Abstract

An oxygen therapy system receives data for an elapsed time such as a flow rate of oxygen gas, and a blood oxygen level or a carbon dioxide partial pressure in arterial blood (PaCO2) level of a user, from an oxygen supply device, calculates a proportion of a duration for each oxygen gas flow rate during which the blood oxygen level or PaCO2 is in a prescribed range from the acquired data in which the oxygen gas flow rate fluctuates with the blood oxygen level or carbon dioxide partial pressure in arterial blood (PaCO2), and displays the calculated data as a histogram or pie graph on a terminal which a healthcare worker such as a physician operates.
