#Carbon dioxide poisoning dry ice portable

reported a fatal case of carbon dioxide poisoning caused by dry ice that was being used for cooling while a refrigerator was being repaired. There were eight casualties, including two fatalities. In 1958, Williams described an incident of accidental carbon dioxide poisoning caused by onions in a cargo ship. However, since the early 1900s, there have been intermittent reports of accidental or intentional carbon dioxide poisoning. The dangers of carbon dioxide due to its daily industrial utilization, are not widely recognized and are easily overlooked. The patient was transferred to a neighboring hospital on the seventh day of his hospitalization. As the patient’s mental function had not improved, his family requested that he be transferred to another hospital for supportive care. A follow-up EEG, done 6 days after his admission showed no significant interval change ( Fig. After starting antibiotics, C-reactive protein level soon decreased to within the normal range.

C-reactive protein levels, measured daily for patient monitoring, gradually increased. A chest radiograph, taken the same day revealed increased haziness in the left lower lung field, indicating the presence of pneumonia ( Fig. Diffusion magnetic resonance imaging, performed two days later, showed that he had hypoxic brain damage ( Fig.

A portable EEG, done three days after the patient’s ICU admission, showed severe diffuse cerebral dysfunction ( Fig. EEG and diffusion magnetic resonance imaging were recommended after neurology department consultation a few days after ICU admission. He was admitted to the intensive care unit (ICU) under the care of the pulmonology department. After consulting with a neurologist, the patient underwent a portable electroencephalogram (EEG), which showed generalized epilepsy ( Fig. This cardiac arrest could have been avoided if the patient had been fully aware of the hazardous effects and serious consequences of exposure to high concentrations of carbon dioxide.Įven though the patient recovered spontaneous circulation within 26 minutes, he failed to restore his mental function in the emergency department, and started showing jerking movements, which raised the possibility of a seizure from carbon dioxide toxicity or hypoxic brain damage. Here we describe a case of carbon dioxide poisoning following an explosion of a carbon dioxide tank, which led to cardiac arrest. However, only a limited number of cases of carbon dioxide poisoning have been reported in Korea, and all these reports have been of mild intoxication. In Western societies, there have been case reports of carbon dioxide intoxication that has led to cardiac arrest. At higher concentrations, carbon dioxide can cause an instantaneous loss of consciousness and respiratory arrest because it acts both as an asphyxiant, and a toxicant. These symptoms can range from mild, such as headache, dizziness, and drowsiness, to severe, such as loss of consciousness, visual disturbances, and hearing difficulties. Victims of carbon dioxide exposure may experience a wide range of symptoms. Air containing 40,000 ppm of carbon dioxide poses an immediate threat to human life and health. The National Institute for Occupational Safety and Health recommends that short-term occupational exposure should not exceed 30,000 ppm over a period of fifteen minutes. However, exposure to high concentrations of carbon dioxide can have serious consequences. At low concentrations, carbon dioxide exposure does not cause any symptoms. A possible result of carbon dioxide accumulation is what is known as confined space hypoxic syndrome, in which the atmospheric deficit of oxygen can cause life-threatening conditions. Carbon dioxide has a molecular weight that is heavier than that of oxygen, and so it may accumulate if it is released in enclosed environments. Carbon dioxide, the fourth most common gas in the atmosphere, is widely produced and utilized by many industries for purposes such as refrigeration, fire suppression, and as a solvent.
