Connection of a spontaneous delivery device to a concentrator

One or more non-transitory computer-readable storage media including instructions that, when executed by one or more processors, cause the one or more processors to perform the steps of:

• measuring a product gas within an oxygen concentrator over time to produce a product gas measurement waveform;
• determining that an output of the oxygen concentrator is fluidly connected to a ventilator by detecting one or more constant pressure intervals and one or more pressure drop intervals within the product gas measurement waveform;
• in response to determining that the oxygen concentrator is fluidly connected to the ventilator, determining that the output of the oxygen concentrator does not meet a supply gas requirement of the ventilator based on the product gas measurement waveform;
• and
• in response to determining that the output of the oxygen concentrator does not meet the supply gas requirement, adjusting a control output in the oxygen concentrator to modify operation of the oxygen concentrator.

A system, comprising:

• a ventilator;
• an oxygen concentrator with an outlet fluidly coupled to an inlet of the ventilator;
• and
• a controller configured to:
• receive a measurement of a product gas within the oxygen concentrator over time to produce a product gas measurement waveform;
• determine that an output of the oxygen concentrator is fluidly connected to the ventilator by detecting one or more constant pressure intervals and one or more pressure drop intervals within the product gas measurement waveform;
• in response to determining that the oxygen concentrator is fluidly connected to the ventilator, determine that the output of the oxygen concentrator does not meet a supply gas requirement of the ventilator based on the product gas measurement waveform;
• and
• in response to determining that the output of the oxygen concentrator does not meet the supply gas requirement, adjust a control output in the oxygen concentrator to modify operation of the oxygen concentrator.
