【正文】 ch patient What the numbers mean BIS Number ? What the numbers mean: 0 = no electrical brain activity 100 = fully awake ? For moderate sedation, aim for range from 6070, below 60 is associated with a low probability of explicit recall ? For deeper sedation, aim for range from 4060. A patient with a BIS value of less than 45 is approaching a deep hypnotic state BIS Number ? For a patient receiving neuromuscular blockage, sedation, analgesia therapy, the medication should be titrated for a BIS value between 45 and 60 SQI: Signal Quality Index ? What the numbers mean: 0 = poor quality 100 = excellent quality ? Aim for range from 80100% EMG: Electromyographic Activity ? Reflects the electrical power of muscle activity or artifact ? What the numbers mean: the higher the number, the greater the muscle activity if the EMG is high, can make the number artificially high (it incorrectly reads the increased muscle activity as increased EEG activity ? Acceptable EMG is less than 55 dB ? Optimal EMG is less than 30 dB Electrode Placement ? Prep skin with alcohol prior to electrode placement ? Electrode should be changed every 24 hours, alternating temples daily ? Look at electrode packaging for placement instructions Electrode Placement ? To ensure adequate placement and impedance, check on the screen Resources ? Guidelines and Procedure available in AACN Procedural Manual for Critical Care, Procedure 86, page 699
