In the hot summer, I believe many poplars like to soak in the water to cool off like little rescuers. Swimming and splashing water can be described as a cool magic weapon to cope with the heat, but in the water, danger will quietly approach at any time. Especially in the wild river pond, there is no one to look after and supervise, the situation in the water is ever-changing and unpredictable, and your physical condition is also uncertain. You may be one step away from drowning.

First of all, small rescue must first correct some misunderstandings about "drowning"

1. Do you shout loudly after drowning? no

Fact: Drowning always happens quietly. Drowning people often want to shout but can't make a sound, and some are like "lying" or "standing" in the water.

Can you swim without drowning? no

Fact: Underwater is very dangerous, especially in wild waters such as reservoirs, ponds and rivers. Leg cramps, physical fatigue, fasting, etc. It will also lead to the inability to swim normally and drown.

3. Is it safe to have a swimming ring? no

Fact: No equipment can completely guarantee the safety in water. When the swimming ring is suddenly turned over by the push of water, or when the swimming ring suddenly leaks air, it may also cause drowning.

Ten manifestations of "drowning"

Have you ever been deceived by film and television dramas before and fallen into the "misunderstanding" of drowning? So what is the real situation of drowning? Next, let's take a look at the top ten performances of drowning with small rescuers.

1. Head in water, mouth in water.

Close your eyes.

distraction

Lean back and breathe with your mouth wide open

Cover your hair

Hyperventilation

7. Stiff legs

8. Climb a ladder

9. Just swim but don't move.

10. Turn it over and face down

? Of course, due to the difference of current situation and personal situation, the performance of drowning is not the same. If you find yourself or others have the above performance, you need to be alert to whether drowning has occurred. When drowning happens, time is life, so first aid should be given to the drowning person at the first time.

The main manifestations of drowning are suffocation, respiratory dysfunction caused by cold, and even cardiac arrest, which leads to different degrees of damage to the heart, lungs and brain. The time and degree of hypoxia directly affect the success rate of cardiopulmonary resuscitation and the effect of cerebral resuscitation. From the clinical experience, the survival rate is as high as 50% within 5 minutes after timely and effective treatment, the mortality rate rises linearly after 6 minutes, and the probability of brain death reaches 100% after10 minutes.

Swimming exercises to cool off the heat, but safety always comes first. Everyone must consider his own situation when swimming or paddling. If you feel unwell, go ashore to rest or ask people around you for help. Don't be brave.

If someone is drowning, don't blindly go into the water to rescue him. In order to rescue the drowning person while ensuring his own safety and correctly judging him, it is best to call the emergency number first and call for help more often.
