An integrated oxygen supply device that is configured to generate oxygen continuously and release the oxygen non-continuously is provided. In some embodiments, the oxygen generated by the integrated oxygen supply device is stored in a porous material with the integrated oxygen supply device. The delivery of the oxygen produced by integrated oxygen supply device to a patient, in those embodiments, is controlled. In some embodiments, the control of the delivering oxygen is according one or more breathing patterns. The breathing pattern(s) may or may not be a current breathing pattern of the patient. For example, in one embodiment, the breathing pattern is a predetermined breathing pattern with a specified inspiration period followed by a specified expiration period.
