Effects of the depth of anesthesia on respiratory parameters. The cycle period, expiratory duration, and inspiratory duration were measured under 2 and 0% isoflurane (Iso). For 0% isoflurane, data were obtained about 5 min after the concentration of isoflurane was switched from 2 to 0%. All three parameters were significantly prolonged by removal of isoflurane (P < 0.05, n = 8)
