Method and System of Measuring Blood Circulation Velocity
First Claim
1. A method of measuring blood circulation velocity comprising the steps of:
- keeping a person measured by a blood oxygen saturation analytical instrument and served by a ventilator;
setting an initial time point, providing a first gas to the person via the ventilator, and starting to record a blood oxygen saturation value per predict time interval;
providing a second gas to the person at a first time point;
providing a third gas to the person 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 the reciprocal of the difference of the reference time point and the first time point.
