This article explores the key differences between SpO₂, SaO₂, and PaO₂, which are essential for assessing oxygen levels in the blood. It highlights the use of SpO₂ sensors for quick, non-invasive assessments in emergency settings and compares SpO₂ vs SaO₂ and SaO₂ vs PaO₂ for more precise insights in critically ill patients. The PaO₂-FIO₂ ratio is explained as a critical tool for evaluating ARDS severity.

The article also covers the Oxygen-Hemoglobin Dissociation Curve and its role in oxygen delivery, alongside the limitations of each measurement method. By understanding these differences, healthcare professionals can make informed decisions to improve patient care, especially in ICU settings and for managing chronic respiratory conditions. Key terms such as SpO₂ vs PaO₂, SaO₂ meaning, and SpO₂ vs PaO₂ are addressed for a comprehensive understanding.
