic blood pressure, diastolic blood pressure and pulse. The instrument adopts an automatic decompression device and does not require a stethoscope.

1. Install the battery (pay attention to the positive and negative polarity), plug in the signal plug and gas plug.

2. The patient should lie on his back or sit so that the microphone is at the same height as the heart, relax the forearm, and bend the arm slightly inward.

3. Place the segment wax mark of the transducer correctly at the brachial artery, and tie the cuff to the upper arm.

4. Estimate the highest blood pressure of the person being measured, put a certain number on the number key, and then quickly pressurize until the instrument makes a beep sound, that is, start the decompression measurement until the end. The instrument displays the systolic blood pressure value and the diastolic code slip pressure value. Press the pul key and the pulse count will be displayed.

When this key is relaxed, the blood pressure value is displayed again.

5. Press the button next to the balloon to release the gas, remove the cuff and record it.

1. Use the machine according to the instrument manual.

2. The patient should be quiet before the measurement, and avoid the vibration of the instrument during the measurement.

3. The position should be correct when measuring blood pressure, and rest for a while when repeating the measurement. The cuff should not be wrapped too tightly, and it is advisable to insert one finger.

4. Pumping should be continuous, in one go, and stop after hearing the "beep" sound.

As you get older, your blood pressure also needs to be monitored regularly, so that you can judge your health according to your blood pressure value. Commonly used blood pressure monitors include electronic blood pressure monitors and mercury blood pressure monitors, which are more accurate than the two, but the operation is a little troublesome. In fact, the numerical monitoring of the electronic blood pressure monitor is also relatively accurate, as long as you ensure that your heart is in a stable state and there is no strenuous activity.

If you don't feel accurate, you can also take two consecutive measurements to take an average. <>

Many people will have an electronic blood pressure monitor at home, this is to monitor the blood pressure of the elderly. The elderly are the most susceptible to hypertensive diseases, and if they are not careful, they are likely to form a hypertensive crisis, and even have serious harm to life. Electronic sphygmomanometers are more commonly used among many sphygmomanometers, and their accuracy is recognized.

It may be that with the high purchase rate of blood pressure monitors, merchants do not pay much attention to the accuracy of blood pressure monitors, so they can go to the hospital to buy them. <>

The measurement value of foreign electronic sphygmomanometer is very accurate, if you have the ability, try to use foreign electronic sphygmomanometer as the mainstay, and electronic sphygmomanometer is divided into closed and wrist type, if you want to measure more accurately, you must choose closed. If you suspect that the blood pressure monitor is not accurate, you can also take your own blood pressure monitor to the hospital and ask a medical professional to help you calibrate it. You can also compare the values measured by your own blood pressure monitor with the blood pressure monitor in the hospital, and you can know the difference between the two.

Therefore, when you measure again in the future, you can also subtract the difference to get a correct blood pressure value. <>

Although the mercury sphygmomanometer is more accurate, it is more difficult to operate, and it is not suitable for one person to use alone, so in addition to measuring the electronic blood pressure value every time, you can also regularly go to the pharmacy or clinic next to your home to use the mercury sphygmomanometer to measure again, so that you can see the changes in your blood pressure value very well. Moreover, the use of mercury sphygmomanometer requires professional operation, so if a layman operates it, there may be mistakes.

It must be very accurate, this electronic instrument can accurately measure blood pressure, will reduce external interference, and the value will be more accurate.

I think it is more accurate, based on the fact that the electronic sphygmomanometer detects your blood pressure through a certain electronic device principle, and the blood pressure value presented by the information fed back by your body.

The measurement of electronic sphygmomanometer is not particularly accurate, because the electronic sphygmomanometer will be affected by some external influences when measuring, and if the arm is uneven, the blood pressure will also increase or decrease.

And I think it's a good way to determine blood pressure based on the temperature of your body and the speed of your heart.

It is not particularly accurate, it may be affected by environmental factors, or temperature factors, and many hospitals will not use electronic blood pressure monitors.

An easy way to identify the accuracy of an electronic sphygmomanometer.
