BG digital currency website cannot be opened
after September 4 last year, all domestic digital currency exchanges were closed or moved abroad. Many website servers and trading platform clients are fully accessible, which also leads to a part of the air money and MLM money is still in a very arrogant process
since March, the domestic regulatory level has strengthened the shielding of foreign digital currency trading platform websites, resulting in many digital currency trading websites and platforms not landing.
It's deceiving. It's living by deceiving shareholders' money
let the salesman add wechat friends in the name of recommending stocks, and then pull the friends into the "Bull Stock Exchange Group" and other stock exchange groups. Let the swindlers play the role of "experts" in the group to teach and ince customers to invest in futures index
several salesmen played the role of "Tuo", preaching and showing off how to make money through futures index in the group. Once a customer has an investment intention, the suspect will be lured to a false platform to buy a false stock, and then secretly back-end operation ups and downs, the customer investment looted
extended materials:
at present, the ways of recommending stocks to earn money are mainly divided into the following types
the first type: open a live studio and sell courses P>
has a "exclusive private exchange circle" in the stock selection official account. It is known that the investors can interact with teachers in a zero distance, and solve difficult problems, help you to prompt risks, diagnose stocks on hand and dig out potential stocks. p>
the second type: cooperation sharing
this method is more confusing. The stock sponsor said that it would charge a certain percentage of the profit as reward, but the stock sponsor would only share your profit, not help share the loss
it is necessary to understand the heart and the importance of respiration and blood circulation to human function. The heart is divided into left and right atriums and left and right ventricles. The right atrium inhales the blood containing carbon dioxide from the superior and inferior vena cava, which is transported from the whole body to the alveoli through the right ventricle. The oxygenated blood is then transported to the left atrium through the pulmonary vein, and then to the left ventricle through the pulmonary artery, which is transported to the whole body to maintain the vital function of cells, organs and tissues, Among them, heart and brain cells need more oxygen
principle and importance of CPR
principle of CPR:
the air contains 80% nitrogen and 20% oxygen, including a small amount of other gases. However, the composition of the air exhaled by human respiration is still about 80% nitrogen, 16% oxygen and 4% carbon dioxide, This analysis allows us to understand that the amount of oxygen exhaled through normal breathing is still enough to meet our normal requirements
artificial respiration is used to blow air into the lung cavity, and external massage is used to promote the exchange of oxygen from the lung to the brain and the whole body, so as to maintain the survival of brain cells and organs
the importance of CPR:
when the human body stops breathing and heartbeat, the heart, brain and organs will graally become necrotic e to the lack of oxygen supply. Clinically, we can find that the skin color of the patient's lips, nails and face graally tends to dark purple from the original normal color, and the pupil of the eye is graally expanding, Of course, the ups and downs of the chest and the beating of the carotid artery can more definitely tell us the message of life. The oxygen in the lung and blood can be maintained within four minutes. Therefore, if CPR is done within four minutes, the brain cells will be completely recovered. Between four to six minutes, the brain cells may be damaged depending on the situation. If CPR is done within six minutes, there will be different degrees of damage, Delay to more than 10 minutes will certainly cause necrosis of brain cells e to hypoxia
the application time and steps of CPR
the application time of CPR:
cardiopulmonary resuscitation can be used to prevent brain cells and organs from necrosis in cases of drowning, heart disease, hypertension, traffic accident, electric shock, drug poisoning, gas poisoning, foreign body blockage of respiratory tract and cardiac arrest before medical treatment< Cardiopulmonary resuscitation (CPR)
1. CPR (1) beating in the precordial area after cardiac arrest in 1 minute and 30 seconds, the cardiac stress is the highest. At this time, boxing in the precordial area proces 5-15w.sr electric energy, which can excite the myocardium and proce electric complex wave, and promote the heart to rebound< Methods the right hand was used to loosen the hollow fist. The side of thenar muscle was toward the chest wall of the patient, and the height was 20-30cm from the chest wall. The anterior region of the heart, that is, the lower part of the sternum, was hammered down vertically. Beat 1-2 times, 1-2 seconds each time, with moderate strength. Observe the change of ECG. If there is no change, immediately change to external chest cardiac compression and artificial respiration
2. Precautions
(1) hammering should not be repeated, and the maximum number of times should not be more than two
(2) do not use too much force when hammering. It is forbidden in children to prevent rib fracture< The operator is on the patient's side, with one hand holding the patient's forehead to press backward, so that the head is tilted back, and the other hand holding the neck to lift the neck upward
2. The chin lifter is located on one side of the patient. One hand is placed on the patient's forehead to press the head backward, and the other hand (except thumb) is placed on the mandible outside the chin to lift the chin. Pay attention not to oppress submandibular soft tissue, so as not to oppress airway
3. The mandible holder is located on the side of the patient's head, and his elbows are placed on the same level of the patient's back. He grabs the mandible angles on both sides of the patient with both hands and pulls them upward to make the chin forward and head backward. At the same time, his thumbs can pull down the lower lip to make the oral cavity unobstructed
1. Patient position: the patient is supine on a hard bed or on the ground, and the head and heart are at the same level to ensure cerebral blood flow. If possible, the lower limbs should be raised to increase the amount of heart blood
2. The operator's position is close to the side of the patient's chest. In order to ensure that the pressure acts vertically on the patient's sternum, the operator should stand on the ground or on the footstool or kneel according to the specific situation of the rescue site
3. The following methods were used to determine the location: the operator used the index finger and middle finger close to the patient's foot to determine the lower edge of the proximal rib, and then moved up along the lower edge of the costal arch to the infrasternal notch. The middle finger was close to the sternal notch (excluding xiphoid process), and the index finger was close to the middle finger. Place the palm root of the other hand (the long axis is consistent with the long axis of the patient's sternum) close to the index finger of the previous hand on the sternum. Then place the front hand on the back of the hand, and the two hands are parallel and overlapped. The fingers can be closed, separated or grasped each other, but they should not touch the chest wall< (1) with the help of the strength of the body and upper arm, the alt operator presses the spine to make the chest sink by 3.5 ~ 5cm, and then immediately relaxes and relieves the pressure, so that the chest can reset itself and the heart can relax, which is repeated rhythmically. The time of pressing and relaxing is about the same. When relaxing, the root of palm should not leave the pressing part to prevent the position from moving, but the relaxation should be sufficient to facilitate blood flow back. The pressing frequency is 80-100 times / min< (3) cardiopulmonary resuscitation proceres:
1. Check the patient's consciousness: no response, call for rescue; If there is any reaction, check the injury and call for help quickly
2. Clear the airway and check the breathing: if there is no breathing, open the airway; Breathing, keeping airway unobstructed and calling for help; If the airway is blocked, remove the foreign body; 3. Check the carotid artery: if there is pulsation, perform artificial respiration; (4) cardiopulmonary resuscitation was effective:
1; 2. There are perception, reaction and groan< (5) conditions for termination of CPR:
1
2
3. The operator is exhausted and can no longer perform CPR
4. After cardiopulmonary resuscitation (CPR) lasts for one hour, the pupil is dilated and fixed, and the ECG activity and respiration do not recover, indicating brain and heart death< (6) precautions:
1. The mouth-to-mouth air volume should not be too large, generally no more than 1200 ml, and the chest should be slightly unlating. Blowing time should not be too long, too long will cause acute gastric distention, bloating and vomiting. Pay attention to observe whether the patient's airway is unobstructed and whether the chest is blown up
2. Extrathoracic cardiac compression can only be performed when the patient's heart stops beating
3. Mouth to mouth blowing and chest compression should be carried out at the same time, and the proportion of blowing and compression should be strictly followed. Too much or too little blowing and compression will affect the success or failure of resuscitation
4. The position of external cardiac compression must be accurate. It is easy to damage other organs if it is not accurate. The intensity of pressing should be appropriate, too big and too fierce is easy to make sternum fracture, causing pneumothorax and hemothorax; The pressure is too light and the chest pressure is too low to promote blood circulation
5. During cardiopulmonary resuscitation, the patient's buttons and trouser belts should be loosened to avoid visceral injury
