Described is a system including an air pressure supply arrangement, a sensor and a titration device. The air pressure supply arrangement provides air pressure to a patient's airways. The sensor detects input data corresponding to a patient's breathing patterns of a plurality of breaths. The titration device receives and analyzes the input data to determine existence of breathing disorder and corresponding characteristics. The titration device generates output data for adjusting the air pressure supplied to the patient as a function of an index of abnormal respiratory events included in the input data.

A breathing assistance apparatus has a pressurised gases source featuring a lightweight impeller with a plastic shaft. The impeller is shroudless. The plastic shaft is supported within the stator by a bearing structure. The resilient motor mount couples the stator and the housing and provides compliance and/or damping for the motor.

Devices, systems, and methods are disclosed which permit ventilation therapy concurrent with humidity and aerosol drug delivery. Exemplary mixer-heaters employ alternating actuation of humidity and drug nebulizers and may use a single constant power setting for the heating section while keeping a controlled outlet temperature over the course of treatment.

A pressure support system for providing pressure support therapy to a patient, the pressure support device includes an airflow generator structured to generate a flow of breathing gas to the patient, a temperature conditioning unit structured to adjust a temperature of the breathing gas provided to the patient, and a processing unit structured to estimate a core body temperature of the patient for selected times of day based on one or more inputs and to control the temperature conditioning unit to adjust temperature of the breathing provided to the patient at the selected times of day based on the estimated core body temperatures of the patient.

Product manifolds for use with portable oxygen concentrators and portable oxygen concentrators including such product manifolds. A product manifold for use with a portable oxygen concentrator includes a first product port, a second product port, an accumulator port, an output port, and a flow path. The flow path operatively coupling each of the first product port, the second product port, the accumulator port, and the output port to one another. The product manifold includes a plurality of control ports. Each of the control ports fluidly coupling the flow path. The product manifold includes a first orifice disposed in a first portion of the flow path; a second orifice disposed in a second portion of the flow path; and a third orifice disposed in a third portion of the flow path. Each of the first orifice, the second orifice, and the third orifice being formed by an electrical forming process and having a thickness of between about 0.0025 inches and about 0.004 inches.

Systems and methods for hypoxia delivery are provided. An apparatus for providing intermittent normoxia and hypoxia intervals includes a breathing component, a normoxia fluid source, a hypoxia fluid source, a valve, and a control system. The valve is configured to disrupt flow from at least one of the normoxia fluid source and the hypoxia fluid source and the control system is configured to cause the at least one valve to switch between delivery of fluid from the normoxia fluid source and the hypoxia fluid source while maintaining positive pressure at the breathing component.

A respiratory device can include an oxygen generator and a ventilator. The oxygen generator can include a first inlet to ambient air, a vacuum or pressure swing oxygen generating system in fluid communication with the first inlet, a first fluid pathway, and a first outlet. The ventilator can include a second inlet to ambient air and a blower in fluid communication with the second inlet to draw ambient air. The ventilator can include a third inlet in fluid communication with the first fluid pathway upstream of the first outlet. The blower can also be in fluid communication with the second inlet to draw at least some of the extracted oxygen. The ventilator can also include a second outlet in fluid communication with the blower to dispense a mixture of the ambient air and the extracted oxygen to the user.

A method of controlling a ventilation system includes displaying, on a display screen of a ventilation system, a first bar including a plurality of parameter segments. Each parameter segment indicates a level of a ventilation setting. The method further includes displaying, on the display screen, a second bar including a plurality of time segments. Each time segment indicates a time duration of a corresponding parameter segment of the first bar. As time passes, the display of the second bar is altered based on an amount of time passing. Upon a time duration of a time segment expiring, the ventilation setting is altered by the ventilation system to a level corresponding to a subsequent parameter segment. The display of the first bar is altered to highlight the subsequent parameter setting.

The invention provides an insufflation apparatus having a housing and a gas generator arranged to be, at least partially, mounted to the housing. The housing includes a gas outlet for delivering gas to a patient and a gas storage chamber arranged to store gas and deliver it to the gas outlet. The gas generator includes a cartridge mount on the housing adapted to receive a gas generating cartridge, the gas generating cartridge containing gas generating material that generates gas that is delivered to the gas storage chamber. The invention also provides alternative insufflation apparatus, a gas cartridge and a method of generating insufflation gas.
