Mean arterial pressure, heart rates, and respiratory rates recorded from rats during four baseline periods before 7 days of normoxia or chronic intermittent hypoxia

	Baseline Period	MAP, mmHg	HR, bpm	RR, bpm
CON	0800–1600	93.9 ± 3.8	346 ± 6	100 ± 2
n = 7	1800–0600	98.2 ± 4.5	411 ± 3	99 ± 1
CIH	0800–1600	91.1 ± 1.4	318 ± 4*	99 ± 2
n = 14	1800–0600	94.7 ± 1.5	372 ± 4*	101 ± 1

Data are expressed as means ± SE. Averages were calculated for 0800–1600 when the intermittent hypoxia exposures occurred during the chronic intermittent hypoxia (CIH) protocol or for 1800–0600, which was the dark phase. MAP, mean arterial pressure; HR, heart rate; RR, respiratory rates; CON, control.
