Embodiment Construction

[0015] As used herein, the singular forms "a", "an" and "the" 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 the parts are connected directly or indirectly (i.e., through one or more intermediate parts or components, so long as a connection is made). ) are joined together or operated together. 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.

[0016] As used herein, the word "unitary" means that a component is created as a single piece or unit. That is, a component that includes pieces that are created separately and then coupled together as a unit is not a "unitary" component or entity. As used herein, the statement that two or more parts or ...

Abstract

A pressure support system includes a pressure generating system structured to generate a flow of breathing gas, a patient circuit including a patient interface device, wherein the patient circuit is coupled to the pressure generating system and is structured to carry the flow of breathing gas, a barometric pressure sensor coupled to the patient circuit within a gas flow path of the patient circuit, wherein the barometric pressure sensor is structured to generate a barometric pressure signal indicative of a barometric pressure within the gas flow path proximate the patient, and a control system. The control system is structured to control the outlet pressure of the pressure generating system based on at least the barometric pressure signal in a manner that compensates for a pressure drop across the patient circuit due to a pneumatic resistance of the patient circuit.

Description

technical field [0001] The present invention relates to airway pressure support devices, and in particular to positive airway pressure support devices and associated methods employing baromatric pressure sensors in the airflow path to compensate for variable resistance in a patient circuit. Background technique [0002] Many individuals suffer from breathing disturbances during sleep. Sleep apnea is a common example of such a sleep-breathing disorder suffered by millions of people worldwide. One type of sleep apnea is obstructive sleep apnea (OSA), which is a condition in which sleep is repeatedly interrupted due to obstruction of the airway (usually the upper airway or pharyngeal area) resulting in inability to breathe. It is generally believed that airway obstruction is at least in part due to a general relaxation of the muscles that stabilize the upper airway segment, allowing the tissue to collapse the airway. Another type of sleep apnea syndrome is central apnea, whic...
