A respiratory system includes a first patient interface for delivery of a flow of gases to a patient, a second patient interface for delivery of a second flow of gases to the patient, and a device that switches the system between a first respiratory mode and a second respiratory mode. In the first respiratory mode, the flow of gases are delivered to an outlet of the first patient interface when the second patient interface is absent from the patient. In the second respiratory mode the device reduces or stops delivery of the first flow of gases to the outlet of the first patient interface when the second patient interface is located together with the first patient interface upon the patient.

User interface and system for supplying gases to an airway

The invention relates to a respiratory system comprising a first patient interface for delivery of a first flow of gases to a patient, a second patient interface for delivery of a second flow of gases to the patient, and a device and/or sensing arrangement that is configure to facilitate a switching of the system between a first respiratory mode where the device allowing delivery of the first flow of gases to an outlet of the first patient interface when the second patient interface is absent from the patient, and a second respiratory mode where the device reducing or stopping delivery of the first flow of gases to the outlet of the first patient interface when the second patient interface is located together with the first patient interface upon the patient.

Several methods of supporting respiratory function of a patient before, during and/or after a medical procedure are disclosed. In certain arrangements, supporting respiratory function while a patient is under general anaesthesia can include providing a high gas flow that is greater than 15 L/min while the patient is under general anaesthesia. In certain arrangements, a method of providing ventilation while a patient is under general anaesthesia involves providing only a gas flow delivered through a nasal interface that is greater than 15 L/min while the patient is under general anaesthesia.
