Emergency treatment for carbon monoxide poisoning: When it is discovered or suspected that someone has been poisoned by carbon monoxide, the following measures should be taken immediately:

(1) Open doors and windows immediately for ventilation - quickly remove the patient Move to a place with fresh air, rest in bed, keep quiet and keep warm.

(2) Ensure that the respiratory tract is unobstructed - the unconscious person should turn his head to one side to prevent vomitus from being inhaled into the respiratory tract and causing suffocation.

(3) Place an ice pack on the head to reduce cerebral edema - For those who are comatose or convulsing, an ice pack can be placed on the head to reduce cerebral edema. Because carbon monoxide inhaled into the lungs through the respiratory tract has a strong binding force with hemoglobin, carbon monoxide quickly combines with hemoglobin to form carboxyhemoglobin, which cannot carry oxygen, causing tissue hypoxia and symptoms in the central nervous system, respiratory system, and circulatory system. and other poisoning symptoms.

(4) Quickly send to a hospital with conditions for hyperbaric oxygen treatment - because hyperbaric oxygen can not only reduce the half-life of carboxyhemoglobin, increase carbon monoxide discharge and remove residual carbon monoxide in tissues, but also increase oxygen The dissolved amount can reduce brain edema and relieve the inhibition of cytochrome enzyme.

Types of carbon monoxide poisoning:

1. Mild type

The poisoning time is short, and the carboxyhemoglobin in the blood is 10% --20%. It manifests as early symptoms of poisoning, including headache, dizziness, palpitations, nausea, vomiting, limb weakness, and even brief fainting. Generally, the symptoms disappear quickly after inhaling fresh air and leaving no sequelae.

2. Medium type

The poisoning time is slightly longer, and carboxyhemoglobin accounts for 30% to 40% in the blood. On the basis of mild symptoms, collapse or coma may occur. The skin and mucous membranes appear the cherry red color characteristic of gas poisoning. If rescued in time, people can wake up quickly and fully recover within a few days, usually without any sequelae.

3. Severe disease

If the patient is discovered too late, inhales too much gas, or inhales high concentrations of carbon monoxide in a short period of time, the blood carboxyhemoglobin concentration is often above 50%, and the patient Deep coma appears, various reflexes disappear, incontinence of urine and feces, cold limbs, blood pressure drops, shortness of breath, and death will occur quickly. Generally, the longer the coma lasts, the more serious the prognosis is, often leaving sequelae such as dementia, reduced memory and understanding, and limb paralysis.
