Correlation of Pulse Oximetry With Arterial Blood Gas Derived Oxygen Saturation in ICU Patients on Supplemental Oxygen - A Prospective Cross-sectional Study

This was a prospective cross-sectional observational study conducted among 152 patients, admitted to Medical Intensive Care Unit (MICU), who required supplemental oxygen during hospital stay. The ABG analysis was done, and pulse oximeter reading was recorded simultaneously. The goal of the study was to correlate oxygen saturation measured by pulse oximeter (SpO2) with arterial blood gas analysis (SaO2).
