Abstract
L'invention porte sur un ensemble de ventilation formé d'un ventilateur médical (25) et d'un humidificateur de gaz (24). On utilise un premier capteur de température (13) pour mesurer la température de l'élément chauffant (7) de l'humidificateur (24) et un second capteur de température (12) pour mesurer la température de la première plaque chauffante (6) du boitier (14) de l'humidificateur (24). Des moyens de commande (20, 22) comprenant un processeur (22) mettant en œuvre un algorithme permettent de déterminer lorsque le réservoir (4) est vide d'eau à partir de signaux de mesure provenant des premier et second capteurs de température (12, 13) et du signal de commande de chauffe provenant des moyens de commande (20, 22).
