Abstract

Die Erfindung betrifft Verfahren und eine Anordnung zur Volumenreduktion der Lunge eines Patienten. Ein Bronchialkatheter (2) wird in ein überblähtes Lungenareal eingeführt und von dort mittels einer Absaugvorrichtung (3) Luft abgesaugt. Anschließend wird der zuführende Segmentbronchus verschlossen. Erfindungsgemäß wird die Spontanatmung des Patienten durch Sensoren (5) erfasst und die Absaugung der Luft synchron mit dem Einatmungsvorgang des Patienten durchgeführt. Um ein Kollabieren des zuführenden Segmentbronchus zu vermeiden, ist ein Druckerzeuger vorgesehen, mit dem der zuführende Segmentbronchus synchron zur Absaugung durch einen Druckgasimpuls aufgeweitet werden kann. Der Druckerzeuger kann in Abhängigkeit vom abgesaugten Luftstrom aktiviert werden, welcher mit einer Messvorrichtung überwacht wird.
