Abstract
L'invention concerne un dispositif et un système ainsi qu'un procédé permettant la détection de bulles de gaz qui se produisent naturellement dans la circulation sanguine; selon un mode de réalisation, un dispositif optique sans fil peut être placé sur diverses parties du corps comprenant un doigt ou un lobe d'oreille ou est couplé avec l'embout buccal d'un scaphandre autonome et détecte certains signes vitaux tels que le rythme cardiaque, la saturation en oxygène dans le sang (Sp02) et le rythme respiratoire par analyse du photopléthysmogramme (PPG) à partir d'un capteur miniature. L'invention concerne également un procédé et un appareil permettant une surveillance optique en temps réel et non invasive de l'état actuel du mal de décompression. Le procédé est basé sur des mesures simultanées de signaux PPG à différents endroits du corps humain et sur l'analyse d'un facteur tel que des déphasages entre différents endroits, le changement de la forme du signal PPG entre différents endroits, l'existence et la modification de lentes tendances et des modulations basse fréquence et des distributions angulaires de la lumière réfléchie.
