| Response time (ms) | 602.7 ± 29.0 | 594.5 ± 30.1 | 0.17 |
| N1 peak amplitude (μV) | -6.3 ± 0.9 | -6.3 ± 0.9 | 0.91 |
| P2 peak amplitude (μV) | 7.4 ± 0.9 | 7.3 ± 0.8 | 0.73 |
| N1 50% peak latency (ms) | 88.5 ± 4.5 | 89.6 ± 4.6 | 0.04 |
| P2 50% peak latency (ms) | 166.8 ± 6.7 | 168.8 ± 6.6 | 0.02 |
The P values represent the results of paired Student t tests between the normoxia and the gas mixture groups.
