(57) Abstract: Provided is a portable oxygen concentrating system configured to be easily carried by a user, and an oxygen supply method using the system. SOLUTION: The portable oxygen concentrating system according to the present invention is driven by an energy source and the energy source, An air separation device configured to convert ambient air to enriched oxygen gas for a user, and at least one sensor configured to sense one or more conditions representative of the oxygen gas required by the user And the at least one Controlling the air separation device to supply an amount of oxygen equal to the oxygen gas required by the user based at least in part on one or more conditions sensed by the one or more sensors. A control unit interconnected with the at least one sensor; Consists of |
