Blood pressure meter is a device that measures blood flow pressure.Pressing air pressure on the local arteries, and then observing how much pressure is applied to stop the fluctuations of the local arteries.Therefore, the air pressure added represents the pressure of blood flow.So, how to use blood pressure meters?Which blood pressure meter is more accurate?
How to use blood pressure meters
1. Keep the room quietly. Before the measurement, the subject must relax. It is best to rest for 20-30 minutes. Empty bladder, do not drink alcohol, coffee and strong tea, and stop smoking.
2. Patients can take a sitting or horizontal type, with both feet flat, and their elbows and forearms are placed in a position that is about parallel to the heart.Let the patient take off the sleeves and expose the upper arm. If the sleeves are thin and wide, they can be rolled up to the armpit.
3. Open the blood pressure meter box, put it in the stable part of the patients limbs, and make the mercury column vertically until zero.
4. When the blood pressure meter is wrapped, the air in the air sleeves is squeezed out first, and then entangled with 2 to 3 cm on the joints of the right upper arm, not too loose or too tight.After touching the brachial beating in the inside of the elbow nest, the hearing of the auspiciousness is placed on the aeor artery, and the pressure was puzzled.
What kind of blood pressure meter is good
What kind of blood pressure meter is good, or according to the actual situation of consumers.Regardless of the blood pressure meter, it is important to choose the one that suits you. It is generally no problem to operate the correct operation when using the instructions.It should be noted that different blood pressure meters have applicable people and people who do not apply. The mercury sphygmomanometer is generally not suitable for patients with poor hearing or inability to hear.Patients with electronic sphygmomanometer wrist -type wrist -type patients with blood circulation, diabetes, hyperlipidemia, hypertension, arteriosclerosis, and peripheral cycle disorders are recommended to have the above -mentioned users and elderly people to choose upper arm electronic sphygmomanometers.The blood pressure meter blood pressure meter is not suitable for elderly people with vision and weak listening.
The mercury blood pressure meter is a relatively professional sphygmomanometer. It is also a blood pressure meter equipped with major hospitals and clinics. This blood pressure meter can directly show the measured blood pressure directly with the millimeter mercury, and the measurement is very accurate and reliable.Although the price of this blood pressure meter itself is relatively low, improper use can easily cause the mercury column to rupture and the problem of mercury leaks. It is dangerous. It is not recommended to use family use, and it also needs to use the auscultation.
Electronic sphygmomanometer is a relatively popular sphygmomanometer in the market. It is very popular with households. There are two types of upper arm and wrist type.This blood pressure meter is relatively simple in operation, it is easy to carry, complete, and more prices, suitable for different family choices.It can show parameters of multiple blood pressure measurement values ??such as diastolic pressure, systolic blood pressure, pulse pressure, average arterial pressure, and pulse rate.
Blood pressure gauge blood pressure meter, clinically called hydrophilicide, springs, springs, mainly uses the pressure pump to operate pressure.Small volume, easy to carry, is suitable for mountaineering, travel and work.However, as the number of applications increases, the accuracy of the results will be affected due to the change of spring traitors, so it is necessary to calibrate regularly with the standard mercury column blood pressure meter.
Which test is more accurate?
1. Different people should choose according to their personal circumstances. For those who often travel, it is recommended to choose to carry more convenient wrist electronic sphygmomanometers to use differences and use in travel.However, patients with severe vascular sclerosis or vascular calcification, as well as patients with diabetes, hyperlipidemia, hypertension and other patients with blood obstacles and vascular lesions are not suitable for using wrist -type and finger electronic sphygmomanometers.precise.The blood pressure gauge has been used very little clinically, and it is not recommended to buy it.Mercury blood pressure meter maintenance is more difficult and can be purchased according to needs.
2. Be sure to choose a good brand of blood pressure. The product instructions should have a production license number and detailed explanation of the correct way of use.If you do not understand the correct use of the product, it will also affect the correctness of the measurement result.
3. Look at the duplicability of the measurement results, repeat the blood pressure several times according to the correct use of the product manual, and see the average value of the result and the error value of each measurement.The error is too large, indicating that the products repetitiveness is not good.
4. Look at the correctness of the measurement results, compare the results measured on the same blood pressure on the same blood pressure, and look at the error value of the results.If the error is not too large, it can be used as a reference in my own measurement in the future.
