Abstract
The anesthesia adequacy monitor measures the level of consciousness of a patient as distinguished from merely the physical paralysis of the patient. Sensors attached to the patient's face measure the micro-expression the patient is exhibiting which is normally undetectable by even a trained observer. This device amplifies the patient's expression and thereby provides both a quantative and a qualitative measure of the patient's reactions to various stimuli during apparent unconsciousness. A display is provided giving an operator a readily discernable representation of the patient's awareness. An artifact detector further enhances the device's utility by filtering out unwanted anomalies from the monitor's output. During surgery, this device can be used to maintain an adequate level of patient awareness while the patient is under anesthesia. After an event resulting in apparent unconsciousness, this device can provide a measure of the patient's true level of awareness. In this way, patient comfort is maximized and patient recovery time is minimized.
