  What is carbon monoxide poisoning?

  In a confined space, if you feel dizziness, chest tightness, or even weakness in your limbs when using coal, natural gas or air conditioning in the car, you must not take it lightly - this may be carbon monoxide poisoning!

  When carbon monoxide is mildly poisoned, the consciousness is still clear, and there are only symptoms such as dizziness and nausea.

At this time, if you continue to stay in the carbon monoxide environment, symptoms of coma, collapse, and flushing will appear. At this time, you have moderate poisoning.

If you continue to inhale carbon monoxide and enter into severe poisoning, the patient will be in a deep coma, his reflexes will disappear, he will become incontinent, his skin will turn from cherry red to gray or purple, his blood pressure will drop, and his breathing will be rapid, and he will die soon.

  How to save yourself and help yourself?

  When symptoms such as dizziness and nausea appear, immediately open the window for ventilation, and leave the carbon monoxide environment. If you have symptoms of fatigue, carbon monoxide is lighter than air, so you should crawl away.

  In an emergency, keep the following principles in mind:

  1. Quickly get out of the poisoning environment and move to a place with fresh air and good ventilation.

  2. Untie the collar buttons and belts of the poisoned person, keep the airway unobstructed, and keep lying on the side to prevent vomit suffocation.

At the same time, keep warm to prevent complications.

  3. Patients should keep quiet and rest, avoid activities that increase the consumption of oxygen, and allow patients to inhale oxygen as soon as possible.

  4. Dial 120 as soon as possible and send to the hospital for rescue.

  It is understood that patients with mild poisoning will get better after resting for 2-3 hours in a place with fresh air, but moderate and severe patients should be sent to a hospital with a hyperbaric oxygen chamber for treatment as soon as possible after on-site first aid to prevent serious complications and sequelae. occur.

  How to prevent carbon monoxide poisoning?

  Since carbon monoxide is colorless and odorless, most of the discomfort reactions have already occurred when it is discovered, so it is extremely important to do preventive work in advance.

  When using heating equipment such as coal stoves and charcoal fires indoors, the coal should be burnt out, and the cover should not be stuffed. During use, the doors and windows should be opened frequently for ventilation to keep the indoor air fresh.

  Choose stoves purchased from regular channels, and the chimney interface should be firmly connected and kept smooth.

  Check the vents and flues frequently to ensure they are working properly.

  Coal stoves, charcoal fires and other heating equipment should not be placed directly in the bedroom; if conditions permit, it is best to move the stove outside the house before going to bed at night.

  Under meteorological conditions such as rain, snow and hail with low pressure and high relative humidity, try not to use heating equipment such as coal stoves and charcoal fires; when eating hot pot at home, it is best not to use coal or charcoal hot pot. Ventilate the hall or keep doors and windows open for ventilation.

  In addition, units or homes that use coal stoves, it is best to install carbon monoxide detectors, and regularly check and maintain to ensure the normal operation of the detectors.

  When using a gas water heater, a safe and reliable equipment manufacturer should be selected, and professionals from the gas group should be invited to install it and inspect it regularly; pay attention to regularly check whether the exhaust pipe is unobstructed.
