What is carbon monoxide poisoning?
Carbon monoxide poisoning is inhalation through the respiratory tract when the products of incomplete combustion of carbon-containing substances occur. Carbon monoxide is easy to combine with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its oxygen-carrying ability and effect, causing tissue suffocation. It has a toxic effect on tissue cells throughout the body, especially on the cerebral cortex. The use of carbon fires, gas and other combustibles in poorly ventilated environments can easily lead to carbon monoxide poisoning.
What are the symptoms of carbon monoxide poisoning?
Mild poisoning: symptoms such as headache, dizziness, palpitations, nausea, vomiting, palpitations, and weakness of the limbs.
Moderate poisoning: chest tightness, shortness of breath, dyspnea, hallucinations, blurred vision, flushing, excessive sweating, irritability, gradual coma.
Severe poisoning: coma, respiratory depression, pulmonary edema, arrhythmias, or heart failure develop rapidly, and patients may present with decortication syndrome.
