According to the Centers for Disease Control and Prevention, hundreds of people die each year from accidental carbon monoxide poisoning in the U.S., and thousands more are hospitalized. Between ...
Low level carbon monoxide poisoning leads to a wide range of nonspecific but significant symptoms – making it very difficult to detect. Low levels of carbon monoxide poisoning can be very ...
Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. [3] Symptoms are often described as " flu -like" and commonly include headache , dizziness , weakness, vomiting, chest pain , and confusion . [ 1 ]
Breathing in the fumes can make you sick, often causing fatigue, headaches and other flu-like symptoms. High levels of carbon monoxide can kill in minutes, according to the U.S. Environmental ...
As carbon monoxide binds with hemoglobin hundreds of times tighter than oxygen, it can prevent the carriage of oxygen. [68] Carbon monoxide poisoning can occur acutely, as with smoke intoxication, or over a period of time, as with cigarette smoking. Due to physiological processes, carbon monoxide is maintained at a resting level of 4–6 ppm.
Acute exposure can also lead to long-term neurological effects such as cognitive and behavioural changes. Severe CO poisoning may lead to unconsciousness, coma and death. Chronic exposure to low concentrations of carbon monoxide may lead to lethargy, headaches, nausea, flu-like symptoms and neuropsychological and cardiovascular issues. [9] [8] [10]
Common symptoms are often flulike and include headache, dizziness, upset stomach, chest pain or confusion, but highly concentrated levels of CO can cause a person to pass out without feeling symptoms.
Cerebral hypoxia refers to oxygen levels in brain tissue, not blood. Blood oxygenation will usually appear normal in cases of hypemic, ischemic, and hystoxic cerebral hypoxia. Even in hypoxic hypoxia blood measures are only an approximate guide; the oxygen level in the brain tissue will depend on how the body deals with the reduced oxygen ...
