Know the brain’s starting point before surgery. Watch its recovery after.
Cognitive impairment check
With the patient awake, KBO records the brain at rest, then plays brief tones through earphones and records the response. It is designed to flag cognitive impairment and alert the anesthesiologist to higher-risk patients, with a suggested medication plan.
Delirium risk assessment
As anesthesia wears off, KBO compares the recovery response with the patient’s own pre-op baseline to produce a delirium risk assessment.
Each patient is their own reference.
Comparing each patient with their own starting point is meant to reveal changes a single reading can’t.
Early and late.
Early responses reflect how sound reaches the brain. Later responses depend more on attention and cognitive context. KBO reads both.
Auditory evoked potentials across cognitive states
A paper with UC Davis anesthesiologists examines how the brain’s sound response changes across wakefulness, sleep, sedation and anesthesia.
