Kneel to save people's jokes

The video of a nurse kneeling to save people attracted countless netizens to watch and sent us positive energy. A man fell to the side of the road because of excessive exercise, and a nurse, Wang, knelt on the ground for more than 20 minutes to give first aid, regardless of his leg injury, and finally got the man out of danger and regained consciousness. If the nurse didn't happen to pass by, then the onlookers could only wait for 120, and missed the prime time of rescue, which is enough to show that first aid knowledge should be popularized. Summarize the following aspects to let everyone know more about first aid.

① Definition of first aid First aid refers to the correct treatment of the wounded and sick by using all available materials at that time before the arrival of 120 when any disease or accident suddenly occurs. Research shows that first aid can prevent the disease from getting worse and help the disease recover.

② In the important first aid of cardiopulmonary resuscitation, cardiopulmonary resuscitation should be regarded as a skill that all people should master. If the patient has cardiac arrest, judge whether the strong artery beats for 5 seconds, and if not, immediately perform cardiopulmonary resuscitation. The compression point is located in the middle of the connecting line between the two nipples. The compression depth of adults is 5-6cm, and the compression frequency is 100 times per minute. Do artificial respiration twice every 30 times. Repeat it five times, and then judge whether the carotid artery beats again. If not, continue to carry out cardiopulmonary resuscitation until the professionals arrive. Cardiac arrest, often organs can only withstand ischemia for 3 minutes. If the heartbeat is restored within 3 minutes, the cure rate will be greatly improved. If it is not treated in time, even if it is finally rescued, it will cause irreversible damage to other parts.

(3) Common types that need first aid In fact, there are many common things we can do in life. For example, if a foreign body is stuck in the trachea, you should use Heimlich first aid immediately, especially if you have young children at home, parents must master it. Another example is heatstroke. You can immediately drag the patient to the shade, lie flat, unbutton his clothes and dissipate heat as soon as possible. Call 120 if the situation is serious.
