    Abstract: A respiratory access assembly may include a manifold having a first mating surface defining a first port opening. The respiratory access assembly may include a rotatable adapter having a second mating surface defining a second port opening and a seal assembly disposed between the manifold and the rotatable adapter that includes a first seal ring, a second seal ring, and an outer seal ring disposed proximate an outer perimeter of at least one of the manifold or the rotatable adapter. The rotatable adapter may be rotatable relative to the manifold between an open configuration and a closed configuration. The seal assembly may include a connection portion connected between the first seal ring and the second seal ring. The connection portion may form a seal between the first mating surface and the second mating surface between the first seal ring and the second seal ring.

    Abstract: A method of, or system for, ventilating lungs in breathing and non-breathing patients—including applications for anesthesia—may comprise maintaining an inspiratory flow rate at an inspiratory setpoint at a low flow setting. Lung pressure in a patient may be regulated between a high pressure setpoint and a low pressure setpoint with periodic expiratory flows and continuous inspiratory flow. An expiratory control valve may be adjusted to an open position when a lung pressure is at or above a high pressure setpoint. An expiratory control valve may be adjusted to a closed position when a lung pressure is at or below a low pressure setpoint. Concurrent venting outflow and CO2 offloading through flow within the lungs may be facilitated by providing an intermittent expiratory flow to the patient while providing the continuous inspiratory flow.
