Abstract
Ce procédé consiste à canaliser l'air expiré (conduit 1) avec une vitesse minimale, à mesurer sa température (palpeur 2) de façon constante, à le diriger, lorsqu'une valeur de seuil préalablement fixée de la variation de la température dans le temps est dépassée vers le bas (comparateur 3), dans ou à travers une chambre de mesure 8, et à déterminer dans cette chambre, à l'aide de capteurs 9, la proportion du constituant gazeux à contrôler (par exemple de l'alcool) dans l'air alvéolaire. Grâce à ce procédé simple et fiable, on est assuré que la mesure porte uniquement sur la fraction d'air alvéolaire contenue dans l'air expiré.
