How to prevent carbon monoxide poisoning?

1. Keeping air circulation is the key, and the key to avoid poisoning is to keep room air circulation; When the weather gets warmer and the air pressure is low, you must wait until the coal is completely burned out before going to sleep. Those who adopt central heating should also be vigilant, and water heaters and gas should not be placed in rooms where family members are active.

2, when eating hot pot with coal, be sure to pay attention to indoor ventilation. In addition, conditional residents can install carbon monoxide alarms in kitchens, bedrooms and all areas with carbon monoxide sources.

3. Carbon monoxide poisoning can also occur in the car. When the car is stopped, 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, the window should be opened for ventilation.

Typical symptoms of carbon monoxide poisoning

Mild: the poisoning time is short, and the carboxyhemoglobin in the blood is 1% ~ 2%. It is manifested as the early symptoms of poisoning, such as headache, dizziness, palpitation, nausea, vomiting, weakness of limbs, and even a short-term fainting. Generally, the mind is still awake. After inhaling fresh air and leaving the poisoned environment, the symptoms quickly disappear, generally leaving no sequelae.

moderate: the poisoning time is a little longer, with 3% ~ 4% of carboxyhemoglobin in the blood. On the basis of mild symptoms, you may collapse or coma. The skin and mucous membrane show cherry red peculiar to gas poisoning. If the rescue is timely, you can wake up quickly and recover completely within a few days. Generally, there is no sequelae.

severe: if it is found that the time is too late, too much gas is inhaled, or high concentration of carbon monoxide is inhaled in a short time, and the blood carboxyhemoglobin concentration is often above 5%, the patient will be in a deep coma, all kinds of reflexes will disappear, incontinence, cold limbs, blood pressure drop, shortness of breath, and will die soon. Generally, the longer the coma time, the more serious the prognosis, and there are often sequelae such as dementia, decreased memory and understanding, and limb paralysis.

other symptoms

after waking up from COma, some patients with acute co poisoning will be comatose again after a 2-3-day fake recovery period, and will have mental and neurological sequelae such as dementia, paralysis agitans syndrome, sensorimotor disorder or peripheral neuropathy, also known as delayed encephalopathy caused by acute carbon monoxide poisoning. Long-term exposure to low-COncentration co may cause headache, dizziness, memory loss, inattention and palpitation.

Complications

During the course of this disease, pulmonary fever, pulmonary edema, heart diseases and so on may be complicated.

what about gas poisoning?

Let the patient leave the poisoned environment as soon as possible, and immediately open the doors and windows to ventilate the air.

Patients should rest quietly to avoid aggravating the burden on the heart and lungs and increasing oxygen consumption after exercise.

have spontaneous breathing, 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 emergency treatment should be carried out according to these conditions.

when the breathing and heartbeat stop, artificial respiration and cardiac compression should be performed immediately.

call 12 emergency service, and the emergency doctor will go to the scene to treat the patient.

After the condition is stable, escort the patient to the hospital for further examination and treatment.

Try to carry out 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.
