Carbon monoxide is a colorless, odorless and tasteless flammable gas. It is often produced due to insufficient fuel combustion in daily life. Inhalation has toxic effects on tissues and cells throughout the human body, especially the cerebral cortex. However, if the treatment is timely, the patient can generally recover completely within a few days with no sequelae. Therefore, mastering effective self-rescue and rescue knowledge can minimize the damage of carbon monoxide poisoning.

The main places of carbon monoxide poisoning include living rooms with heating equipment such as coal stoves and charcoal fires, kitchens with gas, gas and gas stoves, and bathrooms or shower rooms with gas water heaters. In addition, closed air-conditioned cars and garages using small oil and steam generators are also high-risk places for carbon monoxide poisoning.

How to prevent carbon monoxide poisoning?

1. The water heater or gas at home should not be placed in the room where the family is active, and the gas water heater should not be installed in a closed bathroom or in a poorly ventilated place.

2. When purchasing gas and gas water heaters, you need to choose water heaters with qualified quality produced by regular manufacturers; you must ask professionals to install them and use them after passing the test. Do not change the gas and gas pipeline facilities without permission.

3. When using gas or gas water heaters, it is necessary to maintain a good ventilation state, and the bathing time should not be too long. After use, check whether the water heater is completely turned off.

4. Regularly repair the pressure reducing valve and leather pipe of gas and gas water heaters, and replace them in time if they are found to be damaged, rusted, or leaked.

5. When using gas and gas water heaters at home, it is best to install carbon monoxide detectors and regularly check and maintain them to ensure the normal operation of the detectors.

6. When using gas in daily life, keep the room well ventilated at all times, especially in winter and rainy days; smell the smell of gas before using gas appliances to determine whether there is air leakage; when the automatic ignition gas appliances are not ignited continuously, they should be Wait for a while for the outgoing gas to disperse before igniting.

The symptoms of carbon monoxide poisoning are manifested in the following aspects:

1, mild carbon monoxide poisoning. Patients may experience headache, dizziness, blurred vision, nausea, vomiting, tinnitus, tachycardia, malaise, and transient fainting. The content of carboxyhemoglobin in blood is 10% to 20%.

2, moderate carbon monoxide poisoning. In addition to the above symptoms, nails, lips, skin and mucous membranes appeared cherry red, blood pressure first increased and then decreased, sweating, arrhythmia, irritability, thinking, but unable to act. Symptoms continue to worsen, and coma and drowsiness may occur. Blood carboxyhemoglobin is about 30% to 40%. After timely rescue, can wake up quickly, generally without complications and sequelae.

3. Severe carbon monoxide poisoning. The patient quickly went into a coma. In the early stage, the muscle tone of the extremities increased, or there were paroxysmal tonic spasms; in the late stage, the muscle tone was significantly reduced, and the patient was pale or bruised. The pupils were dilated, blood pressure dropped, and eventually he died from respiratory paralysis. The rescued survivors may have serious complications and sequelae.

If others are found to be poisoned by carbon monoxide, the following principles should be followed:

1. The rescuer should enter the scene on a prostrate;

2. Open the doors and windows for ventilation, quickly transfer the poisoned person to a ventilated and warm place to lie down, and untie the collar and belt to facilitate their breathing;

3. For comatose patients, turn their head to one side to prevent vomit from being inhaled into the lungs and cause suffocation;

4. If the heartbeat and breathing are weak or have stopped, perform cardiopulmonary resuscitation immediately;

5. Call an ambulance at the same time and send the poisoned person to a hospital with a hyperbaric oxygen chamber for rescue.
