Symptoms of furnace poisoning?

summary

Carbon monoxide poisoning, also known as gas poisoning. Carbon monoxide is a colorless, odorless, tasteless gas, so it is easy to ignore and cause poisoning. Common in the case of poor ventilation in the family room, coal gas or liquefied gas pipeline leakage or industrial production gas and carbon monoxide inhalation in the mine caused poisoning. Symptoms of furnace poisoning? Let's talk about it

Symptoms of furnace poisoning?

The main clinical manifestation is hypoxia, and its severity is proportional to the saturation of HbCO. Mild patients had headache, weakness, vertigo, dyspnea during labor, and the saturation of HbCO was 10% - 20%. The patient's lips were cherry red, nausea, vomiting, unconsciousness, collapse or coma, and the saturation of HbCO was 30% - 40%.

Severe cases were deep coma, accompanied by high fever, limb muscle tone enhancement and paroxysmal or tonic spasm, HbCO saturation > 50%. Patients with brain edema, pulmonary edema, myocardial damage, arrhythmia and respiratory depression, can cause death. Blisters and redness may appear on the skin of the chest and limbs in some patients, mainly due to autonomic dystrophy.

Some patients with acute carbon monoxide poisoning will be comatose again after 2-30 days of false recovery, and appear dementia, numbness type psychosis, tremor paralysis syndrome, sensory motor disorders or peripheral neuropathy and other mental and neurological sequelae, also known as acute carbon monoxide poisoning delayed encephalopathy. Long term exposure to low concentration of CO can lead to headache, dizziness, memory loss, inattention and palpitation.

matters needing attention

It should be widely publicized that there should be safety settings (such as chimney, small ventilation window, air funnel, etc.) when indoor coal fire is used, to explain the possible symptoms of gas poisoning and first-aid knowledge, especially to emphasize the harm and severity of gas to infants. The installation of coal stove chimney should be reasonable. The coal stove without chimney should be placed outdoors at night.
