What are the manifestations of carbon monoxide poisoningIn addition to "burning charcoal for heating", eating charcoal hot pot, barbecue, cooking tea around the stove in a relatively closed room, cooking with gas with doors and windows closed, blowing air conditioners in closed garages or parking windows, etc., may be the "culprit" of carbon monoxide poisoning.
Carbon monoxide poisoning, mild headache, dizziness, palpitations, limb weakness, nausea, vomiting, etc. Carboxyhemoglobin 10-30% in the blood.
Moderate poisoning manifests as impaired consciousness, shallow to moderate coma, convulsions and pathological reflexes. ** and mucous membranes have a cherry red color characteristic of gas poisoning. Carboxyhemoglobin in the blood 30-50%.
In severe poisoning, there is a deep coma, loss of various reflexes, incontinence, cold extremities, decreased blood pressure, shortness of breath, and generally death quickly. Carboxyhemoglobin > 50% in the blood. ”
Six myths about carbon monoxideThere may be some misunderstandings about carbon monoxide in daily life, which need to be paid attention to.
Myth 1: Only burning coal can cause poisoning
In fact, all carbon-containing fuels, whether they burn gasoline, kerosene, ordinary charcoal, or "environmentally friendly charcoal"!When there is a lack of oxygen and cannot be fully combusted, a large amount of carbon monoxide can be produced.
Myth 2: No soot and odor will not be poisoned
Carbon monoxide itself is colorless and odorless, it is difficult for people to detect, if the doors and windows are closed at this time to form a confined space, people are very easy to be poisoned by carbon monoxide inside. When burning charcoal at home for warmth, it should be extinguished and moved outside before bedtime.
Myth 3: Gaps in doors and windows will not be poisoned
The specific gravity of air is 1 and the specific gravity of carbon monoxide is 0967, if the gap between the door and window is low, carbon monoxide is not easy to discharge.
Myth 4: Installed chimneys or wind pipes will not be poisoned
Poisoning can also occur if the smoke is poured into the wind or the chimney is blocked, and the carbon monoxide is not emitted or the emission is small. However, many families use old air ducts, or the air ducts are too small, the installation height is not enough, etc., and the carbon monoxide discharge is not smooth, which can also cause poisoning.
Myth 5: Putting a basin of water by the stove can prevent poisoning
It has been scientifically proven that carbon monoxide is extremely insoluble in water and does not have a preventive effect.
Myth 6: After carbon monoxide poisoning**, the disappearance of symptoms is equivalent to complete recovery
Some patients with carbon monoxide poisoning may redevelop neuropsychiatric symptoms predominantly acute dementia after a period of several days or weeks of asymptomatic (pseudohealing) after the symptoms of acute poisoning have resolvedOr after the patient returns to normal consciousness in the acute phase, after a "false recovery period", the patient suddenly develops brain dysfunction. The above situation is called "late-onset encephalopathy of carbon monoxide poisoning", and patients should pay attention to it after being discharged from the hospital, and should seek medical attention immediately if a similar situation occurs.
When carbon monoxide poisoning is found, open doors and windows immediately, move the patient to a well-ventilated place with fresh air, and keep warm. Unbutton your clothes to keep your airway clear, and if you are delirious, tilt your head to one side to clear your mouth and nose secretions. If respiratory arrest is detected, rescue breaths should be performed immediately and external compressions should be done. Patients should remain quiet and restless to avoid activity that can increase oxygen consumption. For moderate to severe patients, at the same time as on-site first aid, 120 emergency should be called immediately** and sent to a hospital with a hyperbaric oxygen chamber as soon as possible**, through which the discharge of carbon monoxide can be promoted.
