The percent saturation of carbon monoxide poisoning is always 34 percent. True or False?

Answer;

The above statement is false.

Explanation;

-When carbon monoxide replaces oxygen in the blood, a condition known as carboxyhemoglobin (COHb) saturation occurs.

-As more carbon monoxide accumulates in the blood, the percentage of COHb gets higher.

-Carbon monoxide detectors sound an alarm when the concentration of CO in the air corresponds to 10% carboxyhemoglobin level in the blood.

-This is because 10% COHb is at the very low end of CO poisoning.
