Fig. 2. Mean inspiratory burst amplitude recorded in the ipsilateral (IL) and contralateral (CL) phrenic nerves during and following hypoxia.
Data are expressed as arbitrary units (a.u.) in panel A. The data in panel B are normalized relative to baseline activity (% baseline). In panel C, changes in phrenic burst amplitude are expressed relative to the maximal response recorded during the protocol (% max). *: P < 0.05; **: P < 0.01 compared with the baseline. ##: indicates difference between CL and IL phrenic burst amplitude, P < 0.01.
