A multi-channel pulse oximeter
system is proposed. The
system includes a measurement part for measuring PPG signals in a
light transmission method in six places on a
human body, including both earlobes, both fingers, and both feet, an analysis part for comparatively analyzing the six PPG signals measured by the measurement part, and a result provision part for providing analysis results of the analysis part, wherein the measurement part is configured to include first and second measurement parts respectively mounted on both of the earlobes of the
human body, third and fourth measurement parts respectively mounted on a distal end of any one of
left fingers and a distal end of any one of right fingers of the
human body, and fifth and sixth measurement parts respectively mounted on a left
toe and a right
toe of the human body, the first to sixth measurement parts measuring the PPG signals.
