Figure 7. Responses of mean arterial pressure (MAP) and renal sympathetic nerve activity (RSNA) to 4% isoflurane for 5 min in group 2 (a baroreceptor-deafferented rabbit). RSNA increased to a maximum at 2 min after initiating the inhalation of isoflurane, and then MAP began to decrease soon after the start of inhalation with a small notch at 2 min.
