METHOD FOR ESTIMATING A STATE OF ALERTNESS AND CONSCIOUSNESS IN RELATION TO A PERCENTAGE OF CARBOXYHAEMOGLOBIN IN BLOOD

摘要

The present invention describes a method for estimating the state of alertness and consciousness in relation to a percentage of carboxyhaemoglobin (COHb) in the blood of persons who work in enclosed spaces and are exposed to intoxication by carbon monoxide (CO) gas. The method integrates CO sensors and presence sensors for detecting persons exposed to levels of said gas that are higher than the authorised limits. An embedded system that includes said sensors executes an algorithm for estimating the level of COHb in blood by using a predetermined database to compare values with the obtained values.
