Figure 3
Waterfalls showing the spectra calculated under normoxia (A) and hypoxia (B) before and after selective autonomic blockade. Data sets consisting of 1,500 seconds were chosen within each condition: (A) Normoxia (N = 9); muscarinic blockade with atropine (N = 5); β-adrenergic blockade with sotalol (N = 4); and double autonomic blockade (DB; N = 9). (B) Hypoxia (FIO2: 0.05; N = 13); muscarinic blockade (N = 6); β-adrenergic blockade (N = 7); double autonomic blockade (DB; N = 13). Each spectrum was obtained following calculations of the average among all spectra of animals from the group at particular conditions. The standard error of the mean for the pooled data is omitted for clarity. For significant differences, see Table 1.
