Abstract

EN EL PROCEDIMIENTO PROPUESTO DE DETECCION DE SEÑALES PARASITAS PROVOCADAS POR MOVIMIENTOS DEL PACIENTE Y DE SU ENTORNO DURANTE LA MEDICION PULSOXIMETRICA DE LA SATURACION CON OXIGENO DE LA SANGRE ARTERIAL, LA INTENSIDAD DE LA LUZ EMERGENTE DEL OBJETO DE MEDICION SE MIDE MEDIANTE DOS FOTODIODOS (7, 8). LAS SEÑALES (S 1 , S 2 ) GENERADAS EN ESTOS FOTODIODOS (7, 8) SERAN NORMALIZADAS EN EL MISMO NIVEL DE SUS PARTES DE DC. FINALMENTE, PARA DETECTAR LAS SEÑALES PROVOCADAS POR MOVIMIENTO, SE DETERMINARAN LAS DIFERENCIAS ( DL S N ) DE ESTAS SEÑALES NORMALIZADAS (S 1N , S 2N ).
