Abstract
Objective: Evaluate the relationship between pulse oximetry saturation with arterial blood gas saturation on clinical ground.
Methods: Prospective cross-sectional study. 162 adult patients, aged from 19 to 97, admitted to intensive care unit from 10/2010 to 9/2011. All patients included in the study were recorded Spo2 three times (15 minutes before, 0 and 15 minutes after taking blood for blood gas analysis. A standard form recorded all demographic and clinical, paraclinical features: age, gender, diagnosis, pulse, blood pressure, shock status, hemoglobin.etc... Calculating the correlation r between SpO2 (pulse oximeter) and SaO2, (blood gase) according to other diseases and other status such as shock, anemia... Using method of Bland and Altman to determine the agreement between Spo, and SaO2
Results: The correlation (R) between SpO2, and SaO2, for all patients was 0,25 (p = 0001), for patients without shock was 0,31 (p=0,000); for ventilated patients was 0.74 (p=0,000); for patients without anemia (HGB≥ 10 mg/dL) was 0,318 (p=0.000).
Conclusion: There is a good correlation and agreement between SpO2, and SaO2, for patients without shock and without anemia.
