9 key points for measuring blood pressure
Many people have not really learned about measuring blood pressure and consider it a small matter, but many people cannot measure it after taking half a day. Below are 9 key points for measuring blood pressure! Remember to bookmark it!
1. Three preparations before measuring blood pressure
① Within half an hour before measuring blood pressure, smoking, drinking coffee, and holding urine should be prohibited to allow the body to "calm down".
② According to the latest Chinese Guidelines for the Prevention and Treatment of Hypertension (revised in 2018), blood pressure in the left and right upper arms should be measured at the initial diagnosis, with the side with the highest blood pressure reading as the upper arm for measurement.
③ Find a chair with a backrest to sit on, with your arms flat on the table; Try to keep your arms at the same level as your heart.
2. Do not take three blood pressure measurements
① Don't speak, don't move casually, speaking and moving randomly can lead to inaccurate blood pressure measurement.
② Don't cross your legs, this position can also cause blood pressure to deviate from the true blood pressure;
③ Relax, don't be nervous. Any tense emotions can lead to an increase in blood pressure, so many people go to the hospital to have their blood pressure measured high, and when they return home, their blood pressure is normal. In this case, it is recommended to use the one measured at home as the standard.
3. Three people who know after taking blood pressure measurements
① Measure at least twice and take the average value. If the difference between the two measurements is significant and exceeds 5mmHg, it can be measured again. Measure three times and take the average value. If the blood pressure is between 120/80mmHg, please continue to maintain a healthy blood pressure.
② If the blood pressure exceeds 140/90mmHg, it indicates that the control is not ideal. You need to find the cause and a doctor.
③ If the blood pressure is below 90/60mmHg, it indicates that the blood pressure is a bit low. Under the guidance of a doctor, antihypertensive drugs should be reduced or adjusted accordingly. The harm of hypotension is also significant.
For people with hypertension, it is important to develop a habit of monitoring blood pressure.
Ultraviolet air purifier
Ultraviolet air purifier is mainly used in families. It is a necessity for household disinfection and sterilization.
Function of ultraviolet air purifier
Adsorb PM2 in the air 5、PM0. 3 and other micro dust and various bacteria. In insufficient sunshine or haze days, Midea air purifier can automatically capture dust, bacteria and other particles in the air after air flow through air circulation, and completely adsorb the particles on the imported h13-hepa filter screen.
The unique UV lamp sterilization device of the air purifier can decompose and kill the bacteria blocked on the filter screen after the air flows, greatly reducing the secondary pollution caused by bacterial residue.
The UV device has a wavelength of 240 ~ 280 nm (about 254 has the strongest bactericidal power). The UV at this wavelength has a strong bactericidal effect.
Purification: release the purified air, kill the bacteria and harmful micro dust in the air, and release the air beneficial to the human body to achieve the purification effect.
Precautions for purchasing an oxygen concentrator
With the increasing awareness of health among people, various medical devices are becoming more and more well-known, among which the home oxygen concentrator is a relatively popular type of home medical device. The main group of people who need home oxygen concentrators are middle-aged and elderly people, and the actual buyers are often the children of the elderly. So, how can I buy a satisfactory oxygen concentrator for my parents?
Firstly, the oxygen concentrator should have a high-definition electronic display screen and be easy to operate. You should know that many elderly people have poor eyesight. If the text on the screen is too small or not clear enough, it will bring great difficulties to parents and the user experience will be very poor. Just starting up and using it will take a lot of time. In addition, the functional design should not be too complex. The main and core function of an oxygen concentrator is oxygen production. If there are too many fancy functions, it will make the operation more complex and also unfriendly to the elderly.
Common knowledge of using oxygen concentrators
What is the best time period for oxygen absorption?
Half an hour after meals and before going to bed at night, the body's blood oxygen saturation is low, and oxygen inhalation can supplement oxygen concentration.
After meals, due to frequent gastrointestinal peristalsis, blood oxygen will preferentially tilt towards the digestive organs, leading to a decrease in blood supply to other organs and an increase in the burden on the heart.
Because cardiovascular diseases usually occur late at night and early in the morning, oxygen before bedtime can effectively prevent the occurrence of cardiovascular diseases.
Moreover, oxygen inhalation has a sedative effect, and taking a little before bedtime can help you sleep soundly.
How long does each oxygen inhalation last?
The frequency and duration of oxygen inhalation vary from person to person. For people with lung diseases, it is recommended to continue low flow oxygen inhalation every day, specifically 2-3 liters per minute. If the situation is more serious, the oxygen output per minute needs to be adjusted to 5 liters. Of course, for this type of person, the specific situation must be followed by medical advice.
