Metrics of impedance (Z₀, Z_C, R_W) for CTL (n = 6) and HPH (n = 5) mouse lungs in the baseline SMC tone state and with Y27632

	Z₀, mmHg · min · ml⁻¹		Z_C, mmHg · min · ml⁻¹		R_W (dimensionless)
	CTL	HPH	CTL	HPH	CTL	HPH
Baseline	2.1 ± 0.4	4.0 ± 0.7^*	0.21 ± 0.01	0.194 ± 0.009	0.81 ± 0.05	0.91 ± 0.01^*
Y27632	1.5 ± 0.2^†	2.2 ± 0.2^*^†	0.22 ± 0.01	0.187 ± 0.005^*	0.73 ± 0.03^†	0.84 ± 0.02^*^†

Values are means ± SD. Z₀, 0-Hz impedance; Z_C, characteristic impedance; R_W, wave reflection; CTL, control; HPH, hypoxic pulmonary hypertension; SMC, smooth muscle cell.

P < 0.05 vs. CTL;

^†

P < 0.05, for change from baseline to Y27632.
