How to provide first aid when gas suffers

Recently, the gas suffocation in Thanh Hoa lime kiln caused 8 deaths and many people were puzzled and afraid. In order to avoid unfortunate accidents, you should also equip yourself with basic knowledge to deal with situations caused by gas suffers.

Doctor Hoang Dai Thang, Head of the intensive anti-toxic department (Dong Nai General Hospital) shared, to be able to cope with the situation of gas poisoning, it is necessary to identify types of gas, gas and smoke causing suffocation. . Smoke can easily be detected in situations of fire due to electric shock, firewood. However, situations that cause suffocation by gas, toxic gases are often difficult to see as being suffocated by toxic gases emitted from engines of cars, motorcycles, generators, gas, ammonia, hot steam .

Symptoms of asphyxiation of CO

The symptoms of CO suffocation are: lacrimation, conjunctivitis, coughing, sputum expectoration with coal, difficulty breathing, disorientation, loss of perception, burns, burning skin, hair, hair . If mild, often manifest shortness of breath, nausea, headache; On average, the victim feels severe headache, dizziness, neurological disorders, nausea, fainting; severe fainting, lethargy, seizures, arrhythmias, vascular collapse and death .

Symptoms of asphyxiation CO ₂

Associate Prof. Dr. Tran Hong Con (Faculty of Chemistry, University of Natural Sciences, Hanoi National University) said death cases due to CO ₂ inhalation are very gradual, like a deep, unforeseen sleep.

The odorless, tasteless, odorless CO ₂ gas therefore, the victim did not have a self-defense reaction, the body did not "warn" dangerously to promptly escape the room. When shocked by the lack of oxygen, suffocating body, difficulty breathing, they immediately fell into a state of coma and death from asphyxia.

The scene of the gas leak in the lime kiln caused 8 deaths.

According to experts, it is common to have severe asphyxiation, such as chest pain, palpitations, disorientation, seizures, coma, arrhythmia, hypotension, myocardial anemia, burns. skin, urination, incontinence.

Outsiders can see the victim faint, shortness of breath, pink foam breathing, swollen limbs, purple in the lips and fingertips, toes, dark urine, red and less or no movements often.

The injury when gas suffocation, smoke

When CO enters the body, it pushes oxygen out of the blood, preventing oxygen from reaching cells and cells that die. In addition, CO gas acts directly on the heart muscle to reduce the contraction of the heart, the effect on the brain reduces neurotransmitters, thereby reducing blood pressure.Severe, life-saved victims often leave neurological sequelae, such as: parkinson's disease, cognitive disorders and personality disorders .

First aid and treatment when victims suffocate

When you see a person suffocating gas, they need to open all the doors to allow air to enter and immediately bring the victim out of the area with toxic gas, quickly bring to the hospital for emergency , limit the sequelae.

People who come to the emergency room also need to quickly call for additional support to prevent toxic gas. The process of hospitalization if the victim is breathing weak or unconscious, needs to breathe breathlessly.

In case the person himself is in a closed room that uses a generator or utensil to produce CO2, when the body feels difficult to breathe, is slightly shocked, quickly wake up and open the room , if left for long The body fades away. After opening the door, turn off the equipment immediately or step outside the room to avoid fatigue due to lack of gas.

In order not to suffocate, experts recommend that people do not use charcoal or wood to burn and heat in a closed room without air. Do not run engines using gasoline and oil in closed areas . Do not use gas burners without ventilation in closed rooms or in bedrooms.

Everyone should avoid gathering crowded public places like parking basements . In addition, buildings must design ventilation systems, ensuring oxygen flow.

Preventing poisoning of gases, vapors, toxic fumes

1. Safety in electricity use, careful firewood, gas stove is essential.
2. Do not leave a car or motorbike running at home, in the garage even when opening the door; do not place generators in the house; do not burn coal or wood in the house when closing the door; Do not use gas burning equipment in enclosed rooms or bedrooms.
