1. A patient interface for a non-invasive ventilation system, the patient interface comprising:
a manifold having a gas delivery tube attachment and a tubular extension configured to impinge with a nostril, the manifold defining a gas flow path therein that terminates at a distal end of the manifold and a pressure sensing lumen that terminates in a pressure sensing port that opens into the gas flow path; and
tubing attachable to the gas delivery tube attachment, the tubing including:
a ventilator gas delivery channel for delivering ventilation gas from a ventilator into the gas flow path of the manifold via a gas delivery nozzle to define a gas flow direction of the gas flow path, the gas flow path being curved such that the gas delivery nozzle is angulated into a wall of the manifold, the pressure sensing port opening into the gas flow path at a position inside the manifold downstream of the gas delivery nozzle in the gas flow direction; and
a pressure sensing channel that communicates with the pressure sensing lumen to place the ventilator in communication with the pressure sensing port, the pressure sensing channel and the ventilator gas delivery channel being within the same tube of the tubing for communication with the manifold via the same gas delivery tube attachment,
wherein the patient interface further comprises an aperture through which ambient air may be entrained by the ventilation gas exiting the gas delivery nozzle, the aperture being at least partially downstream of the gas delivery nozzle.
