Abstract: Systems and methods are provided for etiologic-based breath simulation and/or ventilator test platforms that provide operator-configurable breathing patterns, patient respiratory muscular effort waveform characteristics and patient parameter values. According to one embodiment, multiple respiratory muscle effort waveform specifications, each of which have associated therewith one or more waveform parameters, are provided for use by a breathing effort generator. The waveform specifications include (i) a specification based upon an empirical model that approximates clinically-observed, patient-generated muscle pressures, (ii) a specification based on configurable etiology-driven templates and/or (iii) a specification based on a configurable piecewise trajectory template. A waveform engine of the breathing effort generator is configured in accordance with a selected waveform specification and corresponding waveform parameter values.

Abstract: There is provided a medical tube lumen plug, comprising: a plug, comprising: a body configured to be mechanically coupled to a lumen of a medical tube; and a protrusion configured to extend external to the medical tube, wherein the protrusion is configured to prevent occlusion of an aperture, wherein the aperture is configured to provide a pathway between the lumen and a region external to the medical tube.
