Currently, the reflected-light fingertip blood oxygen meter has been used for medical purposes to diagnose the initial physical condition of patients due to the advantages of this equipment designed able to measure the amount of oxygen in the blood at other locations of the patient's body aside from finger positions such as the forehead, chest, wrists, etc. But a user still found the equipment limitations in measurement accuracy at these body positions compared with the measurement at the finger. This work proposes to develop a low cost newly designed reflected-light blood oxygen meter system to improve efficiency and accuracy of this equipment type when using at another position of the body and evaluate the system performance with comparison to commercial transmissive pulse oximetry. The newly designed system evaluated result by using student's t-test analysis observed prob > |t| greater than 0.05% at the 95% confidence intervals and gauge repeatability and reproducibility is 4.31% measurement variations to ensure that the newly designed system performance is comparable with a commercial pulse oximetry system and capable to accept in clinical condition.
