Claim 14:
15. A system comprising:
a bottle head assembly configured to be coupled to a container, the bottle head assembly configured to seal the container, to pressurize the container, and to depressurize the container, the bottle head assembly comprising:
a servicing port configured to allow flow of oxygen gas from an external source into an interior of the container; and
a pressure transducer configured to measure an internal pressure of the container comprising the oxygen gas; and

a pressure measurement and leak test tool configured to:
couple to the bottle head assembly;
perform a leak test of the container by:
receiving a first electrical signal from the pressure transducer, the first electrical signal corresponding to a first pressure measurement of the container;
after a predetermined amount of time, receiving a second electrical signal from the pressure transducer, the second electrical signal corresponding to a second pressure measurement of the container;
determining a rate of change between the received first electrical signal and the received second electrical signal; and
displaying a leak test result based on the determined rate of change; and

simultaneously display information associated with the first pressure measurement, the second pressure measurement, and the leak test on a display of the pressure measurement and leak test tool.
