Fig. 4.
Respiratory mechanics (parameters of the constant-phase model fitted to respiratory system impedance) of female (n = 7) and male (n = 6) mice, controls and those exposed to chronic jet lag (females, n = 7; males, n = 8). Females (left column): airway resistance, Rn (A); tissue damping, G (B); tissue elastance, H (C); and hysteresivity, Eta (D). Males (right column): airway resistance, Rn (E); tissue damping, G (F); tissue elastance, H (G); and hysteresivity, Eta (H). Data are expressed as group means ± 1 SD. *Statistical difference between controls and CJL (P < 0.05) at each positive end-expiratory pressure (PEEP) level (0, 2, 3 cmH2O).
