Blood Pressure Monitor How To Choose
Blood pressure monitor is now sold on the market blood pressure measuring instrument is divided into mercury column blood pressure measuring instrument and electronic (no liquid) blood pressure measuring instrument two categories.
There are two ways to measure:
Use the microphone to remove the sound from the blood flow (this sound is called Korotkoff sound). As with hospital measurements (mercury-based sphygmomanometer), the doctor listens with the stethoscope.
Oscillation method (Oscilloscope method): to obtain blood flow occurs when the vibration changes, the general electronic sphygmomanometer measured by this method.
how to choose
The use of electronic blood pressure measuring instrument self-measurement of blood pressure is accurate in patients with hypertension, especially in many elderly people concerned about the problem. Often hear people talking about electronic blood pressure measuring instrument are not allowed, the value of each measurement are not the same. So, how should you choose an electronic blood pressure gauge?
1. The type of electronic blood pressure measuring instrument
Electronic blood pressure measuring instrument from the measurement there are two: arm and wrist. These two electronic blood pressure measuring instruments are suitable for healthy people. But to note that the wrist of the electronic blood pressure measuring instrument does not apply to patients with blood circulation disorders. Diabetes, hyperlipidemia, hypertension and other diseases will accelerate the arteriosclerosis, causing patients with a slight circulatory disturbance, these patients with wrist blood pressure and upper arm blood pressure measurements vary widely. It is recommended that these patients and the elderly choose arm blood pressure measurement instrument.
2. The market for electronic blood pressure measuring instrument for the crowd
Electronic blood pressure gauges on the market are basically qualified to measure blood pressure more accurately, but different types of different brands of electronic blood pressure measuring instrument in the blood pressure measurement range and the applicability of the affected population is different of. For example, some electronic blood pressure measuring instrument systolic blood pressure (high pressure) measurement limit of 26.7kPa (200mmHg), diastolic blood pressure (low pressure) measurement limit of 20kPa (150mmHg), and some electronic blood pressure measuring instrument is greater than the upper limit of the above; For example, the intelligent electronic blood pressure measuring instrument than the non-intelligent electronic blood pressure measuring instrument in the applicable population to be wider. The electronic blood pressure measuring instrument measures whether blood pressure is accurate or not. It is accurate to measure blood pressure within the range of blood pressure measurements allowed by the electronic blood pressure gauge and within the applicable patient population. Beyond the scope of application of electronic blood pressure measuring instrument, the blood pressure measurement is not allowed or may not be measured out. For example, some electronic blood pressure measuring device cuff use range of 22 ~ 32cm, the user's arm circumference is greater than or less than the scope of cuffs, the blood pressure measurement may be measured inaccurate. Visible cuff size on the accurate measurement of blood pressure have a greater impact. Due to the limits of the electronic blood pressure measuring instrument, there are always people who can not use it to measure blood pressure, such as weak veins, high blood pressure or too low, and so on. In other words, the electronic blood pressure measuring instrument is not all people apply, so the purchase must choose their own electronic blood pressure measuring instrument.
3. Whether the measurement results of the electronic blood pressure measuring instrument are accurate
For this problem can be from two aspects: First, people's blood pressure changes in a day is relatively large. Strictly speaking, every moment of blood pressure is not the same, it is with the person's mental state, time, season, temperature changes and the location of the measurement (arm or wrist), position (sitting or lying) different And change. Therefore, each measurement of blood pressure is a normal phenomenon. As a result of tension and anxiety, people in the hospital measured systolic blood pressure (high pressure) is generally higher than at home, this phenomenon is called white coat hypertension. That people in front of the doctor will unknowingly produce a certain degree of anxiety, tension and mental stress, resulting in increased blood pressure, at home is more relaxed, the amount of blood pressure is low, and this is the true reflection of human blood pressure The Second, the measurement method is not correct. Measure should pay attention to the following 3 points: First, the height of the cuff to the heart with the same height, and the cuff of the hose should be placed on the brachial artery pulsation point, the bottom of the cuff should be higher than the elbow 1 ~ 2cm, With the rolling of the elastic to be able to just insert a finger is appropriate; followed by the measurement must be kept quiet before about 10 minutes, in addition to the measurement interval should not be less than 3 minutes, and the measurement of the location, Consistent. Do this 3 o'clock, it should be said that measured blood pressure is accurate, objective.
