Claims21
1-60. (canceled)
A patient interface comprising:
- a pair of nasal interfacing components configured to deliver inspiratory gases to a user and configured to receive expiratory gases from the user, the pair of nasal interfacing components comprising a first nasal interfacing component and a second nasal interfacing component;
- and
- a bridge valve operable to selectively control passage of gases through the pair of nasal interfacing components,
- wherein in a first mode, the bridge valve is operable to provide the inspiratory gases to the user solely through one of the first nasal interfacing component or the second nasal interfacing component and to receive the expiratory gases from the user solely through the other of the first nasal interfacing component or the second nasal interfacing component,
- wherein in a second mode, the bridge valve is operable to allow the inspiratory gases to be delivered to both the first nasal interfacing component and the second nasal interfacing component.

A respiratory therapy system comprising:
- a patient interface comprising:
- a pair of nasal interfacing components configured to deliver inspiratory gases to a user and configured to receive expiratory gases from the user, the pair of nasal interfacing components comprising a first nasal interfacing component and a second nasal interfacing component;
- and
- a bridge valve operable to selectively control passage of gases through the pair of nasal interfacing components,
- wherein in a first mode, the bridge valve is operable to provide the inspiratory gases to the user solely through one of the first nasal interfacing component or the second nasal interfacing component and to receive expiratory gases from the user solely through the other of the first nasal interfacing component or the second nasal interfacing component,
- wherein in a second mode, the bridge valve is operable to allow inspiratory gases to be delivered to both of the pair of nasal interfacing components.
