Embodiment Construction

[0010] As used herein, "a" and "an" include plural referents unless the context clearly dictates otherwise. As used herein, the statement that two or more parts or components are "coupled" shall mean that said parts are joined or work together, directly or indirectly, that is, through one or more intermediate parts or components, As long as the connection occurs. As used herein, "directly coupled" means that two elements are in direct contact with each other. As used herein, "fixedly coupled" or "fixed" means that two components are coupled so as to move as one while maintaining a fixed orientation relative to each other.

[0011] The word "single" as used herein means that a component is created as a single piece or unit. That is, a component that includes multiple blocks that are created separately and then coupled together as a unit is not a "single" component or entity. As used herein, the statement that two or more parts or components "engage" each other shall mean tha...

Abstract

Methods and systems to treat Cheyne-Stokes respiration (CSR) and/or central sleep apnea (CSA) include monitoring retrograde breathing and detecting respiratory events. Based on the occurrences of certain respiratory events, a target volume of rebreathing is adjusted to reduce arousals as well as CSR/CSA.

Description

technical field [0001] The present disclosure relates to methods and systems for treating central sleep apnea in a patient (or "subject"). Background technique [0002] One commercial technique for treating subjects with tidal respiration (CSR) is servo ventilation. The servoventilator (or airway pressure device) provides respiratory support to (temporarily) compensate for the subject's lack of breathing attempts (or reduced levels of subject's attempts). Use of servo ventilation may cause awakenings and hyperventilation. Contents of the invention [0003] It is an object of one or more embodiments of the present disclosure to provide a system for treating central sleep apnea in a subject using the cumulative retrograde volume of breathable gas at or near the airway of the subject . The system includes: one or more sensors that generate an output signal related to a parameter of the breathable gas at or near the airway of the subject; a respiratory event module configur...
