Figure 3. Histograms illustrating (A) the effects of isoflurane (ISO) and xenon on total arterial resistance (R), (B) characteristic aortic impedance (Zc), and (C) total arterial compliance (C) in healthy (hatched bars) and cardiomyopathic dogs (solid bars) that received 1.5 minimum alveolar concentration isoflurane in the presence and absence of 30%, 50%, and 65% xenon. *P < 0.05 versus conscious (CON);[dagger] P < 0.05 versus ISO alone;[paragraph mark] P < 0.05 versus corresponding value in healthy dogs.
