Respiratory mechanics were measured in mice subjected to high tidal volume (HV_T) ventilation. Values represent mean ± SEM after 60 min (1 h HV_T) and at the end of HV_T ventilation (maximum 240 min).

^*P < 0.05 vs. 1 h HV_T.

^†P < 0.05 vs. vehicle.

H₂S = hydrogen sulfide; Na₂S = sodium sulfide.
