1. A pressure-assisted breathing system comprising:
- an air flow generator;
a circuit connecting the air flow generator to a patient'"'"'s respiratory system; and
an aerosol generator for emitting aerosol particles into the circuit;
wherein the circuit defines a path from the point at which the aerosol generator emits aerosol particles into the circuit to the point at which the aerosol particles enter the patient'"'"'s respiratory system, the path having a change in angle of no greater than 15°

17. A patient interface device for the delivery of aerosol particles to a patient comprising:
-
a tubular inlet section having a longitudinal lumen; a pair of nasal cannula; and a tubular forked section connecting the inlet section to the nasal cannula; wherein the longitudinal lumen is in fluid communication with lumens in each prong of the forked section so as to conduct the aerosol particles along two paths from the point of entry of the aerosol particles into the patient interface device to the point at which the aerosol particles enter the patient'"'"'s respiratory system, each path having a change of angle no greater than 15°

26. A method of treating infant respiratory distress syndrome comprising the steps of:
-
(a) attaching the infant to a NCPAP system comprising; (i) a pressure-generating circuit; (ii) a respiratory circuit that conducts a pressurized gas flow from the pressure-generating circuit to a nasal cannula patient interface device, and (iii) a vibrating aperture-type nebulizer in fluid communication with the respiratory circuit so as to introduce aerosol particles of surfactant medication into the pressurized gas flow in the respiratory circuit;
wherein the nasal cannula interface device defines a path for the aerosol particles from the point of entry of the aerosol particles into the nasal cannula interface device to the point of entry of the aerosol particles into the infant'"'"'s respiratory system, said path having a changed in angle no greater than 15°
; and(b) administering the aerosol particles of surfactant medicament to the infant via the nasal cannula interface device.
