for those poisoned by harmful gas, they should be carried to the fresh airflow roadway or ground immediately, and first aid measures should be taken according to the poisoning situation
carbon monoxide poisoning. Carbon monoxide poisoning, shallow and shortness of breath, loss of consciousness when the cheek and body erythema, pink lips. Artificial respiration or oxygen delivery with hematoxylin apparatus can be used for the injured. 5% ～ 7% carbon dioxide can be infiltrated ring oxygen infusion to excite the respiratory center and promote the recovery of ventilator function
hydrogen sulfide poisoning. In addition to artificial respiration or oxygen delivery, cotton ball and handkerchief soaked with chlorine solution can be put into the mouth. Chlorine is a good detoxification of hydrogen sulfide
sulfur dioxide poisoning. As sulfur dioxide generates sulfuric acid when it meets with water, it has a strong stimulating effect on the respiratory system and may burn in severe cases. Therefore, in addition to artificial respiration or oxygen delivery with hematoxylin apparatus, the poisoned should be given milk, honey or gargle with soda solution to rece the irritation
nitrogen dioxide poisoning. The degree of lung injury depends on gas concentration and inhalation time. After exposure to more than 150 mg / m3 of nitrogen dioxide for 3-24 hours, cough, bloody sputum, shortness of breath, fever, weakness, nausea and headache may occur, and rales and wheezes may be heard in the lungs. Severe dyspnea, cyanosis, etc. They should leave the scene immediately, breathe fresh air, keep the respiratory tract unobstructed, inhale oxygen, and provide noninvasive or invasive mechanical ventilation when necessary
biogas poisoning. For biogas emergency measures, the poisoned person should be quickly removed from the scene (rescue personnel must wear aerobic protective mask) and sent to "120 & quot; Call for help; Take oxygen and send it to hyperbaric oxygen chamber if possible; Artificial respiration; Prevention and treatment of brain edema
ammonia poisoning. Remove the patient from the poisoning site immediately. Oxygen, artificial respiration and injection of respiratory stimulants. Keep respiratory tract unobstructed. Get the aspirator ready. 3% boric acid can be used as atomization inhalation for mild patients. Prevention and treatment of pulmonary edema. Maintain oxygenation. Including nasal catheter oxygen, mask oxygen, etc., use positive pressure ventilation when necessary. Oxygenation maintained the target oxygen saturation above 93%. For eye burns, rinse with water or 3% boric acid solution for at least 15 minutes. For those with skin burns, wash the skin immediately with water, 3% boric acid, 2% acetic acid, or vinegar to neutralize ammonia and eliminate burns. If there are blisters, exudates and ulcers on the skin, wet compress with 2% boric acid and apply with chemical burn oil. Large area deep burns need special treatment
carbon dioxide poisoning. Suddenly into a high concentration of carbon dioxide environment, most people can in a few seconds, e to respiratory center paralysis, suddenly fall to the ground and die. Some people can feel dizziness, palpitation, delirium, convulsion and coma. During the first aid, the carbon dioxide poisoning should leave the scene quickly and breathe fresh air or oxygen. The patient's collar should be loosened to keep the respiratory tract unobstructed; keep warm; Pay attention to observe the state of consciousness and monitor vital signs. For patients with respiratory and cardiac arrest, artificial respiration, external cardiac compression or open chest massage should be insisted. Patients with dyspnea were injected with respiratory stimulants. Hyperbaric oxygen therapy

6. In the practice of blockchain + ecation application, Qingda century has already explored its own mode.
7. For the century of the Qing Dynasty, ecation chain is an opportunity. Ecational resources and ecational projects are not only limited to China, but also have a great impact on the development of the global ecation instry and the distribution of ecational resources.
8. The people's vision is clear. The ecation chain can share the ecational value. We can realize the open and all-round sharing of ecational value through the system constructed by the ecation public chain, "new media smart machine" (offline) and "points exchange mall" (online).
9. At present, all the ecation chains are still in the trustworthy ecation background, credits and recruitment. The brain chain focuses on the essence of Ecation - knowledge.
10. Internet plus ecation is an important part of the national strategy "Internet plus", and is a pioneer and a new leader in the reform and development of ecation. It is also a powerful engine to speed up the process of ecational modernization. Internet plus ecation must Internet and ecation, and grasp the essential characteristics and development trend of Internet plus ecation, and grasp the leading and initiative of "Internet plus ecation". Internet plus ecation, Internet / ecation, is the essential feature of BR + > 1 /
Second, innovation driven“ "Internet plus ecation" is the embodiment of the Internet thinking on the whole and part of ecation innovation, so that the quality of ecation has undergone qualitative changes, to achieve a level leap. 2] One is to strengthen the support of technology for ecational innovation. For example, graphics and image technology, search technology and social network promote the further development of Internet ecation form, and new technologies such as digitization, virtual world, cloud computing, online video, topic recording, mobile teaching bring the formation of ecation and teaching interactive innovation mode, etc. The second is to promote the development of ecational maker space. It can give full play to the advantages of network open innovation, gather network technology resources, create various types of ecation and teaching innovation space, and provide students with a platform for innovative learning and entrepreneurship experiment. At present, in all kinds of schools at all levels where reform and development take the lead, mass innovation space is springing up in large numbers, becoming a scenic spot of ecation modernization. Third, form open and sharing innovation. Internet technology provides convenience and possibility for the opening and sharing of innovation. The innovative ideas and ideas of ecation subject carry out innovation cooperation and integration through the Internet, so that the participants can share the results, and the innovation points of ecation and teaching can rapidly spread and develop into the line and surface of innovation
thirdly, optimize the relationship“ "Internet plus ecation" breaks the original relationship structure, optimizes and restructures it, and makes the relationship between teachers and students, ecational institutions and learners change radically and upgrade to a higher level. Change the traditional connotation of organization and cooperation, make the boundary between the real world and the virtual world fuzzy; Let users have the right to learn, share widely and exchange information symmetrically; So that people's roles can be exchanged and changed, and the wisdom of the public can be truly integrated to carry out innovation and entrepreneurship
Fourth, expand opening up“ Internet plus ecation has made ecation go out of school, across regions, countries and the whole world, and has achieved real openness. Khan Academy is a typical case. In 2007, Khan founded the Khan Academy to enable more people to enjoy quality teaching. After two years of efforts, he quickly gathered 10 million students and became the largest "school" in the world
fifth, it is more ecological. The ecology of ecation is characterized by pluralism, diversity, nature, evolution, graalness and qualitative change“ "Internet plus ecation" makes the above characteristics of ecation more prominent and more operational. Because the advanced technology can pay more attention to each indivial student, present the learning content more diverse and more in line with the needs, and the roles and roles of teachers and students will also be profoundly changed. The students' dominant position and creativity will be more fully expressed, and the learning methods will be more indivialized and subtle, making learning ubiquitous and omnipotent. Teachers are mainly instructors and teachers The guide is the care and Inspiration of students' life
two, Internet plus ecation development trend
first, growth orientation is manifested in two aspects of technology and region. Due to the rapid development of broadband technology and the rapid expansion of 4G commercial scope, intelligent terminals have joined the field of ecation, which makes teaching live interaction realized and popularized. Students don't need to sit next to computers or access WiFi. They can learn anytime and anywhere by using mobile phones and tablets through 4G network. According to China Mobile Internet development report (2015), the number of mobile Internet users in China reached 557 million in 2014; In 2015, 839 million users used mobile phones to access the Internet. The proportion of users who use mobile phone to watch videos is increasing. This provides a broad and solid foundation for "Internet plus ecation". On the one hand, North America and Western Europe are in the leading position; On the other hand, Asian countries are developing rapidly and will become strong competitors. The study found that the number of primary and secondary school students in Asia is more than 600 million, more than that in North America and Western Europe combined. It is predicted that Asia will account for more than half of the 200 million people aged 25-34 who have received higher ecation in the world by 2020. The market demand for online learning procts in Asia continues to heat up. By 2018, Asia is expected to account for 23% of the global Internet ecation market[ 3]
Second, technology orientation, which mainly refers to big data. Big data not only has a profound impact on human proction and life, but also has entered into ecation, causing changes in ecation. In walking with big data: the future of learning and ecation, Viktor Myer Schoenberg pointed out that big data can help realize flexible schooling, personalized teaching and family learning to the maximum extent. Big data can be targeted to provide students with a variety of required courses to help teachers and ecational institutions improve the pertinence and effectiveness of student guidance
thirdly, the main body orientation mainly refers to the deep combination of big Internet companies and ecational institutions“ Internet plus ecation needs the initiative of both sides and the ecation, especially the Internet side. They have the initiative in the early stage of their development, and their active participation is the key. This is true. In the global Internet plus ecation development, Google, Microsoft, Internet, Alibaba, Tencent and other large companies are important pioneers and leaders. Google's "Google classroom" and Microsoft's "class notebook" are the ecational styles that lead the trend and the wind.
Fourth, service orientation, mainly focusing on K-12 and vocational ecation. In the future, the hot spots of Internet plus ecation are K-12 and occupation ecation. K-12 is the largest student group, and the content of ecation learning is the most. Therefore, the "Internet plus" space is bigger and the prospect is wider. Vocational ecation is related to people's career and living standards. More and more technical skills need to be learned and mastered, so there is a great demand for the market. Therefore, a large number of large investment projects or companies have emerged in the field of vocational ecation< In BR />2015, the guiding opinions issued by the State Council have upgraded the "Internet plus" action to the national strategy. "Internet plus ecation" has become an important indicator of the realization and upgrading of ecational modernization. According to the Ministry of ecation, in 2015, the national investment in ecation informatization reached more than 200 billion yuan. As of November 2014, 82% of primary and secondary schools in China have access to the Internet. Among them, 32% of primary and secondary schools have access bandwidth of 4-10 megabytes, 41% of primary and secondary schools have access bandwidth of more than 10 megabytes, 78% of primary and secondary school students are equipped with multimedia teaching equipment in the whole network, and 39% of ordinary teaching rooms are equipped with multimedia teaching equipment. China's "Internet plus ecation" has a good foundation and has become a powerful engine to speed up the modernization of ecation in China.
