Oxygen Flow Meter Automation Design Based on SpO2 Levels
Parameter SPO2
Abstract
Oxygen therapy, also known as supplemental oxygen, is a medical intervention aimed at ensuring adequate oxygen levels within the body. At certain levels, oxygen deficiency or excess in the blood can pose risks to a patient’s health if left untreated. When administering oxygen therapy, it is crucial to adhere to the appropriate dosage while continuously monitoring the patient’s oxygen saturation levels. The objective of this research is to design a device capable of monitoring blood oxygen saturation in patients. This study serves as a reference for oxygen therapy (oxygenation) in patient care. To enhance practicality and efficiency, the device is designed for real-time monitoring. The system utilizes a DS-100A finger sensor to capture light absorbed by hemoglobin, which is then processed to provide SpO2 (oxygen saturation) values. The module yields SpO2 readings as a percentage. Testing with standard measurement tools on respondents resulted in a maximum error percentage of 1.7%. The findings from this research can be implemented in automatic oxygen regulators based on patient SpO2 levels, thereby improving the efficiency of monitoring oxygen therapy dosages
