Résumé
L'emploi de la fibrobronchoscopie permet actuellement d'étudier quelques caractéristiques fonctionnelles du poumon, telles la clairance muco-ciliaire et certains aspects de la fonction pulmonaire régionale (lobaire ou segmentaire).
Dans le premier cas, par fibrobronchoscopie, on mesure la vitesse de déplacement de petits disques de téflon posés sur la surface broncho-trachéale; dans le deuxième cas, la méthode consiste à prélever des gaz respiratoires au niveau lobaire ou segmentaire de façon à suivre à tout instant, au cours du cycle respiratoire complet, les variations de concentration des gaz et d'obtenir des informations sur le comportement fonctionnel d'un secteur parenchymateux déterminé.
Summary
Recently, the use of fiberbronchoscopy led to the study of some of the functional features of the lung, such as muco-ciliany clearance and some aspects of the regional pulmonary function (lobar or segmentary).
In the first case, fiberbronchoscopy makes it possible to study the motion speed of small teflon disks on the bronchal-tracheal surface; in the second case, it makes sampling of respiratory gases possible at lobar or segmentary level so that changes in gas concentration can be followed at any time during the whole respiratory cycle, in order to collect information on the functional behaviour of a given parenchymatous sector.
