Therapy
Elimination The supreme objective is the elimination of carbon monoxide from the organism, in order to avert acute and long-term sequelae. The treatment should be continued until the COHb measurement has dropped to normal values (<3%) and the patient is free from symptoms (25).
Self-care
Plus, if multiple patients are affected by carbon monoxide exposure, only one at a time can be treated in the hyperbaric chamber. While there is clear evidence that hyperbaric oxygen therapy clears carbon monoxide from the blood faster, there is little evidence that patients are better off because of it.

For what purpose carbon monoxide is used?
Uses. Carbon monoxide is used in industry primarily as a source of energy and as a reducing agent. Both producer and water gas are burned as fuels for a variety of industrial operations. As a reducing agent, carbon monoxide is used to convert the naturally occurring oxide of a metal to the pure metal.
Why is carbon monoxide used in metallurgy?
Carbon monoxide is a strong reducing agent and reduces metal oxides for metals less reactive than carbon.
How does carbon monoxide treatment work?
This therapy involves breathing pure oxygen in a chamber in which the air pressure is about two to three times higher than normal. This speeds the replacement of carbon monoxide with oxygen in your blood. Hyperbaric oxygen therapy may be used in cases of severe carbon monoxide poisoning.
Why is carbon monoxide so reactive?
While the molecular nitrogen has a triple bond and neutral charge (elements which, in the presence, make it less reactive), the carbon monoxide has a very similar bond to a triple bond but also has a charge separation. This greatly enhances the reactivity of the molecule.
Why does carbon monoxide cause a triple bond?
Carbon and oxygen together have a total of 10 electrons in the valence shell. Following the octet rule for both carbon and oxygen, the two atoms form a triple bond, with six shared electrons in three bonding molecular orbitals, rather than the usual double bond found in organic carbonyl compounds.
Does CO displace oxygen?
Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain and other vital organs of oxygen. Large amounts of CO can overcome you in minutes without warning — causing you to lose consciousness and suffocate.
What are the effects of carbon monoxide?
Carbon monoxide is harmful because it binds to hemoglobin in the blood, reducing the ability of blood to carry oxygen. This interferes with oxygen delivery to the body's organs. The most common effects of CO exposure are fatigue, headaches, confusion, and dizziness due to inadequate oxygen delivery to the brain.

While there is clear evidence that hyperbaric oxygen therapy clears carbon monoxide from the blood faster, there is little evidence that patients are better off because of it.
Does hemoglobin bind to carbon monoxide?
Hemoglobin loves carbon monoxide and binds to it about 230 times stronger than it does to oxygen, which is a problem since carbon monoxide does not provide any benefit to the body. It doesn't take much carbon monoxide in the air you breathe to get carbon monoxide poisoning and it takes a lot of oxygen to get rid of it, ...
What is the source of carbon dioxide?
Carbon dioxide gas is produced during some fermentation processes such as wine-making, Natural sources account for the majority of CO2 released into the atmosphere, These include oceans, animal (and human) and plant respiration, decomposition of the organic matter, the forest fires, & emissions from volcanic eruptions.
Can CO poisoning cause nausea?
The people are at risk of CO poisoning, Unborn babies, infants, the elderly, and people with chronic heart disease, anemia, or respiratory problems are generally more at risk than others, Breathing CO can cause a headache, dizziness, vomiting, and nausea, If carbon monoxide levels are high enough, you may become unconscious or die. ...

What are the symptoms of CO poisoning?
Also note the 1 recurrent theme that is most significant in the recognition of CO poisoning - headache, dizziness and nausea. These 'flu like' symptoms are often mistaken for a real case of the flu and can result in delayed or misdiagnosed treatment. When experienced in conjunction with a the sounding of a CO these symptoms are the best indicator that a potentially serious buildup of CO exists. This comment will be returned to later.
What happens when you inhale CO?
When CO is inhaled, it combines with the oxygen carrying hemoglobin of the blood to form carboxyhemoglobin. Once combined with the hemoglobin, that hemoglobin is no longer available for transporting oxygen.
