Table 4 Accuracy of SpHb by PaCO2 range.
PaCO2 <40 mmHg (n=26) | 40 mmHg ≤PaCO2 (n=14) | P value | |
---|---|---|---|
Bias (95% CI) (g/dL) | −0.60 (−1.18 to −0.02) | −0.57 (−1.15 to 0) | 0.948 |
95% Limit of agreement (g/dL) | −3.41 to 2.21 | −2.52 to 1.38 | |
Correlation coefficient (95% CI) | 0.55 (0.20 to 0.77) | 0.18 (−0.39 to 0.65) | 0.235 |
|SpHb–tHb| (g/dL) | 1.25±0.59 | 1±0.51 | 0.033 |
≤1.5 g/dL | 15 (58%) | 11 (79%) | 0.299 |
1.5 g/dL | 11 (42%) | 3 (21%) | |
Values are presented as number (%). SpHb – continuous and non-invasive hemoglobin monitoring; tHb – laboratory hemoglobin; PaCO – arterial carbon dioxide pressure. |
