Abstract

This research includes a theoretical study of the effect of the variables of the oxygen value SpO2 associated with the ratio of R ratios, based on the experimental results that we obtained from some volunteers, depending on the relationship: SpO2 = 110 - 25 R.

Pulse oximetry devices are widely used as a non-invasive method for monitoring blood oxygen saturation and heart rate.

A pulse oximeter shines light at two different wavelengths in vascular tissues and detects changes in transmitted or reflected light energy.

In our research, the direct method of oxygenation was relied upon and the results were compared with the commercial oximeter.

We present a pulse oximetry system based on red and near-infrared (650 and 808 nm) laser diodes for monitoring the oxygen saturation of hemoglobin in arterial blood.

The pulse oximetry system consists of the optical sensor, sensor electronics and processing block. Also, we present the experimental results obtained during the development of the oximetry system along with the modifications in the sensor configuration, as the study showed that when the percentage of SpO2 increases, the value of the constant R decreases.
