PROBLEM TO BE SOLVED: To provide an oxygen condenser which is capable of supplying the gas with oxygen condensed of a high flow rate with the device of a small size without sense of incongruity and a controller as well as a recording medium for the same. SOLUTION: In a step 100, whether the setting of the flow rate of a flow rate setter 45 is below 3L per minute of a continuous base flow rate or not is decided. In a step 110, the set flow rate is as low as below 3L per minute and therefore this case is decided not to carry out breathing synchronization (to carry out continuous supply) and the gas with the oxygen condensed is continuously supplied to meet the set flow rate. In a step 120, the set flow rate is a high flow rate to exceed 3L per minute and therefore this case is decided to carry out the breathing synchronization and an orifice is set at an opening degree at which the supply of 5L per minute is possible. In a step 140, the control to open and close a solenoid valve 47 is carried out for the purpose of the breathing synchronization. As a result, the gas with the oxygen condensed is supplied at the high rate (5L per minute) in the inspiration period of respiration cycles and the gas with the oxygen condensed is supplied at the low rate (2L per minute) through a bypass flow passage 50 in the expiration period. |
