Abstract
La oximetría de pulso es un método con el que se establece la saturación del oxígeno en sangre periférica en función de la determinación del nivel de absorción de luces rojas, al hacerlas incidir sobre la hemoglobina. Es una tecnología que está basada en la propiedad de la hemoglobina de presentar diferentes espectros de absorción según cuál sea su estado (oxigenado o reducido). Es, por tanto, una técnica de laboratorio no invasiva, no cruenta, que resulta una buena herramienta para el control continuo de la saturación de oxígeno en sangre periférica. Sin embargo, presenta ciertas restricciones y desventajas. Algunas se deben a la propia estructura y composición del aparato en sí, y otras a factores externos, entre los que se encuentran el movimiento o la hiperpigmentación de la piel. Su aplicación en la prueba de esfuerzo ha sido de reciente uso, utilizándose en ergometría en la clínica (especialmente en cardiología y neumología), y, en menor medida, en el ámbito de la medicina deportiva, donde se han encontrado interesantes resultados para el estudio de la condición física de los deportistas. La mayoría de los estudios llevados a cabo con pulsioximetría dentro del ámbito de la medicina deportiva y en la clínica se han realizado en poblaciones masculinas, encontrándose pocos trabajos centrados en mujeres. Estudios previos atribuyen limitaciones en el rendimiento físico de las mujeres deportistas a consecuencia de diferencias anatómicas y fisiológicas del sistema respiratorio. El objetivo de esta tesis ha sido determinar la saturación transcutánea de oxígeno en mujeres deportistas de distintas razas (negra y caucasiana) y analizar la correlación de dicha determinación con los umbrales ventilatorios aeróbico y anaeróbico...
Oximetry is a method used to assess peripheral blood oxygen saturation based on the determination of the level of red light absorption, directly influenced by the hemoglobin levels. This technology is based on the property of hemoglobin that shows different absorption spectra depending on its state (oxygenated or reduced). Pulse oximetry is a non-invasive laboratory technique, and a useful tool for continuous monitoring oxygen saturation in peripheral blood. However, it shows some limitations and disadvantages - some due to the structure and composition of the device itself, and others, a consequence of external factors such as movement or skin hyperpigmentation. Its application in stress tests has been recently used; mainly in the clinical setting (especially in cardiology and pulmonology), and to a lesser extent, in the field of sports medicine, where interesting results have been found in the study of athletes’ physical condition. Most studies carried out with pulse oximetry within the scope of sports medicine and in the clinic, have been carried out in male populations, with few studies seen in female populations. Some of these studies attribute limited physical performance to women, and suggest that the cause is due to anatomic and physiological in their respiratory system in comparison to men...
