1. An oxygen inhalation therapy system comprising:
a storage unit that receives and stores, from an oxygen supply device which controls flow rates of an oxygen gas to a user, data, for an elapsed time, of at least one of a blood oxygen level of the user and a carbon dioxide partial pressure in arterial blood (PaCO2) level of the user,
an arithmetic logical unit that calculates, from the data, proportions of durations, respective to ones of the flow rates, during which the at least one of the blood oxygen level of the user and the PaCO2 level of the user is in a prescribed range, and
a display unit that displays the proportions of the durations calculated by the arithmetic logical unit, and
wherein the oxygen inhalation therapy system controls the oxygen supply device to supply the oxygen gas to the user based on the flow rates and the proportions.
