Abstract

We analyse the stability of a regulated oxygen mask distributing oxygen in response to an inhalation demand. The mask pressure exhibits troublesome vibrations after the demand reaches a certain flow value. Starting from a simple nonlinear model, we perform a local linear stability analysis which highlights that the real part of two eigenvalues is positive when this system is chattering. We propose then adjustments of some parameters of this purely mechanical system in order to avoid this phenomenon. These adjustments have been tested and validated experimentally.
