PROBLEM TO BE SOLVED: To provide breathing guidance that makes a patient breathe easily.SOLUTION: A breathing guide apparatus monitors a differential signal SD to detect a time point tat which the differential signal SD returns to a value &Dgr;Sof almost zero (time point of the end of breathing out). When the time point tis detected, a loudspeaker outputs audio guide information "breathe in" in response to the detection. Thus the patient can hear a voice "breathe in" almost at the end of breathing out, so the patient can avoid unnaturally continuing to breathe out, ensuring that the patient can transition from breathing out to breathing in smoothly. |
