Post-N₂O vs. CO₂ treatment latency data (mean ± SE) on groups of piglets for Experiment 1.

Latency Variable (s) 1	CO2	Post-N2O	p-Value
Ataxia	81.43 ± 6.03	−178.96 ± 36.25 2	0.001 *
Heavy Breathing	61.61 ± 10.93	−3.21 ± 31.29 2	0.102
Open-Mouth Breathing	86.71 ± 9.82	79.87 ± 9.99	0.401
Gaping	143.57 ± 9.53	135.43 ± 13.95	0.826
Loss of Posture	125.16 ± 6.48	−75.64 ± 43.29 2	0.002 *
First Paddle Bout	616.88 ± 180.62	600.82 ± 197.94	0.564

¹ s = seconds; * p < 0.05 significant statistical difference. ² The negative value indicates that the behavior occurred while piglets were in N₂O, prior to CO₂.
