Carbon monoxide poisoning. 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] Large exposures can result in loss of consciousness, arrhythmias, seizures ...
Infobox references. Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide.
When a patient presents with carbon monoxide poisoning (CO) or other non-respiratory hypoxic symptoms, most current CO-oximeters will detect the relative levels of each hemoglobin fraction (oxyhemoglobin and dyshemoglobins) and likely the oxyhemoglobin saturation. For any system making these measurements it is critical that the device clearly ...
At higher levels, carbon monoxide exposure can be fatal. Other symptoms include: Impaired vision and coordination. Headaches. Dizziness. Confusion. Nausea.
Carbon monoxide poisoning, also known as carboxyhemoglobinemia, [29] [30] has plagued humankind since primitive ancestors first harnessed fire. In modern times, carboxyhemoglobin data assist physicians in making a poisoning diagnosis. However, carboxyhemoglobin levels do not necessarily correlate with the symptoms of carbon monoxide poisoning. [31]
Breath carbon monoxide device. Breath carbon monoxide is the level of carbon monoxide in a person's exhalation. It can be measured in a breath carbon monoxide test, generally by using a carbon monoxide breath monitor (breath CO monitor), such as for motivation and education for smoking cessation and also as a clinical aid in assessing carbon monoxide poisoning.
Chronic exposure to low concentrations of carbon monoxide may lead to lethargy, headaches, nausea, flu-like symptoms and neuropsychological and cardiovascular issues. [28] [26] The WHO recommended levels of indoor CO exposure in 24 hours is 4 mg/m 3. [29] Acute exposure should not exceed 10 mg/m 3 in 8 hours, 35 mg/m 3 in one hour and 100 mg/m ...
Acute Exposure Guideline Levels (AEGLs) set levels of chemical concentration that pose a defined level of risk to humans (the general population, including susceptible individuals). [1][2][3] These levels are used in preventing and responding to disasters. These guidelines are ascertained for one, short exposure (with a maximum of eight hours ...
