Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment.

A bi-level positive airway pressure device includes a housing that has a patient port for connecting to an airway of a patient. There is a device (e.g., a nozzle) for generating a positive airway pressure that is directed through a conduit towards the patient port. An exhalation detector includes a nozzle emitting a jet of a gas directed across the conduit and directed at a receptor channel when exhalation gases flow from the patient port, thereby an increase a gas pressure is present at the receptor channel when the exhalation gases flow from the patient port. The exhalation detector converts the increase in the gas pressure into a movement of an occluding member such that when the exhalation gases flow from the patient port, the occluding member moves to block the means for generating the positive airway pressure.

A system for providing continuous positive air pressure therapy is provided. The system includes a flow generator, a sensor, and a computing device. The computing device is configured to control operation of the flow generator based on sensor data. The computing device is further configured to display, on a display device, one or more questions relating to demographic and/or subjective feedback; responsive to displaying the one or more questions, receive one or more inputs indicating answers to the one or more questions; transmit the answers to a remote processing system; receive, from the remote processing system, settings determined based on the transmitted answers; and adjust control settings of the system based on the received settings.

A medical double configurational and multiple ports mask preferably including a multifunctional plug with or without a nebulizer oxygen delivery adaptor (“NODA”) attachment. The mask fits over the mouth and the nose and preferably contains at least two possible nose/face configurational solutions. The mask can be secured over the head with a stretchable or non-stretchable material. The position of the preferred triple ports of the double configurational mask provides improved structural construction reflecting different patient's nose/face features and allows for different types of procedures to be performed at the same time regardless of the patient's head/neck position. The multifunctional plug can be used for a variety of applications. The mask can be used with existing standardized disposable respiratory care equipment, including a simplified improved nebulizer oxygen adaptor (“SINODA”) and/or multifunctional use nebulizer oxygen delivery adaptor (“MUNODA”) attachment.

In one embodiment, the present invention provides a system to deliver at least one therapeutic gas to a spontaneously breathing patient, wherein the rate of delivery of the at least one therapeutic gas exceeds the patient's inspiratory flow rate, and the amount of the at least one therapeutic gas that is wasted is minimized or eliminated.

A patient interface may have a frame and a seal-forming structure. The frame may at least partially form a plenum chamber pressurisable to a therapeutic pressure. The seal-forming structure may be constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways, said seal-forming structure having a hole therein such that the flow of air at said therapeutic pressure is delivered to at least an entrance to the patient's nares, the seal-forming structure constructed and arranged to maintain said therapeutic pressure in the plenum chamber throughout the patient's respiratory cycle in use. The seal-forming structure may comprise a textile seal member adapted to sealingly engage the patient's face in use.

A system for irrigating and cleaning nasal cavities is provided. In some embodiments, the system includes a stand configured to hold an aqueous solution container. A primary incoming tube leading to a face mask device configured to be worn by a user. In one embodiment, the solution is gravity fed directed through the primary incoming tube into at least one port of the face mask device. A drain line leads from the face mask device to a collection container.

Topical applications that provide a nitric oxide therapy to a surface are provided. Systems for providing a topical nitric oxide therapy can comprise a nitrite medium in a first container, the nitrite medium comprising about 3% of a nitrite component by weight. The system comprises an acidic medium in a second container, the acidic medium comprising about 9% by weight of one or more acidic reactants. The nitrite medium and the acidic medium are configured to be combined to form a nitric oxide topical medium producing nitric oxide suitable for topical application and suitable for administering nitric oxide therapy wherein a therapeutically effective amount of the nitric oxide topical medium is applied to a treatment surface suitable for receiving nitric oxide therapy, whereby the application of the therapeutically effective amount is adapted to deliver a dose of nitric oxide at the treatment surface of a patient.

A system for delivering oxygen comprises an oxygen source; a ventilator operatively connected to the oxygen source to receive a supply of oxygen therefrom; a valve having a) an open position in which the ventilator receives the supply of oxygen from the oxygen source and b) a closed position in which the ventilator is not in fluid communication with the oxygen source; a sensor configured to measure breath flow information for the patient; and a computer system to: determine a volume of gas delivered to the patient during a breath cycle of the patient and an inspiratory volume of gas delivered to the patient during an inspiration phase of the breath cycle by using the breath flow information; and provide input to the valve based on the determined volumes, the provided input causing a movement of the valve between the open and the closed positions.

Provided is a system for adsorbing a gaseous component comprising nitrogen from a pressurized flow of air containing the gaseous component. The system comprises a first adsorption bed, and a second adsorption bed. Each of the adsorption beds are suitable for selectively adsorbing the gaseous component from the flow of air to produce a product gas having a higher oxygen concentration than that of the air. The system includes an adjustable feed gas supply which alternately supplies the first adsorption bed and the second adsorption bed with the air. The first adsorption bed is supplied with air during a first half cycle of operation of the system, and the second adsorption bed is then supplied with air during a second half cycle of operation of the system. The feed gas supply enables adjustment of at least one parameter relating to the amount or respective amounts of air being supplied to the first adsorption bed in the first half cycle and/or to the second adsorption bed in the second half cycle. A connection and valve assembly is provided between the first and second adsorption beds. The connection and valve assembly diverts a portion of the product gas, produced from the respective absorption bed being supplied with the flow of air during the respective half cycle, to the other adsorption bed. This causes previously adsorbed gaseous component to be released from latter. The released gaseous component then escapes from the system, e.g. to the atmosphere, via a vent. A sensor system determines a measure of the flow rate of waste gas, including the released gaseous component, escaping from the system via the vent. The at least one parameter can be adjusted based on the measure in order to tune the performance of the system. Further provided is a method for operating the system.
