Blood pressure is a very important test for our patients with kidney disease. Well controlled blood pressure plays a vital role in protecting our kidney function.
But many people are not clear about their blood pressure, let alone what range they should control their blood pressure! I have a lot of responsibility for health. Today, follow Sasha to learn!
Why is blood pressure control so important for kidney protection?
We can imagine that the blood flows in the blood vessels, and the blood has an impact on the blood vessels. The higher the blood pressure, the greater the impact on the blood vessels. If the blood pressure is always high, it will cause damage to the blood vessels over time.
As we all know, the most important part of the kidney is the glomerulus, which can be simply understood as a ball formed by small blood vessels. High blood pressure will harm our precious little ball in all aspects.
The reason why glomeruli are precious is that they are not renewable and lose one less. (To be a digression, renal puncture only takes out about 30 of millions of glomeruli)
How much blood pressure is required for patients with kidney disease?
Blood pressure is generally read as high pressure versus low pressure (the professional term is systolic pressure versus diastolic pressure). For example, the doctor wrote 130/80mmHg in the case book, and the number 130 in front is high voltage; The latter 80 is low pressure, and the blood pressure reading of this is 130 to 80.
Requirements for 24-hour urine protein less than 1g: high pressure should be less than 130/80mmHg than low pressure; If proteinuria is greater than 1g, the requirements are more stringent: 125/75mmHg or less; However, the target value of dialysis patients is higher: 140/90 before treatment and 130/80 after treatment.
If you don't know your blood pressure, you'd better take it.
It's difficult to measure blood pressure again
(I)
Many people are nervous when they see people wearing white coats when they enter the hospital. The measured blood pressure will be higher than the actual blood pressure.
Although I am a doctor myself, I also have this psychological barrier. Every time I see another doctor taking my blood pressure and measuring my heart rate, I am very nervous. My heart rate is often more than 100, and my blood pressure is always at the upper limit or even above the upper limit. I can't slow down.
This is called white coat hypertension! In order to avoid white coat hypertension, you can let your family or yourself measure it at home, and rest for five minutes in a calm state, which is most suitable for your actual situation.
(II)
If you have just started the treatment of hypertension or have just adjusted the dosage of medication, you should measure it once a day after getting up, before meals and before going to bed, and then reduce the frequency until the blood pressure is stable and up to the standard for at least one week. If necessary, the doctor will also require 24-hour ambulatory blood pressure monitoring. Patients with good blood pressure control will be tested 1-2 times a week at the time of their daily high blood pressure, usually at the time of morning rise.
(III)
In the selection of sphygmomanometers, there are electronic and mercury sphygmomanometers. Electronic, generally speaking, the best choice is the upper arm sphygmomanometer; Although wrist sphygmomanometer is more convenient and saves taking off coat in winter, it is not as accurate as upper arm sphygmomanometer. There are finger sphygmomanometers on the market, which are even more inaccurate and not used as a reference.
It is better to check the electronic sphygmomanometer when it is bought, and let the medical staff who can use the mercury sphygmomanometer measure it several times to check the accuracy of the electronic sphygmomanometer.
Mercury sphygmomanometer is generally used by doctors, but it is not difficult to operate. As long as we master the method, our patients can also measure it at home.
4 Operation method of mercury sphygmomanometer
1/First, put the sphygmomanometer at the same level as the measured person's heart, and turn on the sphygmomanometer; The switch is at the place where the thumb is pressed.
2/Then wear the cuff 2-3 cm above the elbow socket, about the looseness of 1 or 2 fingers
3/Put one end of the stethoscope on the ear and the other end on the inner side of the elbow socket. If you touch it with your hand, there is an obvious pulsation of the artery, that is, stick the stethoscope to the pulsation of the artery.
4/Turn on the ball switch and start to pinch the ball for air. You can see that the mercury starts to go up. If you don't see the mercury moving up, either the mercury switch in the first step is not turned on, or the ball switch is not turned on.
5/Pinch the mercury to 150 when the sound is heard at 130.
6/At this time, turn the ball switch down to let the mercury slow down. The falling speed can be controlled by practicing more times. As the mercury drops, you will begin to hear a thumping sound. The scale of the first sound you hear is high pressure, and the scale of the last sound you hear is low pressure. Look at the scale and your eyes should be level with the mercury.
7/Turn the sphygmomanometer aside every time you use it, take the mercury back and turn off the switch.
