	CX717	CX717 + Hypoxia	HPCD + Hypoxia
Right burst amplitude, a.u.	0.009 ± 0.005	0.007 ± 0.005	0.006 ± 0.005
Left burst amplitude, a.u.	0.008 ± 0.005	0.004 ± 0.002	0.006 ± 0.004
Burst frequency, bursts/min	48.8 ± 5.8	49.1 ± 7.2	47.8 ± 5.1
Heart rate, beats/min	438.4 ± 19.7	433.7 ± 16.6	430.2 ± 22.9
Mean arterial pressure, mmHg	136.7 ± 18.3	132.9 ± 19.7	138.3 ± 24.1

Data are means ± SD. There were no statistically significant differences in these parameters between treatment groups (all P = 0.1774). a.u., Arbitrary units; HPCD, 2-hydroxypropyl-β-cyclodextrin.
