Table 1 Hemodynamic data (mean ± SD, n = 6)

	CTL	PPH	APH
Pm (mmHg)	14.8 ± 1.8	21.9 ± 2.7^a	21.2 ± 2.9^c
Pp (mmHg)	7.5 ± 2.4	17.8 ± 4.7^a	11.8 ± 3.5^a^c
PF (mL/s)	32.7 ± 5.0	36.4 ± 6.0	35.5 ± 5.4
HR (beats/min)	110 ± 23	111 ± 28	105 ± 19
ZO (dyne.s/cm⁵)	621 ± 49	961 ± 190^a	917 ± 180^a
ZC (dyne.s/cm⁵)	82 ± 20	167 ± 60^a	98 ± 21^c
Cp (mL/mmHg)	2.63 ± 0.9	1.16 ± 0.36^a	1.87 ± 0.37^c

CTL: Control; Cp: Capacitance index; HR: Heart rate; PPH: Passive pul-monary hypertension; APH: Active pulmonary hypertension; Pm and Pp: Mean and pulse pulmonary arterial pressure, respectively; PF: Pulmonary flow; ZO and ZC: Total and characteristic impedances, respectively.
