Abstract
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.

MÉTODO DE ESTIMACIÓN DE ESTADO DE ALERTA Y CONCIENCIA EN RELACIÓN A PORCENTAJE DE CARBOXIHEMOGLOBINA EN LA SANGRE METHOD OF ESTIMATING STATE OF ALERT AND CONSCIOUSNESS IN RELATION TO PERCENTAGE OF CARBOXYHEMOGLOBIN IN THE BLOOD
CAMPO TÉCNICO DE LA INVENCIÓN TECHNICAL FIELD OF THE INVENTION

The present invention has its preponderant field of application in safety practices and protocols in the Mining Industry, specifically where activities are carried out in confined spaces with a risk of poisoning due to the presence of Carbon Monoxide in the environment.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
El monóxido de carbono (CO) es un gas invisible, inodoro, incoloro, insípido, inflamable y altamente tóxico, que se desprende cuando se queman materiales combustibles de forma incompleta o con poco aporte de oxígeno. Este gas procede de materiales como madera, carbón de leña, carbón mineral, tabaco, gas natural, gasoil, queroseno, gasolina, butano y propano. Sus características le hacen muy difícil de detectar con los sentidos del cuerpo humano, siendo los primeros síntomas de advertencia y más frecuentes que indican la presencia de CO en el aire, suelen ser dolores de cabeza, mareos, náuseas, vómitos y debilidad muscular. Este gas puede incluso causar el fallecimiento de un ser vivo cuando se respira incluso en cantidades moderadas, por envenenamiento en pocos minutos, porque sustituye al oxígeno en la hemoglobina de la sangre. El CO se une a la hemoglobina de una manera hasta 250 veces más fácilmente que con el propio oxígeno. Se produce el compuesto denominado COHB o carboxihemoglobina, que resulta unas 200 veces más difícil de separar que el compuesto de la hemoglobina con el oxígeno. Bloquea la capacidad de la sangre para transportar oxígeno y da lugar a una grave lesión del pulmón y el cerebro, llegando incluso a causar la muerte. En actividades de minería subterránea, los trabajadores se encuentran expuestos a diferentes tipos de gases en especial monóxido de carbono, estos son generados por las condiciones propias de la extracción de minerales como la utilización de máquinas de combustión interna. Se requieren herramientas que cuenten con la capacidad no sólo de detectar e
informar el valor de CO en tiempo real al sistema de control, sino que cuenten con algoritmos que estimen las condiciones de los trabajadores sin la necesidad de medios invasivos de sensado, con el fin de establecer procedimientos de evacuación específicos en caso de ser requerido. Carbon monoxide (CO) is an invisible, odorless, colorless, tasteless, flammable and highly toxic gas, which is released when combustible materials are burned incompletely or with little oxygen supply. This gas comes from materials such as wood, charcoal, mineral coal, tobacco, natural gas, diesel, kerosene, gasoline, butane and propane. Its characteristics make it very difficult to detect with the senses of the human body, being the first and most frequent warning symptoms that indicate the presence of CO in the air, usually headaches, dizziness, nausea, vomiting and muscle weakness. This gas can even cause the death of a living being when you breathe even in moderate amounts, by poisoning in a few minutes, because it replaces the oxygen in the blood hemoglobin. CO binds to hemoglobin in a way up to 250 times more easily than with oxygen itself. The compound called COHB or carboxyhemoglobin is produced, which is about 200 times more difficult to separate than the hemoglobin compound with oxygen. It blocks the ability of blood to transport oxygen and results in a serious injury to the lung and brain, even causing death. In underground mining activities, workers are exposed to different types of gases, especially carbon monoxide, these are generated by the conditions of mineral extraction such as the use of internal combustion machines. Tools are required that have the ability not only to detect and Inform the value of CO in real time to the control system, but have algorithms that estimate the conditions of the workers without the need for invasive sensing means, in order to establish specific evacuation procedures if required.
