Heart rate variability prior to and during aerosol challenge. The acclimation control period (0–60 min) and aerosol challenge (70–130 min, to accommodate sampling) were independently analyzed by Two-Way ANOVA and Holm-Sidak post-hoc analyses; *P < 0.05. During acclimation, OVA-sensitized mice displayed decreased SDNN (P < 0.05), LF (P < 0.025), and LF/HF (P < 0.05) compared with Alum control mice. During aerosolized Ag challenge, RMMSD (P < 0.05) and pNN6 (P < 0.05) were significantly increased in OVA-sensitized mice compared to the Alum controls.
