When eating hot pot coal, be sure to pay attention to indoor ventilation. In addition, residents with conditions can install carbon monoxide alarms in kitchens, bedrooms and all areas with carbon monoxide sources.
3. Carbon monoxide poisoning will also occur in the car. When the car is parked, the driver should not rest in the car with the air conditioner on for a long time. If it is necessary to rest in the car, open the window to ventilate.
Typical symptoms of carbon monoxide poisoning
Light: the poisoning time is short, and the carbohemoglobin 10% ~ 20% in the blood. It manifests as early symptoms of poisoning, such as headache, dizziness, palpitation, nausea, vomiting, limb weakness, and even fainting for a short time. Generally, the mind is still clear. Inhale fresh air, and after leaving the poisoned environment, the symptoms will soon disappear, generally leaving no sequelae.
Medium-sized: the poisoning time is a little longer, and the carbon hemoglobin in the blood accounts for 30% ~ 40%. On the basis of mild symptoms, collapse or coma may occur. The skin and mucous membrane show cherry red peculiar to gas poisoning. If the rescue is timely, you can wake up quickly and fully recover within a few days. There are generally no sequelae.
Severe: found too late, inhaled too much gas, or inhaled high concentration of carbon monoxide in a short time, and the blood concentration of carboxyhemoglobin is often above 50%. The patient showed deep coma, various reflexes disappeared, incontinence, cold limbs, decreased blood pressure, shortness of breath and imminent death. Generally, the longer the coma, the more serious the prognosis, and the sequelae such as dementia, decreased memory and understanding, and limb paralysis often appear.
Other symptoms
Some patients with acute carbon monoxide poisoning will fall into coma again after 2-30 days' false recovery period, and have mental and neurological sequelae such as dementia, paralysis agitans syndrome, sensorimotor disorder or peripheral neuropathy, which is also called delayed encephalopathy caused by acute carbon monoxide poisoning. Long-term exposure to low-concentration carbon monoxide can cause headache, dizziness, memory loss, inattention and palpitation.
complication
Pulmonary fever, pulmonary edema, heart disease, etc. may be complicated in the course of this disease.
What about gas poisoning?
Let the patient leave the poisoned environment as soon as possible, and immediately open the doors and windows for ventilation.
Patients should rest quietly, so as not to increase the burden of heart and lung and increase the consumption of oxygen after exercise.
Breathe spontaneously and give adequate oxygen inhalation.
The unconscious poisoned patient must be carried out of the poisoned environment as soon as possible, and the patient's breathing, pulse and blood pressure should be checked in the shortest time, and first aid should be given according to these conditions.
Respiratory heartbeat stops, and artificial respiration and cardiac compression are performed immediately.
Call 120 emergency service, and the emergency doctor will go to the scene to treat the patient.
After the condition is stable, the patient will be escorted to the hospital for further examination and treatment.
Hyperbaric oxygen chamber treatment as soon as possible to reduce sequelae. Even if it is mild or moderate, hyperbaric oxygen chamber treatment should be carried out.
