How to use a sphygmomanometer

How to use a sphygmomanometer, there are elderly people at home, or at home with blood pressure, relatively low blood pressure, abnormal people. Often need to measure blood pressure people, home certainly have a sphygmomanometer, because this is more relatively convenient, can be more quickly and conveniently their own blood pressure, let's look at the use of the sphygmomanometer

The use of the sphygmomanometer 1

1, measuring blood pressure before the 'preparation

Let the patient sit in the seat or bed rest for a few minutes, then expose the right arm and always be to the right arm, and then the right arm, and then the right arm, and then the right arm. Then expose the right arm and to be exposed until the shoulder, and then straighten the elbow, palm up flat.

2. Adjust the scale of the mercury sphygmomanometer

Place the mercury sphygmomanometer on the table or on the bed, and then make the scale of the sphygmomanometer "0" point, and the patient's heart in the same plane.

3, the mercury sphygmomanometer binding

The sphygmomanometer cuff should be wrapped around the patient's upper arm, and the lower edge of the cuff should be from the elbow nest 2 cm to 3 cm, should not be too tight or too loose.

4, stethoscope wear

The stethoscope will be worn, and then the patient's elbow in the area of the brachial artery, and put the stethoscope on the brachial artery beat, this time you can hear the artery "dong dong" beat sound.

5, the measurement of systolic blood pressure

First, tighten the balloon and then to the cuff to pump, the pressure should be added to the brachial artery can not be heard until the sound of the brachial artery beat. Then slowly release the valve to reduce the pressure, and pay attention to the scale pointed by the mercury column until the first beat is heard. Observe the scale of the mercury column at this point, which is the systolic pressure.

6, diastolic pressure measurement

After the first beat is heard, the pressure continues to decrease gently, until the arterial beat gradually increases to suddenly become soft and weak, and then observe the scale pointed to by the column of mercury, the scale for the diastolic blood pressure (note that it is not the sound of the beat completely disappeared).

Normal blood pressure is 80-120 mmHg, but it varies according to gender, age, external environment, and your own factors.

How to use a sphygmomanometer2

Traditional sphygmomanometers

Because it is manual, it is easy to have bias in the process of measurement, but for those who have been trained professionally, the error is small, and in the clinic, it is based on the measurement of mercury sphygmomanometer.

Electronic sphygmomanometers are more convenient to operate

The application of simple oscillometric electronic sphygmomanometers for blood pressure monitoring has a positive significance in improving the level of health care for the public.

The mercury column sphygmomanometer used by doctors in hospitals is only a tool for pressure measurement, and the idea that a mercury column sphygmomanometer is an accurate sphygmomanometer is one-sided, because a mercury column sphygmomanometer is only a manometer, and the focus is on the doctor's auscultation through the stethoscope. Currently, the use of mercury column sphygmomanometers is generally banned in developed countries internationally in favor of more accurate electronic manometers (meters).

Mercury sphygmomanometer more accurate, and do not use batteries, more cost-effective, but the use of more trouble, must be measured by others to help can, but also need to use the stethoscope, the measurement of the operator's manipulation of a certain requirement, but now many electronic sphygmomanometers are also very accurate, easy to use, press a key on it, and can even give themselves to their own measurements, the shortcomings of the accuracy of the sometimes sometimes by the The disadvantage is that sometimes the accuracy is affected by the battery voltage, and you have to change the battery often.

In comparison, electronic sphygmomanometers are accurate and easy to use, while mercury sphygmomanometers are more accurate but require professional help, so more patients choose electronic sphygmomanometers.
