Antropometric Research on the Sizing of the MBU-20/P Aircrew Oxygen Mask
Abstract
The goal of this study was to determine sizing recommendation to improve the fit of the MBU-20/P Advanced Aircrew Oxygen Mask (AAOM). The approach was to do a fit test of the mask using the current sizes and the latest anthropometric measuring technology, then analyze the differences between subjects who passed and those who failed. This was done in conjunction with an effort to develop a customization process method for the soft rubber portion of the mask. This sizing study concentrates on improving the fit of the hard shell. The sizes currently available are SN (Small Narrow), MN (Medium Narrow), MW (Medium Wide), and LW (Large Wide). While it was hypothesized at the outset that the fit could be improved by adding a size, the fit results indicated that this was not the case. Instead, the location of the mask with respect to the face seemed to be an overriding factor.
