Resistência ao fluxo de gases através das cânulas de intubação de dupla luz

Abstract

Resistive patterns of 37 FR and 7,5 mm tubes were very similar. Any double lumen branch occlusion significantly increases resistance, however in a similar way for both branches for flows below 0.5 L.s-1. These results suggest the use of low inspiratory flow to minimize ventilatory system resistive pressure when any branch of a double-lumen tube is occluded.
