The effect of age on the measures of SpO2.
| Average Age (years) | Mean SpO2 (%) | Standard Deviation of SpO2 (%) | DFA (α1) | DFA (α2) | Sample entropy | |
|---|---|---|---|---|---|---|
| Participants < 35 | 21.1 ± 1.4 | 98.02 ± 0.81 | 0.68 ± 0.22 | 1.28 ± 0.098 | 0.87 ± 0.11 | 0.86 ± 0.29 |
| Participants > 35 | 49.9 ± 10.4 | 97.31 ± 1.59 | 0.75 ± 0.28 | 1.34 ± 0.11 | 0.88 ± 0.086 | 0.90 ± 0.42 |
| p-value | 0.000* | 0.090 | 0.408 | 0.102 | 0.78 | 0.739 |
Values are displayed in the format of means ± SD. The P-values are calculated using the Student's t-test and significance was set at p < 0.05.
