Table 6 The number of measurements and number of corresponding patients for dichotomized BIS and RASS categories

From: Sedation assessment in a mobile intensive care unit: a prospective pilot-study on the relation of clinical sedation scales and the bispectral index

 

RASS ≥0

RASS <0

BIS >80

31 measurements from 8 patients

22 measurements from 10 patients

BIS ≥80

1 measurement

319 measurements from all patients

  1. Detection of patient-awakening (defined as RASS ≥0) by means of BIS monitoring (threshold of BIS >80) was highly sensitive: sensitivity 0.97 (CI 0.89, 1.00); positive predictive value 0.59 (CI 0.45, 0.71).
