Representative vasomotor challenge results obtained using epinephrine (EPI) and sodium nitroprusside (SNP) to stimulate both a spun and a sham control PIJV segment. Since SNP was not administered until a full relaxation of the tissue was observed following stimulation with EPI, SNP was administered at different times for the sham and spun PIJVs. Outer diameter measurements of each PIJV segment over the duration of the experiments were normalized to the baseline outer diameter which was measured prior to administration of the first dose of EPI.
