The present invention relates to a method and apparatus for monitoring haemodynamic function in animals and humans during anaesthesia and surgery. During anaesthesia and surgery the subject's haemodynamic, respiratory, neuromuscular and neurological functions are monitored as indicators of the condition of the health of the subject. Commonly, variations in blood pressure are used to imply corresponding variations in cardiac ouput, i.e. good blood pressure equals good cardiac output. The present invention utilises a device to monitor changes of blood flow in peripheral blood vessels of the subject as an indicator of cardiac output. This is believed to provide a much more accurate indicator.

L'invention a pour objet un procédé et un appareil pour contrôler la fonction hémodynamique chez l'animal et chez l'homme, pendant l'anesthésie et les interventions chirurgicales. En effet, au cours de l'anesthésie et des interventions chirurgicales, les fonctions hémodynamiques, respiratoires, neuromusculaires et neurologiques du sujet sont contrôlées comme paramètres indiquant l'état de santé du sujet. En général, les variations de la pression sanguine correspondent à des variations du débit cardiaque. En d'autres termes, une bonne pression sanguine est synonyme d'un bon débit cardiaque. La présente invention concerne un dispositif pour contrôler les changements de débit sanguin dans les vaisseaux sanguins périphériques du sujet comme indicateurs du débit cardiaque. Cela constitue un indicateur d'une précision bien supérieure.
