Carbon monoxide also binds to the hemeprotein myoglobin. It has a high affinity for myoglobin, about 60 times greater than that of oxygen. [21] Carbon monoxide bound to myoglobin may impair its ability to utilize oxygen. [49] This causes reduced cardiac output and hypotension, which may result in brain ischemia. [21]
Respiratory damage is related to the concentration of the gas and its solubility. Irritant gas exposures predominantly affect the airways, causing tracheitis , bronchitis, and bronchiolitis . Other inhaled agents may be directly toxic (e.g. cyanide , carbon monoxide ), or cause harm simply by displacing oxygen and producing asphyxia (e.g ...
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.
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.
Smoke inhalation is the breathing in of harmful fumes (produced as by-products of combusting substances) through the respiratory tract. [1] This can cause smoke inhalation injury (subtype of acute inhalation injury) which is damage to the respiratory tract caused by chemical and/or heat exposure, as well as possible systemic toxicity after smoke inhalation.
After the details of this suicide were highly publicised by local media, many others killed themselves in this way (an example of the Werther effect). Within two months, charcoal-burning had become the third major suicide killer in Hong Kong. [6] Charcoal-burning suicide accounted for 1.7% of Hong Kong suicides in 1998 and 10.1% in 1999. [7]
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. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...
An air quality monitor. Human exposure to aerosols has a variety of adverse health effects. [7] Building occupants complain of symptoms such as sensory irritation of the eyes, nose, or throat; neurotoxic or general health problems; skin irritation; nonspecific hypersensitivity reactions; infectious diseases; [8] and odor and taste sensations.
