Zusammenfassung
Die Ganzkörperplethysmographie stellt ein zuverlässiges Verfahren zur Bestimmung des intrathorakalen Gasvolumens und des Strömungswiderstandes in den Atemwegen dar. Das Verfahren ist auch schwerkranken Patienten zumutbar. Die Ergebnisse sind gut reproduzierbar. Untersuchungen lassen sich auch an einem Tag wiederholt beim gleichen Patienten ohne wesentliche Belästigung durchführen. Bei Patienten mit erhöhten Strömungswiderständen kommt es zu typischen Schleifenbildungen der Druckströmungsbeziehung. Diese Resistanceschleifen geben einen guten Einblick in die Dynamik der Spontanatmung. Die Deutung der verschiedenen Kurvenformen wird besprochen. Homogene und inhomogene Obstruktionen sowie Druck-Strömungsgeschwindigkeits-Phasenwinkel lassen sich aus den Kurvenformen leicht ableiten.
Summary
The bodyplethysmography presents a reliable method to determine the intrathoracic gas volume and the flow resistance in the airways. The method is also applicable in case of seriously ill patients. The results are well reproducible. It is possible to carry out repeatedly examinations on the same patient on one day too without essential inconvenience for him. In patients with increased flow resistances it comes to typical loop formations of the pressure flow relation. These resistance loops give a good insight into the dynamics of spontaneous breathing. The interpretation of the different curve shapes is discussed. Homogeneous and inhomogeneous obstructions as well as pressure flow velocity phaes angles can be easily derived from the shapes of the curves.
