Another Geometry Equation using Linear Elastic Glucose Theory to Estimate Average Sensor PPG and Finger PPG based on GH-Method: Math-Physical Medicine, LEGT Part 29 (No. 418)

Abstract

Gerald C Hsu

On 10/14/2020, the author wrote his first research note on his developed linear elastic glucose theory (LEGT). Over the past 5+ months, he has continuously conducted his research on this subject, where he completed his research note on a summary report, No. 415, LEGT Part 26 on 3/15/2021. In the LEGT research note, No. 416, Part 27, he applied simple geometry to derive a set of equations in estimating the average LEGT sensor PPG and LEGT finger PPG values known as Equation A, which were based on values of P1, P2, and P3. In the current research note, No. 418, Part 28, he derived another set of equations for the same two PPG values known as Equation B, which were based on values of Weight or FPG, carbs/sugar intake amount, and post-meal walking k-steps. In summary, similar to the Young’s modulus of engineering materials, the GH.p-Modulus for diet is the most important GH-Modulus of biomedicine applications. This is related to and dependent on the patient’s overall metabolic conditions, age, lifestyle, health, medical diseases, types of food, amount of carbs/sugar intake, and to some degree the chosen time-window for certain analyses. Nevertheless, its linear and elastic behaviors and general glucose characteristics are quite comparable to the Young’s modulus of stress and strain in theory of elasticity of engineering. All of the author’s collected glucose data to date present their behaviors within the defined “elastic” region. Therefore, his developed LEGT would be useful for other type 2 diabetes (T2D) patients to control their diabetes conditions.
