Abstract: A replaceable liner, for a respiratory mask comprising an elastic substantially tubular shaped body dimensioned to stretch around the mask cushion. The liner is made of a knitted fabric in radially-continuous tubular structure that is preferentially formed through a circular knit to create a seamless tube. The ends of the fabric tube may be hemmed, finished with a fabric or elastic welt, or otherwise finished to prevent unraveling of the knit. The seamless tubular body may be knitted from a variety of natural yarns, such as wool or cotton, or from synthetic yarns, such as nylon, polyester, spandex, or elastic, to achieve a balance of comfort and wicking of skin oils and moisture, while maintaining sufficient radial elasticity to stretch around the respiratory mask. The fabric may be treated with antimicrobial coatings to provide protection against bacteria, fungus and reduce propensity of odors/stains.

Abstract: Methods and apparatus treat a respiratory disorder. For example, a pressure generator supplies a flow of air at positive pressure to a patient's airway through a patient interface. A sensor generates a signal representing respiratory flow rate of the patient. A controller controls the pressure generator to provide to the patient interface a ventilation therapy having a base pressure. The controller computes a measure of ventilation of the patient from the signal. The controller computes a measure of flow limitation from an inspiratory portion of the signal. The controller computes a ratio of the measure of ventilation and an expected normal ventilation. The controller adjusts a set point for the base pressure of the ventilation therapy based on the measure of flow limitation. The adjustment may further depend on a comparison between the ratio and a relative ventilation threshold that increases as the measure of flow limitation increases.
