Systems and methods are described for calculating, in real-time, various oxygenation parameters including total oxygen transport (DO 2), mixed venous blood oxygen tension (RO 2) and mixed venous blood oxyhemoglobin saturation (SvO 2) in a patient. The system preferably uses a computer (140), an arterial pressure line (160) and a blood chemistry monitor (150) to assist a physician in accurately determining when to give a patient a blood transfusion or otherwise alter the clinical management of the patient.

L'invention porte sur des systèmes et des procédés de calcul, en temps réel, effectués sur un patient, de divers paramètres d'oxygénation tels que le transport (DO 2) total en oxygène, la tension (RO 2) en oxygène du sang veineux mélangé et la saturation (svO 2) en oxyhémoglobine du sang veineux mélangé. Ce système utilise de préférence un ordinateur (140), une conduite (160) de pression artérielle et un contrôleur (150) du profil biochimique qui permettent au médecin de déterminer avec précision à quel moment il faut effectuer une transfusion sanguine sur le patient ou alors modifier la conduite du traitement clinique sur ce dernier.
