The systems can be well5 suited for use in providing CPAP therapy for a neonate or infant patient, with the ability to also provide resuscitation therapy at a peak inspiratory pressure (PIP) as needed or desired without switching to another system or switching the patient interface. The system can include an expiratory pressure device capable of regulating a positive end expiration pressure (PEEP) of the system, which preferably can also induce pressure 10 oscillations relative to a mean PEEP. -24-WO 2013/154439 PCT/NZ2013/000062 1/5 /0 222 20 FIG. ]A 26 870 62 82 322 64 FIG.
