1. A method of measuring blood circulation velocity by controlling a person'"'"'s breath, comprising the steps of:

  • keeping the person in a first breathing status with a blood oxygen saturation analytical instrument;

    setting an initial time point and starting to record a blood oxygen saturation value per predict time interval;

    requesting the person to change into a second breathing status at a first time point;

    requesting the person to change into a third breathing status at a second time point;

    stopping recording the blood oxygen saturation value at a terminal time point;

    setting a reference time point according to the blood oxygen saturation value which has a variation according to the records; and

    obtaining the person'"'"'s blood circulation velocity, which is proportional to a reciprocal of a difference of the reference time point and the first time point.
