Question

Is Carboxyhemoglobin dangerous?

Answer 1

Hemoglobin is a protein that conducts oxygen from the lungs to the tissues while also bringing carbon dioxide from the tissues to the lungs. Carbon monoxide is a flammable gas that is transparent, tasteless, and odorless. When breathed in, it is dangerous because it slows down oxygen levels in the blood.

Complete answer:
Carboxyhemoglobin is formed when carbon monoxide reacts with haemoglobin. It also strengthens the link between oxygen and haemoglobin, making the haemoglobin molecule less capable of relinquishing oxygen bound to neighboring oxygen receptors. The total outcome is a decline in the rate of oxygen available to the body's tissues.
When compared to oxygen, carbon monoxide has a $240$-fold greater affinity for binding with hemoglobin. An elevation in carboxyhemoglobin levels triggers asphyxiation to varying degrees, including death. It does not dissociate readily. As a result, the oxygen carrying power of blood gets limited. A high level of carboxyhemoglobin in the blood is the cause of death in carbon monoxide poisoning. Thus, carboxyhemoglobin is dangerous.

Additional information:
Carbon monoxide gas dissipates quickly over the capillary membrane of the pulmonary vessels, binding to haemoglobin. CO limits the oxygen-carrying potential and oxygen supply to tissues by displacement of oxygen, leading to cellular hypoxia and acidosis. Several metabolic activities are substantially impacted by CO.

Note:
If we take in air that has too much carbon monoxide, we can become poisoned. Carbon monoxide poisoning can be determined with a carbon monoxide blood work. The blood test is conducted to investigate how much haemoglobin is bound with carbon monoxide. This is the measurement of carboxyhemoglobin.
