1. A ventilation system comprising:
a ventilator; and
a nasal interface in fluid communication with the ventilator, the nasal interface comprising:
one or more tubular bodies collectively defining a pair of gas flow paths that terminate respectively in a pair of distal gas flow openings;
one or more nozzles for delivering gas from the ventilator into the one or more tubular bodies;
a pair of nasal cushions attachable respectively to the pair of distal gas flow openings and in fluid communication with the one or more gas flow paths; and
a pair of pressure sensing lumens each of which terminates in a pressure sensing port in a respective one of the gas flow paths at a location nearer to the respective gas flow opening than to the one or more nozzles.
