Moderate poisoningSymptoms such as hyperhidrosis, irritability, unstable walking, pale skin, blurred consciousness, feeling unable to wake up, drowsiness and fatigue, and gradually entering a coma state appear. If effective measures are taken, patients can basically be cured, leaving few sequelae. 3.Severe poisoningThe main symptoms are confusion, closed jaws, convulsions, incontinence, a cherry red complexion and lips, increased breathing and pulse, increased blood pressure, irregular heartbeat, lung rales (respiratory murmurs), and possible increase in body temperature; Extremely critical individuals can continue to experience deep coma, weak pulse, irregular breathing, decreased blood pressure, and even life-threatening conditions.

The concentration of carbon monoxide in the air will cause harm to human body: 1. The content of carbon monoxide in the air reaches 50ppm, and adults are allowed to be exposed to the large content of carbon monoxide. If the content exceeds this level, it will cause harm to the human body; 2. The content of carbon monoxide in the air reaches 200ppm. Adults will have mild headache, dizziness, nausea and other adverse symptoms after being exposed to it for 2-3 hours; 3. The content of carbon monoxide in the air reaches 400 ppm. Adults will suffer from forehead pain within 2 hours after exposure, and will be in danger of life after 3 hours; 4. The content of carbon monoxide in the air reaches 800 ppm. Adults have headache and nausea within 45 minutes and die within 2-3 hours; 5. The content of carbon monoxide in the air reaches 1600 ppm, causing headache and nausea within 20 minutes and death within 1 hour; It can be seen from the above data that as long as the content of CO in the air exceeds 50ppm, it will cause harm to human body. Once this range is exceeded, we need......

What should we do if we are harmed by carbon monoxide, a toxic gas, in our daily life? 1. Turn off the open fire at the first time After smelling the smell of gas, do not turn on the light, do not touch the doorbell, and do not light the open fire to prevent explosion. The rescue personnel shall ensure safety (cover mouth and nose with wet towel) and turn off the gas. 2. Get out of toxic environment Open the doors and windows of the closed room and let the patient breathe fresh air immediately; 3. Proper recumbent position (1) Immediately place the patient in a lateral position and loosen the patient’s collar to ensure that the respiratory tract is unobstructed and prevent suffocation; Closely observe the patient’s consciousness, breathing and pulse. If the patient’s breathing and heartbeat stop without assistance, the rescuer should call the emergency call in time while performing cardiopulmonary resuscitation to send the poisoned person to the hospital with hyperbaric oxygen chamber for rescue; (2) For patients who are unconscious, their heads can be turned to one side to prevent the vomit from being sucked into the lungs by mistake and causing asphyxia; We need......
