How to use a sphygmomanometer stethoscope
There are two main methods for noninvasive blood pressure measurement: auscultation and oscillometry. Auscultation, also known as Coriolis method, is to tie the cuff of a manometer (commonly known as sphygmomanometer) to the pulsating position of the brachial artery in the upper arm, inflate and pressurize the brachial artery to deflate it, and then deflate and decompress it. With the decrease of external pressure, blood flow reopens blood vessels and makes a sound with the same rhythm as the heart beating. This is the Coriolis sound. When the "first sound" is detected by a stethoscope, the external pressure displayed by the manometer is recorded as systolic pressure, and when the "last sound" is recorded as diastolic pressure. This method was put forward by Russian doctor Korotkov in 1905, and it was quickly recognized by the international medical community, and it was called Kirchhoff sound method. Blood pressure mentioned in all international documents, clinical manometry, hypertension grading standards, textbooks, etc. Refers to blood pressure measured according to Coriolis sound method. This is the international gold standard for noninvasive blood pressure measurement, and it is also the clinical standard for testing the accuracy of all noninvasive sphygmomanometers. The detection of oscillometric electronic sphygmomanometer is also carried out according to this standard.
Auscultation includes manual auscultation and automatic auscultation. Artificial auscultation sphygmomanometer mainly includes mercury sphygmomanometer and sphygmomanometer. There will be errors in hearing, vision and subjective judgment when operated by professionally trained personnel. Automatic auscultation technology is difficult because of the great difference between human bodies. Automatic auscultation sphygmomanometer is rarely seen in the market, which will be the mainstream direction of sphygmomanometer development. Because it solves the complexity of artificial auscultation and the inaccuracy of oscillometric diagnosis. At present, sphygmomanometer with automatic auscultation has been seen.
Electronic sphygmomanometer chooses arm type or wrist type.
When choosing a sphygmomanometer, we should consider the user's situation.
① For ordinary people, both arms and wrists can be used, and wrist measurement is convenient.
② Most middle-aged and elderly people (patients with diabetes, hyperlipidemia and hypertension). ) use your arm posture. For those patients with high blood viscosity and poor microcirculation, compared with the results measured by mercury sphygmomanometer, the error of blood pressure measured by wrist and finger will be great. The national hypertension guide unanimously recommends the upper arm electronic sphygmomanometer certified by international standards.
A diet that lowers blood pressure
Although drug therapy has a significant effect on reducing hypertension, long-term drug use will also cause dependence on it, which is a secondary harm to human health. Besides medication, daily diet health care is also an important way to reduce hypertension. Some foods can effectively stabilize high blood pressure and let patients live a healthy life. Such as celery, chrysanthemum, amaranth, yam, leek, day lily, shepherd's purse, spinach and other vegetables; Apples, watermelons, fresh plums, lemons and other fruits; Some fungi, such as Ganoderma lucidum, Auricularia auricula, Auricularia auricula and Lentinus edodes, are essential for patients with hypertension on the table. Patients should also eat more foods containing high-quality protein and vitamins. Such as fish, milk, lean meat, eggs, beans, bean products and so on. Eat more foods containing potassium in the diet.
Here are some low-cost, simple-to-make hypertension diets (the following information is for reference only, please consult your doctor for details):
(1) Celery porridge: celery 120g, japonica rice 250g. Wash celery, cut into six sections, and wash japonica rice. Put celery and japonica rice into a pot, add appropriate amount of water, boil with strong fire, then stew with slow fire until the rice is rotten into porridge, add a little salt and monosodium glutamate, and stir well.
(2) Chrysanthemum porridge: chrysanthemum powder 15g, japonica rice 100g. Take off the stems of chrysanthemum, steam them in a cage, take them out to dry in the sun or in the shade, and then grind them into fine powder for later use. Wash the japonica rice, put it in a pot, add appropriate amount of water, boil it with strong fire, then cook it with slow fire until it is half cooked, add chrysanthemum fine powder, and continue to cook it with slow fire until the rice is rotten into porridge. Dinner twice a day.
(3) Mung bean seaweed porridge: Mung bean and kelp 100g, appropriate amount of rice. Chop kelp and cook it with two other ingredients to make porridge. Can be eaten as a dinner for a long time.
What fruit does hypertension eat?
Pregnant women are actually quite afraid of getting hypertension during pregnancy, especially those with a family history of hypertension. When pregnant women suffer from hypertension, they may show mild dizziness, and in severe cases, nausea, vomiting and coma may endanger the health of mother and baby. To this end, pregnant women with hypertension can eat some fruits that lower blood pressure during pregnancy.
1, an apple rich in potassium salt
If hypertensive patients consume too much salt, their blood pressure will continue to rise, and apples are rich in potassium salt, which can eliminate excess sodium salt in the body. In addition, apples can also prevent the increase of cholesterol in blood and reduce the sugar content in blood.
2. Kiwifruit with enhanced immune function
Eating some kiwifruit helps to prevent the continuous rise of high blood pressure.
3, diuretic antihypertensive watermelon
Watermelon should not be eaten more, but eating a little watermelon can help pregnant women diuresis, which can reduce blood fat and blood pressure.
4. Persimmons rich in VC
Persimmons contain more vitamins than ordinary fruits, and the VC contained in them can lower blood pressure and protect the cardiovascular system.
