Title and Subtitle: An improved method for determining the efficiency of crew passenger oxygen masks

Report Date: November 1962

Authors: McFadden EB, Raeke JW, Young JW

Abstract: A method for determining oxygen mask leakage as developed under contract FA-885 between the Federal Aviation Agency and the Pioneer-Central Division of the Bendix Corporation was evaluated. Measurement of nitrogen concentration within an oxygen mask following respiratory nitrogen washout appears to provide a valid index of inboard mask leakage. Further development of this technique and its application to a proposed mask design is described.
