1. A removable gas sensor module for a therapeutic gas delivery device, the gas sensor module comprising:
a sample chamber operable to receive a sample gas from the therapeutic gas delivery device; and
a gas detection unit comprising a plurality of sensors operable to measure at least one property of the sample gas, wherein the plurality of sensors include two or more of a gas detection sensor, a humidity sensor, a temperature sensor, or a combination thereof,
wherein the gas sensor module is self-contained within the therapeutic gas delivery device and swappable with another gas sensor module,
wherein the plurality of sensors is pre-calibrated and shelf stable in a non-installed configuration for at least 1 month,
wherein the plurality of sensors includes an NO sensor and an NO2 sensor,
wherein the plurality of sensors is operable to receive an electrical potential from a voltage source when the gas sensor module is not installed in the therapeutic gas delivery device, and
wherein the electrical potential maintains the pre-calibration of the plurality of sensors when the gas sensor module is not installed in the therapeutic gas delivery device.
