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.
Claims10
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.
