1. A system for providing ventilation to an individual, the system comprising:
a ventilator;
an oxygen concentrator; and
a patient circuit, the patient circuit comprising:
a jet pump housing defining at least one entrainment port in fluid communication with ambient air;
a low-pressure outlet port configured to output gas from the oxygen concentrator into the jet pump housing;
a jet nozzle cooperatively engaged to the jet pump housing, the jet nozzle defining a high-pressure jet nozzle outlet port configured to output gas from the ventilator into the jet pump housing, the high-pressure jet nozzle outlet port being disposed forward from the low-pressure outlet port, at least the high-pressure jet nozzle outlet port being operative to facilitate air entrainment through the entrainment port and mixing of the entrained air with gas concurrently introduced into the jet pump housing from the high-pressure jet nozzle outlet port and the low-pressure outlet port; and
at least one sensing tube extending to a position distal to the high-pressure jet nozzle outlet port and the low-pressure outlet port.
