When infected with Covid-19, some patients will experience silent hypoxia, meaning that the oxygen saturation in the blood decreases but the patient still feels completely healthy and has no difficulty breathing. Therefore, measuring the oxygen concentration in the blood will help patients detect this condition early and intervene promptly.

The clinical symptoms of CO poisoning are very different and mostly non-specific. CO affects the transport of oxygen because the CO gas molecule binds too tightly to the Hemoglobin molecule, taking up the Hemoglobin's oxygen-binding site, resulting in the oxygen not being transported to the tissue cells by the Hemoglobin.

When you smoke, carbon monoxide, a poisonous gas, replaces some of the oxygen in your blood and affects your baby. Carbon monoxide (CO) is a colorless, odorless, and tasteless poisonous gas. You can't see it or smell it, but it's present in cigarette smoke. CO is also present in faulty gas stoves and car exhaust.

CO poisoning or coal smoke poisoning is a poisoning caused by inhaling carbon monoxide (CO) gas, which is quite common and occurs in many people. Carbon monoxide is a colorless, odorless gas but is extremely dangerous to humans. People with CO poisoning, if not detected and treated promptly, will be in great danger of death.
