Abstract

La présente invention concerne l'unité centrale (40) d'un dispositif de mesure de la pression artérielle (1) qui mesure une température ambiante à l'aide d'une section de mesure de température (50) et qui détermine si la température ambiante se trouve ou non dans un environnement recommandé déterminé par une valeur seuil prédéfinie. Lorsque la température ambiante se trouve dans l'environnement recommandé, l'unité centrale calcule la pression artérielle en fonction d'une variation, mesurée par un capteur de pression (23), dans la pression interne d'un brassard (13).
