A system for detecting manual ventilation and selectively delivering a high flow of oxygen. The system comprises a source of compressed oxygen coupled to a first lumen of a nasal cannula, with an oxygen flow control valve coupled to a processor to control the flow of oxygen to the nasal cannula. A second lumen of the nasal cannula is in connection with a pressure sensor and the pressure sensor in connection with the processor. The processor may receive the pressure values and be programmed to determine when manual ventilation has occurred, and send a signal to the oxygen flow control valve to send a high flow of oxygen in response to manual ventilation.

Sensing airflow and delivering therapeutic gas to a patient. At least one example embodiment is a method including: sensing, by a delivery device, that multiple breathing orifices are open to flow; and during a plurality of subsequent inhalations in which multiple breathing orifices are open to flow; and delivering, by the delivery device, a bolus of therapeutic gas to only one breathing orifice during each inhalation, and alternating delivery location in subsequent inhalations. The example delivering may further comprise: supplying therapeutic gas only from an accumulator during a first portion each inhalation; dispensing therapeutic gas from the accumulator and from a pressure regulator during a second portion of each inhalation, the second portion immediately subsequent to the first portion.

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.

Methods and apparatus provide controlled operations in an oxygen concentrator (100) such as by adjusting valve opening time to regulate amount of oxygen enriched air released to a user. The apparatus may generate, with a sensor configured to sense pressure at a location associated with accumulation of enriched air produced by the concentrator, a signal representing measured pressure of the accumulated enriched air. The apparatus may generate, with a sensor, a signal indicative of respiration of a user of the concentrator. The apparatus may include a controller configured to receive the measured pressure and respiration signals. The controller may control, responsive to the respiration indication and according to a target duration, actuation of a valve adapted to release a bolus of accumulated oxygen enriched air. The controller may dynamically determine the target duration during the release of the bolus according to a function of a value of the measured pressure.
