This is the way coal gas - CO killed male singer Jonghyun (SHINee)

No one could doubt, this odorless, colorless gas could defeat people so quickly!

The question is, is it possible to kill people?

Sorry, the answer is yes . Be aware that charcoal burning in the absence of air creates an extremely toxic gas called carbon monoxide (CO) .

Coal gas emits a lot of CO - a silent killer.

Victims of inhalation of this gas are seriously fatal, leaving a neurological-mental sequela.

How does carbon monoxide kill people?

Needless to say, carbon monoxide (CO) is a colorless, odorless gas, emitted from fuels such as charcoal, propane, methane, or petroleum burning halfway (incomplete combustion).

When the body inhales this gas, it enters the lungs and enters the bloodstream, where CO combines with hemoglobin (red blood cells) in the blood to form carboxy hemoglobin (HbCO).

This substance prevents the release of oxygen in the cell, reducing the ability of the blood to transport oxygen, leading to hypoxia.

When the red blood cells are completely out of oxygen, the body also depletes oxygen. In addition, CO gas can also combine with myoglobin (muscle pigment) to damage cells and generate acid metabolism.

Because it is a colorless, odorless, non-irritating gas, it is difficult for the victim to sense the presence of CO in the air.

Only when the victim begins to feel "abnormal" is the limb unable to move, lethargic and leads to death. The reason is that CO gradually creeps into the body causing hypoxia in the blood, in all organs.

The more oxygen a body needs, the more brain and heart . the more dangerous it is.

Symptoms of CO poisoning

Symptoms of CO poisoning usually start with a feeling of headache, nausea, dizziness, difficulty breathing and slowly enter a coma.

At heavier levels, the victim will feel chest tightness, blurred vision, shortness of breath, rapid pulse . the lungs seem to be blocked, no longer functioning.

At this time, the victim may have seizures, unconsciousness, permanent brain damage, cardiac arrest and death.

What to do when detecting victims of CO asphyxiation?

Suspecting that people who have been poisoned by carbon monoxide will immediately need to take the sick person out of the area, or open all the doors so that the air will spill into the house - in any way to stop the patient from accessing CO.

If the patient is mildly mild, he will recover quickly and recover. However, in more severe cases, CPR should be carried out quickly and the patient should be admitted to the emergency room.

Emergency victims should also call for additional support, in case they are affected by toxic gases.
