First aid measures
On-site first aid
1. Let the patient leave the poisoned environment as soon as possible, move the patient to a place with good ventilation and fresh air, keep warm, and immediately open the doors and windows to circulate the air.
2. Patients should rest quietly to avoid aggravating the burden on the heart and lungs and increasing oxygen consumption after exercise.
3. Loosen the button, keep the respiratory tract unobstructed, and remove the mouth and nose secretions. If respiratory arrest is found, mouth-to-mouth artificial respiration should be performed immediately, and external cardiac massage should be performed.
4. Acupuncture treatment should be carried out immediately, and the acupoints are Taiyang, Lieque, Renzhong, Shaoshang, Shixuan, Hegu, Yongquan and Zusanli. Patients with mild or moderate poisoning can gradually wake up after acupuncture.
5. The poisoned patient who is unconscious must be carried out of the poisoned environment as soon as possible. In the shortest time, check the patient's breathing, pulse and blood pressure, and make emergency treatment according to these conditions.
6. Breathing and heartbeat stop, and artificial respiration and cardiac compression should be performed immediately.
7. Call 121 emergency service, and the emergency doctor will go to the scene to treat the patient.
8. Immediately inject 51 ml of 51% glucose solution intravenously and add C511~1111 mg of vitamin C.. Light and medium-sized patients can be used for 2 days, 1~2 times a day, which can not only replenish energy, but also dehydrate. Early application can prevent or alleviate brain edema.
9. After the condition is stable, escort the patient to the hospital for further examination and treatment.
11. Give oxygen immediately, and if possible, transfer to the hospital hyperbaric oxygen chamber for hyperbaric oxygen treatment immediately, especially for patients with moderate and severe gas poisoning, which can not only awaken the patients, but also reduce the sequelae.
11. Coma patients should be treated as coma patients.
Follow-up treatment
1. Insist on going to the park or balcony in the morning to do deep breathing exercises, chest-expanding exercises and Tai Ji Chuan for about 31 minutes every day, and light and medium poisoning patients should continue to do morning exercises for 7-14 days; Severe poisoning patients can do morning exercises for 3 ~ 6 months continuously according to the sequela, and do Wuqinxi, Tiebu Shirt, Baduanjin and so on.
2. Continue to take jinvita 1 ~ 2 pills a day for 7 ~ 14 days, or 1.1 ~ 1.2g of vitamin C, three times a day, or take vitamins B1, B6 and vitamin B complex in moderation.
3. Check the use of gas to prevent poisoning again:
a. Check whether the gas leaks, whether the installation is reasonable, whether the gas stove is trouble-free and whether the use method is correct;
b, whether the heating method in winter is correct, whether the gas pipeline is unblocked, and whether the indoor ventilation is good;
c, try not to use the coal stove for heating. If you use it, you must abide by the coal stove heating rules and don't be careless;
d, the water heater should be built in separate rooms from the bath, and the connection pipeline between the gas and the water heater should be checked regularly;
e, if you feel the smell of gas after entering the room, you should quickly open the doors and windows, and check whether there is gas leakage or a coal stove indoors, and do not ignite;
f, often wipe the cooker to ensure that the cooker will not cause human pollution. After using the gas switch, wash your hands with soap and rinse with running water. Install an exhaust fan or range hood in the kitchen;
g, be sure to use special rubber hoses for gas, not nylon, vinyl pipes or worn-out pipes, and check the pipeline access once every six months. Safety teaching plan for large classes in kindergarten "Prevention of gas poisoning" 2
Teaching objectives:
1. Make students fully understand what gas poisoning is, and never take it lightly, and understand and master the rescue method of gas poisoning.
2. Through this theme class meeting, improve students' awareness of preventing gas poisoning and form a good living habit.
3. Through this class meeting, let the students know what to do after a fire, and pay attention to how to prevent the fire at ordinary times.
4, learn how to emergency, self-help and protection.
Teaching emphasis:
1. Understand what gas poisoning is.
2, gas poisoning and fire rescue measures and emergency methods.
Teaching difficulties:
How to rescue gas poisoning patients?
Preparation before class:
1. Know whether there have been any gas poisoning incidents among your relatives and neighbors and how to rescue them.
2. Ask the students, what are you going to do if you encounter a gas poisoning patient or a fire?
Teaching procedure:
First, introduce a new lesson: What is gas poisoning? What is gas poisoning? When everyone went home, did they ask anyone they knew if there had been gas poisoning? How was it rescued at that time?
Second, learn the knowledge of gas poisoning:
1. Seasons and causes of gas poisoning
(1) Every winter, gas poisoning will happen if people are not careful when warming themselves or taking a bath with a water heater. (2) Because of the weather, all the windows are closed, which leads to air circulation and gas poisoning. (3) Due to the user's neglect, the valve of the gas bottle was not closed, which led to gas poisoning.
2. The process of gas poisoning We know that human blood is composed of red blood cells, white blood cells, platelets and plasma. The oxygen that people need in the process of life is brought to all parts of the human body by hemoglobin in red blood cells. Coal or charcoal will produce carbon monoxide gas-coal gas when oxygen is insufficient and combustion is incomplete. Carbon monoxide is very aggressive, and the concentration of 1.14% ~ 1.16% or above in the air quickly enters the blood stream, occupying all the red blood cells in the human body in a short time, clinging to the hemoglobin in the red blood cells, making it form carboxyhemoglobin, replacing the oxygenated hemoglobin formed by the combination of oxygen and hemoglobin under normal circumstances, making hemoglobin lose its function of transporting oxygen. The binding force between carbon monoxide and hemoglobin is 311 times greater than that between oxygen and hemoglobin. After carbon monoxide poisoning, human blood can not supply sufficient oxygen to tissues and organs of the whole body in time, and at this time, the oxygen content in blood drops obviously. The brain is one of the organs that need oxygen most. Once the oxygen supply is cut off, the oxygen in the body can only consume 11 minutes, which will soon lead to coma and life-threatening.
3. Symptoms of gas Carbon monoxide gas can combine with hemoglobin in human red blood cells, making hemoglobin lose its ability to carry oxygen, but people are poisoned. The symptoms in the early stage of poisoning are: dizziness, headache, dizziness, palpitation, nausea and vomiting, followed by the aggravation of the above symptoms, dizziness, lethargy, thin, fast and weak pulse, and decreased blood pressure. Finally, they often suffocate and die because of severe hypoxia.
4. First-aid methods If you find a patient with gas poisoning, you should first open the doors and windows immediately, move the patient to a place with fresh air and ventilation, and then inform the doctor. 3
Study purpose:
By learning the knowledge about gas safety, students can establish the concept of self-care and self-rescue, form the consciousness of self-care and self-rescue, and prevent some unnecessary accidents.
learning process:
1. Introduction to conversation:
Students live in a happy and warm family, and are cared for and cared for by their parents and family members. It seems that there is no danger. However, there are still many things in family life that need to be paid attention to and treated with care, otherwise it will easily lead to danger and accidents. In fact, there are always hidden dangers in our family, especially about the use of gas. We must always be vigilant.
gas is a kind of high-quality gas fuel, which has the advantages of cleanliness, convenience and energy saving, and plays an active role in improving people's living standards, promoting economic development and protecting the environment. Gas is also a flammable, explosive and toxic gas. If it is not used properly, it will also be dangerous and cause accidents.
Second, the knowledge of safe use of gas is taught
1) When gas appliances are working, people should not leave for a long time, in case they are blown out by the wind or doused by water overflowing from the pot, resulting in a large amount of gas leakage and a fire. (Explain with examples)
2) When using gas appliances (such as gas stoves and gas water heaters, etc.), indoor ventilation should be fully ensured, and enough oxygen should be maintained to prevent gas poisoning.
The specific questions involve:
1) How to identify gas leakage?
2) What are the symptoms of gas poisoning?
3) what measures should be taken for gas poisoning?
4) What are the hazards of stacking things near gas meters?
5) how to light the gas?
6) how to adjust the flame?
7) Maintenance of gas stoves
Third, let the students interpret some kitchen fragments, so that everyone can learn how to save themselves, find problems and take measures.
Fourth, through this theme class meeting, students learned the knowledge about gas safety, protected themselves and ensured the safety of their homes.
5. The class meeting will summarize the lesson plan "Prevention of Gas Poisoning" for large classes in kindergarten. 4
Teaching objectives:
1. Improve students' awareness of safety precautions through understanding gas poisoning incidents;
2. By analyzing the causes of gas poisoning, make students know how to save themselves in the face of gas poisoning;
3. Have a preliminary knowledge of gas poisoning prevention.
Teaching emphasis:
Understand the situation of gas poisoning and its treatment methods;
Teaching difficulties:
Treatment of gas poisoning;
teaching method:
combining teaching, discussion and demonstration.
Teaching strategy:
Group cooperative learning
Teaching process:
(1) Get to the point and understand the truth
Dear students, this semester we are about to face winter, which is often a period of high incidence of gas poisoning. If you are not careful, you may be in danger and cause an accident. In order to enhance students' awareness of safety precautions and improve our ability of self-care and self-rescue, we have prepared this class meeting on the theme of "Safety Education against Gas Poisoning".
(introducing the gas poisoning incident reported by our province and city recently)
Case of gas poisoning 1. xx News Author: Reporter
[Abstract] At 9 o'clock in the morning of August 9, a man was found dead in a black SUV in the middle section of Changling South Road in xx High-tech Zone, three or four days after his discovery. After the police of Garden Police Station of High-tech Branch rushed to the scene, they immediately pulled up warning tape around the vehicle. After forensic investigation at the scene, it was initially confirmed that the man had died and there was no obvious trauma on the deceased. After forensic identification, it was determined that the cause of the man's death was the unfortunate death of inhaling excessive carbon monoxide after turning on the air conditioner in the closed state of the car.
Case 2 of gas poisoning: xx, Shaanxi: Going home to attend a funeral accident, five people in one room were poisoned and knocked down (playing the news report video at that time)
Case 3 of gas poisoning: 11 primary school girls in Shaanxi died of gas poisoning (playing the news report and related videos at that time)
(2) Telling a new lesson:
1. Topic: gas poisoning safety education blackboard
2.
3. Ask students: Raise your hand and answer.
4. Teacher's comment: Gas poisoning generally occurs in autumn and winter, because the low temperature, low air pressure and poor indoor air circulation in autumn and winter are the most likely to lead to gas poisoning accidents. Of course, there will be gas poisoning accidents in summer, more often when we use air conditioning.
student activities: group inquiry learning:
first, the principle of gas poisoning? Write on the blackboard
1. Discuss in groups. Students in each group discuss according to the principle of gas poisoning they know from news, newspapers and other channels.
2. The teacher asks questions from each group.
Teacher's comment:
1. Gas poisoning usually refers to carbon monoxide poisoning. If the content of carbon monoxide in the air reaches 1.14%-1.16%, people can be poisoned.
2. Carbon monoxide is colorless and odorless. It often invades people's respiratory tract unconsciously under unexpected circumstances, especially during sleep, enters the blood through gas exchange in alveoli, and spreads all over the body, causing poisoning.
3. The binding capacity of hemoglobin with carbon monoxide in blood is more than 211 times stronger than that with oxygen, and the separation speed of hemoglobin and oxygen is very slow. Therefore, once people inhale carbon monoxide, oxygen loses the chance to combine with hemoglobin, so that tissues and cells can't get enough oxygen from the blood, which makes the human body lack oxygen and makes it difficult to breathe.
4. The time of symptoms of carbon monoxide poisoning and the severity of poisoning are closely related to the indoor concentration of carbon monoxide and the age of the poisoned person. Young people are more sensitive than the elderly, and pregnant women, obese people and people with chronic heart and lung diseases are also prone to poisoning.
The doctor reminded that carbon monoxide poisoning is the most harmful to the brain nervous system and palpitation, leading to blood supply obstruction and hypoxia, with a high disability rate, which is easy to cause delayed encephalopathy, and the treatment is recovered.
