How long does it take for a person who can t swim to be rescued once they fall into the water

If a drowning person can put his head out of the water and can breathe, it is generally not life-threatening (referring to the period of drowning, not being in the water for a long time, "such as more than a few days"), if the drowning person is below the water surface, can not breathe air,If it is more than 4 minutes, it is life-threatening.

If someone is found drowning, the best rescue time is 4 minutes。"When there is no oxygen in the water, the oxygen in the body is enough for you for 4 minutes, when the water is deprived of oxygen for 4 minutes, the cells of the brain will begin to die, the shorter the rescue time, the better, so that the chance of the drowning person leaving sequelae is very small. ”

When the drowning person is rescued ashore, do not waste time to do water control actions, because the main cause of the death of swimmers is suffocation, and this suffocation is caused by water in the trachea and lungs, so when the drowning person loses consciousness, no breathing, no pulse, or sigh-like breathing, he should be given cardiopulmonary resuscitation as soon as possible, be sure to ensure the oxygen supply to the brain, and call 120 emergency ** for help.

Drowning Emergency Treatment:

The root cause of drowning is hypoxia. "The water control pours out the water in the stomach, because the drowning person will swallow water repeatedly before suffocation, resulting in the stomach being filled with water, but the fatal root cause is not that the person drinks too much water, but the lack of oxygen caused by suffocation.

Even if water enters the lungs and causes a lack of oxygen, ordinary methods of water control, such as handstands, punching the abdomen, and slapping the back, are ineffective. The water in the lungs can only be carried away by the blood flow created by chest compressions. In addition, many early drowning people do not have a lot of water in their lungs due to asphyxia caused by reflex laryngeal spasm.

After fishing people up, you can't control the water first, so as not to delay the rescue time, but you should first judge whether the drowning person is unconscious and breathing, and call for help or call 120 as soon as possible.

If the drowning victim is conscious and does not have dyspnea, the airway should be kept open, and the water should be dried as much as possible, while keeping him warm and waiting for the ambulance to arrive. If the drowning person is unconscious but still has breathing and a pulse, the mouth and nose should be cleared first, the airway should be cleared to the lateral decubitus position, and the drowning person should be closely observed until an ambulance arrives.

The above content reference: People's Daily Online - Drowning incidents are frequent, and there are scientific steps for self-rescue and saving people.

The sooner the better, there may be hope for the correct and timely rescue within 6 minutes, and the chance of survival beyond 6 minutes is very small.

2 of them are saved together, there are only 2 parents in this life, and neither of the 2 parents can not be saved.

If you don't know how to swim and see someone overboard, the best thing to do is to call for help, that is, to shout loudly to the surroundings so that people around you know that someone has fallen into the water, and also explain that you can't swim. This not only ensures your own personal safety, but also gives the person who has fallen into the water a chance to be rescued, which is the safest way. If you can't swim, if you rush into the water, you can't save others, and at the same time add chaos to the rescuers, so that the real rescuers can't tell who to save first, so people who can't swim, when they see someone falling into the water, the first choice must be to call for help!

If the person who fell into the water is not far from the shore and happens to have a tool such as a rope or bamboo pole to rescue, then you can choose to rescue the other party by yourself at this time; If the amount of water at the point of falling into the water is not large, and the water is not deep, you know more about the depth of the water in this area, you can choose to go directly into the water to rescue, but these situations are generally rare, most of the cases are that the rescuer and the person who fell into the water are not clear about the depth of the water in the water, and there is no corresponding rescue tool, so choose to shout for help, or suitable for every rescuer who can't swim.

Whether it is rescuing people who have fallen into the water, or rescuing other groups of people, in fact, we must do what we can, to measure whether we have the ability to save people, if we do not have the ability to save people, it is best to choose other rescue measures, after all, saving people also requires skills and strength, if you don't have that ability, it is easy to backfire, so before doing anything, you must think about the consequences, don't be impulsive, after all, "impulse is the devil" is suitable for everyone. The starting point is good, it may not be able to do good things, sometimes it is often to add chaos, and vice versa is also true, it seems that there is no direct rescue of the other party, but often inadvertent small actions, but instead play a greater role, so do not underestimate the power of "calling for help".

In short, for the sake of their own safety, but also for the safety of others, people who can't swim can choose to call for help as soon as they see someone falling into the water is the most rational arrangement.

I would immediately shout for help, call the police** quickly, and try to find tools around to help save people, hoping to help people fall into the water as quickly as possible.

Depending on the situation, someone called someone, no one called the police, looking for tools to remedy.

I would immediately ask for help from the people around me. Go for those who are good at water. So that there will be no tragedy.

Summary. As long as you are calm, you will not drown, and under normal circumstances, the air in the human chest cavity is enough to float your body in the water. But if it's like crazy, it's a matter of minutes.

When you fall into the water, your heart will stop beating due to the lack of oxygen. You are very clear at the moment, but you have lost control of your body, but the consciousness of your head is clear. But it won't be long.

Because the longer it takes, the more blurred your sensations will be, as the heart stops beating and the oxygen in the blood decreases, causing brain cells to start dying. Under normal circumstances, about 10 minutes, the brain will die without oxygen, of course, the specific time is also a little different from the human physique. If your brain cells die on a large scale, even if your heart beats again, you can't come back, and even if you do, it's a vegetative state, or something that can only be maintained by a machine.

The human body is a complete machine. The heart is like a fuel tank, the brain is the engine, and when the engine is broken, the fuel tank is useless.

Once a person with average water or non-swimmers falls into the water, how long it takes to be rescued may not be life-threatening.

Different people are different.

You only have to be calm, you won't drown, under normal circumstances, the air in a person's chest is enough to float your body in the water. But if it's like crazy, it's a matter of minutes. When you fall into the water, your heart will stop beating due to the lack of oxygen.

You are very clear at the moment, but you have lost control of your body, but the consciousness of your head is clear. But it won't be long. Because the longer it takes, the more blurred your sensations will be, as the heart stops beating and the oxygen in the blood decreases, causing brain cells to start dying.

Under normal circumstances, about 10 points of envy, the brain will die in the absence of oxygen, of course, the specific time is also a little different from the human physique. If your brain cells die on a large scale, even if your heart beats again, you can't come back, and even if you do, it's a vegetative state, or something that can only be maintained by a machine. The human body is a complete machine.

The heart is like a fuel tank, the brain is the engine, and when the engine is broken, the fuel tank is useless.

When encountering such a situation, it is extremely important to take a breath before sinking, and it is also the key to survival. When sinking, you should keep your composure, close your lips, clench your teeth, hold your breath, and if you want to struggle desperately in the water, you should raise your head, tilt your body, and maintain this posture, and you can slowly rise to the surface. Once on the surface, don't lift your hands out of the water, but paddle under the surface so that your head is above the surface so you can breathe air.

If possible, remove shoes and heavy clothing, look for floaters and hold on firmly. At this time, you should call for help to pedestrians on the shore and paddle regularly on your own, swimming slowly towards the shore.

Second, will the roof of the downstairs be wet if the bathroom leaks?

This slight water seepage can cause changes in the roof of the downstairs bathroom to yellow, and over time, mold can develop in the seepage area. With the naked eye, it is black. This can make the air quality in the restroom very poor under such conditions.

In addition, if there is a noisy circuit in the bathroom, there may be a short circuit in the electricity.

The root cause of slight water seepage in the bathroom is that there is a partial damage to the waterproofing of our bathroom, but the damage is not particularly serious. In the process of using water, there is water through this broken area, which slowly penetrates into the roof below. After the bathroom does not use water, it slowly dries out again.

That's what it shows.
