Abstract
Official abstract text for this publication.
A CPAP apparatus has a variable rise time (iii) from a base level of positive air pressure during expiration (EPAP) to a higher level during inspiration (IPAP). The rise time is adjusted in order to reduce obstruction, resistance or instability in the upper airway.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of control for a ventilator having a flow generator, the method comprising: controlling the flow generator to generate a flow of breathable gas, the control of the breathable gas being characterized by an expiratory pressure and a higher inspiratory pressure, the control of the breathable gas being further characterized by a rate of change of the expiratory pressure to the higher inspiratory pressure; detecting an event of upper airway insta…
