We investigated the effect of sleep on blood pressure control in seven @entity742 aged 10-14 days. Each lamb had previously been anesthetized and instrumented for measurements of electrocorticogram, electron-oculogram, nuchal and diaphragm electromyograms, pulmonary blood flow (electromagnetic flow transducer), and @entity551 . The @entity742 were allowed to recover from surgery at least 3 days before they were studied. Measurements were made at the highest and lowest mean aortic pressure during quiet wakefulness, quiet sleep, and @entity25 . The lowest values of mean aortic pressure progressively decreased as the animals went from quiet wakefulness to quiet @entity25 . Mean aortic pressure was most variable during @entity25 . During @entity25 , transient @entity101 episodes were superimposed upon a tonic @entity551 phase. During the transient @entity101 episodes in @entity25 , changes in mean aortic pressure were primarily caused by an increase in systemic vascular resistance rather than by changes in cardiac output. Heart rate was always lower during @entity25 than during quiet wakefulness or quiet sleep. These results provide evidence that sleep state has a marked influence on blood pressure control in @entity742 .
