Mechanics of the respiratory system and its individual components analyzed in both C57BL/6J (C57; n=8) and C57BL/6×129 (C57×129; n=9) mice were assessed using a 1.2-second, 2.5 Hz forced oscillation maneuver and a 3-second low frequency forced oscillation of mutually prime frequencies between 1–20.5 Hz. Data analyzed by one-way ANOVA, presented as mean ± SE.
