Abstract
L'invention concerne également un système utilisant une détection combinée d'électrocardiographie (ECG) et de photopléthysmographie (PPG) pour évaluer un volume de fluide intra-artériel. Le système utilise la moyenne d'impulsions similaires basées sur la précédente (n-1; n minus 1) durée d'onde d'impulsion R-à-R, et précédente à la précédente (n-2; n minus 2) durée d'onde d'impulsion R-à-R, pour déterminer l'état du fluide d'un patient et s'il est au-dessous ou au-dessus de l'hydratation intravasculaire optimale.
