Abstract
A nasal patient interface arrangement is for transporting breathing gas from a pressurized gas supply to a patient. The arrangement provides a first bidirectional gas passage in contact with ambient air and receives nasally expired air. The arrangement includes an inspiratory air conduit connecting to a pneumatic unit. The arrangement also includes a nose adapter for bidirectional gas transport. The nose adapter is connected to a nose of the patient. The arrangement further includes a valve arrangement controlling the passage of gas through the first bidirectional gas passage. The arrangement provides a second bidirectional gas passage which is connected to the inspiratory air conduct, the nose adapter, and the first gas passage. The valve arrangement is substantially enclosed in the first bidirectional gas passage.
