Claim 0:
1. A system for providing oxygen and mechanical ventilation therapy to an ambulatory patient, the system comprising:
a nasal interface apparatus comprising:
a pair of nasal pillows, each of the pair of nasal pillows configured to be secured at least partially within a nostril of the patient and having a first end and a second end opposite the first end, the second end configured to be positioned farther inside the nostril when the nasal interface apparatus is in use; and
a pair of hub components, each of the pair of hub components arranged at the first end of one of the pair of nasal pillows and configured to receive oxygen-enriched gas from one of a pair of tubes of the system, each of the pair of hub components comprising one or more delivery openings configured to direct the oxygen-enriched gas toward the second end of the one of the pair of nasal pillows; and

a portable oxygen concentrator (POC) comprising:
a compressor configured to receive and compress ambient air, the compressor further configured to output the compressed ambient air;
a gas separation member; and
an outlet connected to said pair of tubes;

wherein:
the POC is configured to guide a first portion of the compressed ambient air to the gas separation member and guide a second portion of the compressed ambient air to bypass the gas separation member and flow to said outlet;
the gas separation member produces an oxygen-enriched gas based on the first portion of the compressed ambient air;
the outlet is configured to guide the oxygen-enriched gas and the second portion of the compressed ambient air to the pair of tubes, the pair of tubes configured to guide the oxygen-enriched gas and the second portion of the compressed ambient air directly to the pair of hub components of the nasal interface apparatus;
the nasal interface apparatus is configured to entrain ambient air in conjunction with the oxygen-enriched gas received from the POC; and
the POC is further configured to provide varying levels of ventilation support and oxygen enrichment to the patient when ambulating by varying an amount of the second portion of the compressed ambient air bypassing the gas separation member.
