Abstract: Ventilation masks are described herein. A ventilation mask includes a mask body and a gas manifold. The mask body defines a patient cavity and further includes a patient opening in fluid communication with the patient cavity; and at least one vent opening formed through the mask body, the at least one vent opening in fluid communication with the patient cavity, wherein the at least one vent opening is disposed generally opposite to the patient opening. The gas manifold is coupled to the mask body. The gas manifold can define a gas channel. The gas manifold can include a plurality of vectored gas ports in fluid communication with the gas channel, wherein the plurality of vectored gas ports are configured to create a curtain effect gas flow within the patient cavity to form a gas curtain within the patient cavity and adjacent to the at least one vent opening.

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

Abstract: A respiration sensor fluid delivery device is provided. The device includes first and second nasal exhalation flow passages that extend through the device, wherein the first and second nasal exhalation flow passages can be aligned in parallel to one another with respect to a nasal respiratory flow direction. A housing of the respiration sensor fluid delivery device fluidly couples with one of a nasal cannula assembly and a respiratory mask assembly. The device provides for respiration monitoring of a subject via a sensor and fluid delivery, such as oxygen, to the subject. Methods of using a respiration sensor fluid delivery device and fluid delivery devices are also provided.

Abstract: Airway adapters, suction catheter systems, and methods of using the same are described herein. An exemplary airway adapter assembly may comprise a connector body portion having a first end and a second end, an elongate cavity having an axial center can be defined between the first and the second end, and a valve can be coupled to the second end of the connector body. The exemplary airway adapter assembly may also comprise a ventilation base member comprising a tubular portion coupled to the second end of the connector body portion and ventilator port. The ventilator port may comprises a conduit having a first conduit end and a second conduit end, and the first conduit end may be coupled to the tubular portion through an articulable connection. An exemplary closed suction catheter system may comprise a suction control valve assembly and a closed suction catheter sheath.
