title: Effects on respiratory patterns during bronchoscopy by the Sanders attachment technique.
abstract: The purpose of this study was to rationalize the choice of injector and bronchoscope sizes during bronchoscopy under general anesthesia using the Sanders attachment technique. Arterial Po2 and Pco2, FIo2, and peak inspiratory pressure at the tip of the bronchoscope were plotted against the ratio (RI/B) of the internal diameters of the injector and the bronchoscope in seven dogs undergoing bronchoscopy under general anesthesia. Peak inspiratory pressure, FIo2, and PaO2, increased, and PaCO2 decreased with an increase in RI/B. A working table is proposed to predict the optimal RI/B.
