Fig. 3From: Performance of the new SmartCardia wireless, wearable oximeter: a comparison with arterial SaO2 in healthy volunteersBland-Altman curve showing agreement between a: SmartCardia, b: Masimo and c: Nellcor, SpO2 and arterial SpO2. Data is plotted as Hemoximeter data (SaO2) vs. pulse oximeter bias (SpO2 – SaO2). A different marker is used for each study subject. Linear regression is shown for all subjects combined, and the equation with R2 is shown on the plot. Mean bias is displayed as a solid horizontal line, and the upper and lower LoA (mean bias ±1.96•SD*) are shown by dashed horizontal linesBack to article page
