Intermittent hypoxia (IH) elevates arterial blood pressure in rats. A: example illustrating ambient oxygen (top) and arterial blood oxygen saturation (bottom) levels in an unrestrained, conscious rat during exposure to IH. B: average data of mean blood pressure (MBP) in rats treated with either normoxia (control) or IH for 14 days. Values are means ± SE from control (n = 6) and IH (n = 10) rats. **Denotes P < 0.01; n.s., denotes P > 0.05 compared with MBP measured before exposures to either normoxia or IH for 14 days.
