Abstract/Summary
In modern medical practice, the blood oxygen level is considered one of the important vital signs of the body (Renesas, 2011). A pulse oximeter is a non-invasive medical device capable of detecting oxygen saturation of arterial blood and gives information about the cardiorespiratory function of a patient. The issue addressed by the study is not only the price of commercial pulse oximeters but also the reliability, maintenance and most importantly, the accessibility of the pulse oximeter. The hardware design of the prototype is the custom built oximeter which is interfaced correctly to the 3.5 mm port of the Android phone. The software design of the prototype is the program that will simultaneously get signals , calculate the oxygen saturation using an algorithm and display the values on the screen of the phone. The researchers were able to successfully test the prototype oximeter with the finger pulse oximeter on at least 30 subjects. The results show that the Mobile Oximeter device does deviate from the readings but on average, by calculation of the percent error and percent accuracy, it was found that the percent error does not exceed 2% on average, The researchers have concluded that the study was a success and that it is possible to create an android-based medical device such as an oximeter that can measure oxygen saturation in the blood with accuracy with the use of locally available electronic parts which costs less than a commercial finger pulse oximeter.
