Precautions for purchasing an oxygen concentrator
11 Mar, 2022 15 Comment Leave Comments

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.

HEPA air purifier, HEPA filter screen
11 Mar, 2022 11,459 Comment Leave Comments
With the rapid development of the city, haze has also become an "urban disease". Everyone must know about the harm of haze to human body, and controlling haze is also a long-term project. In order to protect their health, most friends choose active defense, such as wearing anti haze masks when going out and using air purifiers at home. As the preferred anti haze product for thousands of families, the air purifier is favored by everyone for its efficient purification effect, but the air purifier is by no means a product that doesn't care when the switch is turned on. If you want to use it well for a long time, you have to know HEPA filter screen.
What is HEPA filter? HEPA (high efficiency particulate air filter), which means high efficiency air filter in Chinese, is a filter screen that meets the HEPA standard. For 0.1 micron and 0.3 micron, the effective rate reaches 99.7%. The characteristic of HEPA screen is that air can pass through, but small particles cannot pass through. It's PM2 5 killer can also capture molds, bacteria and viruses. It can be used in areas with poor air environment to maximize the protection of users' respiratory health.
It can remove particles with a diameter of less than 0.3 microns (1 / 200 of the hair diameter) with a removal efficiency of more than 99.97%. It is the most effective filter medium for pollutants such as smoke, dust and bacteria. If there are relatives who smoke at home, it is necessary to choose HEPA filter air purifier in order to protect the next generation from the harm of second-hand smoke.
HEPA can be divided into five materials: PP filter paper, glass fiber, composite PP pet filter paper, melt blown polyester non-woven fabric and melt blown glass fiber. Although the materials are different, they all have one thing in common: large wind resistance, large dust capacity and high filtration accuracy. In addition, there are three HEPA high-efficiency filters. One is super HEPA high-efficiency filter, which can purify 99.9995%. One is the antibacterial high-efficiency air filter without partition, which has antibacterial effect and prevents bacteria from entering the clean workshop. The other is the sub HEPA high-efficiency filter screen, which is cheap and used in the purification space with low requirements before. For our commonly used air purifiers, there are many filters with the latter two. After all, you get what you pay for.
In order to filter the air purifier efficiently for a long time, you must be able to maintain the HEPA filter screen. If there is no specific indication, it cannot be washed, but under the current situation of serious indoor air pollution in China, the longest service life of HEPA filter screen is generally only 3 months or less, which means that HEPA filter screen needs to be replaced frequently. Although the replacement cost of HEPA filter screen is high, and its service life can be extended to a certain extent by cleaning with a vacuum cleaner, if the generally white HEPA filter screen surface has tended to black, it is recommended to replace it as soon as possible in order to ensure air filtration effect and health. Moreover, the HEPA filter screen has been produced on a large scale, and the cost and price are constantly declining. It is still very convenient to replace the filter screen.
In short, the key role of HEPA filter screen for air purifier is to effectively filter PM2 5 and other harmful gases can also capture molds, bacteria and viruses, filter second-hand smoke and harmful micro particles in the air, and protect users' respiratory health. It is an indispensable and important part of the air purifier. However, it can not be used in the kitchen, because oil fume will accelerate the loss of HEPA filter screen, and it can not be used in the environment with particularly strong cigarette smell and poor air circulation (such as mahjong Hall). Cigarettes will greatly shorten the service life of HEPA. If it is an ordinary family to prevent haze and purify the air, the HEPA filter screen can be properly maintained according to the above methods. Under normal circumstances, it can be used for several months without changing. It not only saves money, but also purifies the air and protects the respiratory health of the whole family. It is worth choosing for users who want to purify the respiratory environment.

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 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.
