Design and Development of Non-Invasive Prototype to Measure Pulse Rate, Blood Glucose and Oxygen Saturation Level in Arterial Blood

The article is dedicated to propose a system which can measure heart rate, blood glucose and oxygen saturation ratio non-invasively with maximum possible accuracy. The design is easy to use, real time and pain free. Preliminary results are acquired on a prototype amplification and filter circuitry, a sensor consisting of two LEDs red (660 nm) and near infra-red (940 nm) as transmission spectrums and an Arduino controller board. Fingertip photoplethysmographic (PPG) signal analysis is done. Furthermore, results have been compared to commercially available pulse oximeter and measurement accuracy of + 3% for pulse rate and + 1% for oxygen saturation is observed. In non-invasive glucose measurement, accuracy plays a vital role. Hence, a 3 day clinical trial is conducted in a hospital for various diabetic and non-diabetic test specimens of different ages. Total 132 specimens were analyzed during the trial period and results are compared with the Beckman coulter AU-480 chemistry analyzer present in the pathology laboratory of the hospital. Clarke Error Grid (CEG) analysis depicts 94.70% of the readings (of all 3 days) fall in the clinically accepted zone A. The Absolute Relative Differences (ARDs) yield mean and median error values of 9.51% and 8.05%, respectively.
