People who are drowning don t necessarily cry out for help, what are the reasons?

The environment we live in will undergo various changes all the time, with the continuous development of social economy and the continuous progress of science and technology, people's education level is getting higher and higher, and people's awareness of various risks is getting higher and higher. But it is inevitable that all kinds of accidents will happen around us, including accidental drowning. So in the process of drowning, we will find some problems, that is, the drowning person does not necessarily shout for help, what is the reason for this?

For such a problem, his drowning has caused breathing difficulties to a certain extent, and a lot of water enters the digestive system from his mouth, so he is suffocated to a certain extent, and feels very bloated, so the combination of the two will lead to difficulty in pronunciation, and it takes a lot of air to make a sound, and it is difficult for people to do such a thing in the rain, so the drowning person may not necessarily make a loud shout.

I have to say that there are still all kinds of drowning incidents in our real life. The occurrence of drowning is related to the change of seasons to a certain extent, and the probability of such a thing happening in summer is very high, so for this situation, we should detect it as soon as possible, and control can suppress the occurrence of such a thing to a certain extent. But I have to say that we need to pay more attention to one point, that is, to strengthen the teaching of some minors' swimming skills, so that such things can be avoided to a certain extent.

Therefore, we should realize how important education is for our safety, we not only need to learn some knowledge in textbooks, we should also learn some survival skills, which is a very important thing for us, so when we have time, it is still very necessary to learn some swimming or safety knowledge.

Because drowning people don't have enough oxygen in the water, if they speak loudly, they will choke on the water around them, and they may be in danger of suffocation.

First, the mouth and nose are not necessarily above the surface of the water, they may be in the water, and they cannot be heard even if they shout. Second, even above the surface of the water, the mouth and nose are full of water, and it is too late to spit out the water in your mouth and then inhale, because it may soon sink again.

Because they are drowning, they simply don't have time to shout for help, and they don't have the physical strength to shout for help, plus they have been choking on water in their mouths, so they simply have no conditions to shout for help, which is why they won't shout for help.

Because people don't think about that when they panic, they usually think of self-help first, thinking that they should be able to solve it.

Because you can't show your head after drowning, there is no way to shout for help, and learning to swim is especially important.

Because this will consume physical strength, and it will also cause people to be very emotionally stressed, and it is likely to cause the drowning person to sink quickly, and this behavior is also very dangerous.

Now after the arrival of summer, all kinds of minors or adults who swim and bathe in the river will have, but every year we will see various places report that the river water in which place accidentally leaks and causes death will appear repeatedly, in fact, although we have heard of this situation, but the immersive feeling is still relatively few, after all, such as drowning in the water and other situations can not be experienced, can only be warned. In general, drowning is very serious, but many people have not experienced it, but they also want to understand the whole process of drowning.

In fact, the characteristics of drowning are basically the same, if a person can't swim, in the water will be very painful struggle, of course, at the beginning of the fall into the water may have a very strong desire to survive and struggle a time to fall into the water will be very quiet, hands will keep stretching up, arms will be opened, and even the head has a very large upward process, mainly to let the head contact with the air, breathe more air, and then there will be a lot of splashes around the drowning water, which is the same characteristic, But even if you struggle like this, it's very difficult to move because you can't swim.

A person who falls into the water may call for help first, but when he or she is drowning, what is urgently needed is air. Unable to call for help, the drowning person struggles to get their nose and mouth out of the water, and will open their arms in an attempt to get themselves out of the water.

Can't shout. I used to fall into the water and my mouth couldn't get out of the water. It's just that the hands and feet are hard enough to tread the water, and if you are lucky enough to go in the right direction, you will instinctively spit out the water in your mouth first, and then inhale, and generally sink again when you inhale.

Many times the mouth and nose are below the surface of the water.

Drowning people usually grab everything around them, and secondly, they will also shout for help, but basically they will drink a lot of water in one mouth, so they can't make a sound at all.

It depends on the situation, some people will call loudly, but some people have no way to call out, so you must always pay attention to the people around you.

No, because some of the water has already entered the nasal cavity, and the drowning person cannot make a loud sound.

Cardiopulmonary resuscitation. For patients with cardiorespiratory arrest, on-site cardiopulmonary resuscitation should be performed immediately, including opening the airway, removing foreign bodies such as sediment and aquatic plants in the mouth and nose, mouth-to-mouth rescue respiration, and chest compressions. Be aware of the heartbeat, and breathing may stop again when breathing resumes.

At the same time as the rescue at the scene, an evacuation should be organized.

Drowning patients develop severe hypoxia after a period of time, first causing loss of cerebral cortical function, coma, respiratory arrest if oxygen is not available, and cardiac arrest if hypoxia is not corrected. Therefore, the absence of breath in the heartbeat is a stage of severe drowning, which indicates that the patient is on the verge of death.

Patients who are fished out after 3 or 4 minutes of drowning often need artificial respiration, and most of those who are fished out after 5 minutes of drowning have already suffered cardiac arrest and need immediate cardiopulmonary resuscitation.

Generally, drowning occurs in swimming pools, reservoirs, puddles, ponds, rivers, streams, seashores, etc. Every summer, there are drowning accidents in swimming. Among the drowning people, there are some people who can't swim, and some people who can swim and have good water skills.

Rescuing a drowning person is a very dangerous action, the theory is very simple but the actual operation is very complicated, to consider the water flow, their own physical strength, the distance of rescue, undercurrents and other factors, every year there are unarmed rescue accidents that lead to the drowning person and lifeguards at the same time! The instinct of the drowning person is to grab everything that can be grasped, and the experienced lifeguard will not approach the drowning person very quickly, and it is easy to be held by the drowning person and unable to break away if he is too anxious to approach, and the tragedy will repeat itself again!

So, if someone is drowning, how do you rescue them?

2.After finding a drowning person, you can make full use of on-site equipment, such as ropes, rods, wooden boards, lifebuoys, etc. You can also use clothes together as ropes.

3.When you need to go into the water to save someone who is drowning, be sure to tell him out loud, don't panic, someone is saving you.

4.When going into the water to rescue people, do not approach from the front to prevent being grabbed and hugged by the drowning person. If you are caught, you should let go and sink yourself, and the drowning person will let go.

The rescuer should go around the back of the drowning person or dive underwater, go around the chest from under his left armpit, and then hold his right hand and drag him or her to the shore in a supine position, or pull his armpit behind his back to drag him ashore.

5.If the rescuer is not familiar with the water or does not understand the water conditions at the scene, he should not enter the water lightly and should call for help or call the police. Minors should not go into the water to save people.

If you find that someone is drowning, first of all, shout for help first, call more people to help, if the drowning person is not far from the shore, you can find a rope or bamboo pole nearby to pull the person ashore, or connect the clothes together as a rope, when you need to go into the water to rescue the drowning person, you must tell him loudly, don't panic, someone is saving you, it is best to go around behind the drowning person when rescuing, do not rescue head-on, that may hold the drowning person to death, hold up the drowning person with his hand when rescuing, try to let him call for help in the air, Then push it towards the shore.

1. Use a long bamboo pole to pull the drowning person ashore.

2 call, ask for help.

In the human lungs, there is something called the alveoli, which is filled with capillaries (possibly capillaries).

The function of the alveoli is to capture oxygen from the air and catch the load with red blood cells, while releasing carbon dioxide loaded by red blood cells. (Of course, all this is premised on the beating of the heart).

When a person is drowning, the alveoli are unable to get oxygen from the water (just like a fish can no longer move oxygen in the air).

We will die from lack of oxygen to the brain.

People die by drowning because there is a problem in the gas exchange between the human body and the outside world, because the water blocks the airways.

The breath of the person. There must be a difference in air pressure between the lung cavity and the outside world. When a person's lungs are balanced with the outside world after drowning, it is fatal to lose breath.

When a person is drowning, he instinctively tells himself not to breathe, but when he drinks water again, when he does not breathe for a minute or two, he will fall unconscious, leading to death.

It is the lung ventilation link.

That's all I need to say.

Once someone is drowned in the water or accidentally falls into the water, how to rescue them? Here's how to do it:

1. If the drowning person is conscious and fluttering on the surface of the water, he can throw wooden planks, bamboo poles and other rescue equipment into the water to help him swim ashore or swim onto the boat. If the person who falls into the water is on the shore or in the water nearby, he can be pulled directly by hand or thrown with clothes.

2. If the drowning person has gone to the bottom of the water or is terrified, the rescuer should quickly dive into the water for first aid, but should prevent the drowning person from being dragged to the bottom.

3. After the person who has fallen into the water comes ashore, whether he is awake or not, he should remove the mud and weeds from his mouth and nose, and at the same time, his face should be tilted to the side to remove the water from the respiratory tract and avoid the tongue blocking the respiratory tract. If breathing is found to be weak or stopped, rescue breaths should be given immediately.

4. If the drowning person is breathing normally, he should lie on his stomach, so that the abdomen is raised and the head is drooped to facilitate drainage.

5. If the weather is cold, you should also pay attention to the warmth of the drowning person to reduce the occurrence of complications.

6. Find it on the Internet.

Check the mouth for foreign bodies before giving rescue respiration or cardiac resuscitation.

Press your hands on your chest and give rescue breaths together.

With your head down and your waist up, press on your back to clear the water.

Put the drowning person on the knee and press on the back, artificial respiration, heartbeat compressions.
