Symptoms of carbon dioxide poisoning

Acute poisoning rarely has conjunctival and oropharyngeal mucosa irritation symptoms. The initial patients often do not know that they have been poisoned. The degree of lung injury depends on the gas concentration and inhalation time. After exposure to more than 150 mg / m3 nitrogen dioxide for 3-24 hours, respiratory symptoms appear, such as cough, fever, shortness of breath, bloody sputum, extreme weakness, nausea and headache, Bronchospasm is the main characteristic of acute stage. Rales and wheezes can be heard in chest auscultation. Laboratory examination showed that peripheral blood leukocytes and neutrophils increased. Arterial blood gas showed that Alveolar arterial oxygen partial pressure increased. At the beginning, chest film was normal and pulmonary edema gradually appeared.

No2 poisoning is characterized by long incubation period and delayed pulmonary edema. Chest X-ray showed that both lungs were covered with miliary shadows.

Nitrogen dioxide is very harmful to human body and will cause great damage to lung function; If exposed to nitrogen dioxide for a long time, the chance of respiratory tract infection will increase, and may lead to permanent organic lung disease. Therefore, when people are found to have symptoms of nitrogen dioxide poisoning, they must be sent to the hospital in time to avoid delaying the best time for treatment.
