This study sought to establish quantitative criteria for @entity8053 in artificially ventilated @entity1 with @entity5011 ( @entity5011 ). Such criteria would help to identify @entity1 at risk for @entity65 . This retrospective controlled clinical study compared hourly cardiovascular monitoring data from 36 successive, artificially ventilated @entity5011 @entity1 with that from 11 artificially ventilated control @entity1 with @entity1737 . Tolerance limits for daily means, extremes, and variations in @entity551 (BP) were estimated from the most abnormal subgroups of the treatment days of our control @entity1 . These exceeded previously suggested arbitrary cutoff values for @entity8053 . The range in systolic BP was increased in 27 @entity5011 @entity1 , despite an upper limit of normal (85 mmHg) that was double the value suggested in previous work. All 16 @entity1 with mean systolic BP above 165 mmHg also had persistent @entity591 (mean HR > 125 bpm), or were treated with beta-blockers. This pattern of sympathetic @entity2915 was combined with probable vagal @entity2915 ( @entity1168 < 48 bpm) in 6 @entity1 . @entity551 (minimal systolic BP < 85 mmHg) and unprovoked @entity1168 indicated sympathetic hypoactivity in 3 @entity1 . Except in one @entity1 who suffered from @entity1167 on his first day on the ICU, all episodes of @entity1168 were preceded by increased daily systolic BP variation (> 85 mmHg), which thus proved to be a sensitive and prognostically valuable indicator of @entity8053 in @entity5011 .
