System and method for point-of-delivery patient oxygen supply monitoring

An apparatus, comprising:

• a housing having at least one port defined therein, a first port from the at least one port configured to mechanically couple to a dual lumen gas supply tube of an oxygen gas delivery system;
• a microcontroller disposed within the housing;
• a first sensor operably coupled to the microcontroller and disposed within the housing, the first sensor aligned with a first lumen of the dual lumen gas supply tube when the at least one port is mechanically coupled to the dual lumen gas supply tube;
• a second sensor different from the first sensor and operably coupled to the microcontroller and disposed within the housing, the second sensor aligned with a second lumen of the dual lumen gas supply tube and not the first lumen when the at least one port is mechanically coupled to the dual lumen gas supply tube;
• and
• a power supply disposed within the housing and configured to supply power, during operation, to the microcontroller, the first sensor, and the second sensor,
• the microcontroller configured to perform monitoring of the oxygen gas delivery system, the monitoring including receiving data generated by at least one of the first sensor or the second sensor when the at least one port is mechanically coupled to the dual lumen gas supply tube and when oxygen is flowing through the at least one port.
