Ventilator system with multiple inspiratory lumens is provided. The inspiratory lumens are configured so that separate inspiratory lumens provide inspiratory gas mixtures to separate portions of a patient's airways, for instance to separate lungs and/or bronchi. The ventilator system can include one or more expiratory lumens to evacuate expiratory gases from airways. The use of separate inspiratory lumen(s), with expiratory lumen(s), allows for functional separation of structural portions of the lungs, and maintenance of continuous or almost continuous flow through at least part of respiratory cycle via inspiratory and expiratory lumens. This can further reduce dead space and clear suspended therein diseases causative agents with improvement in outcomes, reduce risk of cross-contamination or cross-infection between different parts of airways, for example such as cross-infection from one lung lobe to another lobe or. The ventilator system allows for independent titration of PEEP, pCO.sub.2 and pO.sub.2 with no need for permissive hypercapnia.

Exemplary embodiments are directed to an apparatus for manipulating one or more characteristics of air to be inhaled. The apparatus includes an outer housing including an outer surface, a hollow interior, and at least one opening formed in the outer housing and extending between the outer surface and the hollow interior. The apparatus includes a manipulation enclosure disposed within the hollow interior of the outer housing, the manipulation enclosure capable of receiving therein an air characteristic manipulation component. A substantially continuous channel is formed between the manipulation enclosure and the outer housing.

A humidifier for humidification of air to be delivered to a patient's airways may include a humidification chamber, a reservoir and a water delivery mechanism. The humidification chamber may include a water retention feature such as a wick, a heating element for heating the humidification chamber, and an air flow baffle configured to promote humidification. The humidifier may be further configured to execute one or more algorithms, for example to determine a condition of the humidifier and/or to mitigate any detected faults. In some forms, the humidifier may also comprise algorithms for controlling one or more components of the humidifier.

A nasal ventilation mask having one or more attachment ports located adjacent to and overlying an upper lip of a patient when worn.

An apparatus to maintain an environment over an anterior surface of a patient eye can include an enclosure sized and shaped to be seated about the patient eye to form a cavity within the enclosure. The enclosure can be configured to contain a fluid other than ambient air in contact with the patient eye. The apparatus can include a fluid regulator in communication with the enclosure, where the fluid regulator can be configured to regulate the composition of the fluid contained within the enclosure.

A humidification system has a humidification source and a main gases flow path. The main gases flow path has a low pressure region and a high pressure region. In some embodiments, each of the low pressure region and the high pressure region has an aperture. The pressure difference between the apertures promotes a gases flow between the main gases flow path and the humidification source, and results in humidifying the gases in the main gases flow path.

A respiratory ventilation apparatus configured to deliver a respiratory gas to a patient interface is provided. The apparatus may include a gas pressurization unit configured to generate a pressurized respiratory gas, a gas inlet port configured to introduce the respiratory gas into the respiratory ventilation apparatus, a gas outlet port configured to discharge the pressurized respiratory gas to a respiration tube, a detection module configured to detect the pressure of the pressurized respiratory gas, at least one non-volatile memory configured to store a plurality of parameters and a plurality of programs, and one or more controllers. The one or more controllers may be configured to initiate the respiratory ventilation apparatus upon a boot operation, and/or initiate a program that constantly reads information from the detection module, and controls the pressure of the pressurized respiratory gas using the information read from the detection module and at least one parameter.

A method includes receiving first physiological data associated with a user. The method also includes determining a first emotion score associated with the user based at least in part on the first physiological data. The method also includes modifying one or more settings of a respiratory therapy system responsive to determining that the first emotion score satisfies a predetermined condition.

A nasal cannula interface is provided for a respiratory support system configured to receive a breathable gases flow, the nasal cannula interface comprising: a. an inlet to receive the gases flow; b. at least one nasal prong configured to receive the gases flow from the inlet, and to be received in, and to deliver the gases flow to, a nare of the patient. The nasal cannula interface may comprise one or more structural features that are configured to help manage, avoid and/or reduce generation of aerosols by the patient during breathing and/or whilst breathing gases from a respiratory support apparatus.

A flow of gases in a respiratory therapy system can be conditioned to achieve more consistent output from sensors configured to sense a characteristic of the flow. The flow can be mixed by imparting a tangential, rotary, helical, or swirling motion to the flow of gases. The mixing can occur upstream of the sensors. The flow can be segregated into smaller compartments to reduce turbulence in a region of the sensors.
