Abstract

L'invention concerne un système de surveillance de l'oxygène dans le sang, lequel système a un processeur pour traiter une entrée provenant d'un dispositif de détecteur de lumière. Le processeur reçoit une entrée concernant un ou plusieurs paramètres spécifiques de patient et détermine une sortie sur la base de l'entrée du dispositif de détecteur de lumière et de l'entrée de paramètre spécifique de patient. L'entrée de paramètre de patient est utilisée pour modifier la sortie de système pour assurer une détermination plus précise de la saturation en oxygène. Le système peut être utilisé pour déduire des courbes R spécifiques du patient ou un facteur d'ajustement devant être appliqué à des donnés stockées existantes.
