What are the hazards of carbon monoxide?

Do you know the hazards of carbon monoxide? Carbon monoxide (CO) is a colorless, odorless gas， a toxic pollutant. It is highly toxic to the blood and the nervous system.

Normally, the oxygen entering the bloodstream through the respiratory system will bind to hemoglobin (hb), forming oxyhemoglobin (o2hb) which is transported to various organs and tissues of the body and involved in normal metabolic activity. For example, if the concentration of carbon monoxide in the air is too high, much of the carbon monoxide will enter the body’s bloodstream.

The degree of harm of carbon monoxide to the body mainly depends on the concentration of carbon monoxide in the air and the length of time that the body absorbs carbon monoxide.

For example, if the concentration of carbon monoxide reaches 30ppm, the level of carboxyhemoglobin (cohb) in human blood reaches about 5%, which can lead to visual and hearing impairment. When the amount of carboxyhemoglobin (cohb) in the blood reaches more than 10%, the body will be severely damaged Such as headache, dizziness, nausea, chest tightness, fatigue, confusion, etc.

Carbon monoxide poisoning can also cause serious damage to the heart.When the cohb reached more than 5%, coronary blood flow increased significantly; when cohb reached 10%, the coronary blood flow increased by 25% and the amount of oxygen uptake by the myocardium decreased, resulting in the decrease of oxidase System activity stopped.

Normal levels of cohb in humans range from about 0.5% to about 10%, and when the cohb content reaches 25% to 30%, it shows signs of poisoning and falls into a coma after a few hours. When the cohb content reaches 70%, people will die instantly. Blood cohb content of 30% to 40%, the blood showed cherry red, the skin. Nails. Mucosa and lips are displayed. At the same time, there are also headache. Nausea. Vomiting. Palpitations and other symptoms, and even fainted. Poisoning convulsions, brain and lung edema, myocardial damage and other symptoms, such as failure to rescue, can easily lead to death.

So, carbon monoxide detector is very important in our daily life, each family needs the carbon monoxide detector to protect their security. When there is carbon monoxide in the air, the detector can detect and alarm in time.
