Figure 4

Hypoxic effects on minute phrenic (Axf Phr) and hypoglossal activity (Axf HG) and respiratory frequency (f) divided into the phases of the response in baseline conditions and following DOI and ketanserin (KS) injection. Abbreviations: C - control value before induction of hypoxia, HS - hypoxic stimulation, HD - hypoxic decline, HA- hypoxic apnea, and R- recovery. Values are means ± SE, n = 8. *Significant difference between DOI and KS group; #significant difference between Baseline and DOI group; †significant difference between Baseline and KS group; P < 0.05.
