[Study of Blood Oxygen Measuring Method Based on Multiple Regression Analysis].

Area of Science:

• Biomedical Engineering
• Medical Diagnostics

Background:

• Traditional blood oxygen measurement relies on the amended Lambert-Beer Law.
• This method suffers from slow results due to division operations and reduced accuracy from ratio errors.

Purpose of the Study:

• To develop a more accurate and efficient method for blood oxygen percentage measurement.
• To address the limitations of the traditional Lambert-Beer Law approach.

Main Methods:

• Utilized multiple regression analysis for blood oxygen evaluation.
• Compared the performance of multiple regression analysis against the traditional ratio method.

Main Results:

• The multiple regression analysis method demonstrated a clear advantage over the traditional ratio method.
• The new method showed improved accuracy in blood oxygen percentage measurement.

Conclusions:

• Multiple regression analysis offers a superior approach for blood oxygen measurement.
• The proposed method is easier to implement in hardware compared to traditional techniques.
