The summary describes a microprocessor-based EEG monitoring system that processes EEG signals to derive a BIS variable. There is no mention of AI, ML, or related concepts in the device description, intended use, or performance studies. The studies focus on the clinical effectiveness of using the BIS variable, not on the underlying signal processing methodology.
No.
The device is an EEG monitor that aides in monitoring the effects of certain anesthetic agents and can help reduce the incidence of awareness with recall during anesthesia and sedation. It is for monitoring and not directly treating conditions or diseases.
Yes
The device is intended to "monitor the state of the brain by data acquisition of EEG signals" and aid "in monitoring the effects of certain anesthetic agents," suggesting it is used to assess physiological conditions.
No
The device description explicitly states it is a "microprocessor- based, 2 channel maximum EEG monitoring system," indicating it includes hardware components for data acquisition of EEG signals.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Aspect A-2000 EEG Monitor with BIS directly monitors the electrical activity of the brain (EEG signals) through sensors placed on the patient's head. It processes these signals to provide a measure of the state of the brain (BIS).
- No Sample Analysis: The device does not analyze samples taken from the body. It directly measures a physiological signal from the body.
Therefore, the device falls under the category of a physiological monitoring device, not an in vitro diagnostic device.

Intended Use / Indications for Use
The Aspect A-2000 EEG Monitor with BIS is intended for use under the direct supervision of a licensed healthcare practitioner or by personnel trained in its proper use. The BIS Monitor is intended for use on adult and pediatric patients within a hospital or medical facility providing patient care to monitor the state of the brain by data acquisition of EEG signals.
The BIS may be used as an aid in monitoring the effects of certain anesthetic agents. Use of BIS monitoring to help guide anesthetic administration may be associated with the reduction of the incidence of awareness with recall in adults during general anesthesia and sedation.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The B-Aware study was a prospective, randomized double blinded multi-center study to determine if the BIS technology reduces the incidence of awareness. 1227 were assigned to BIS monitoring, and 1228 to routine care (no BIS was used). Results of this study (n=2503) are that BIS guided anesthesia significantly reduced the incidence of awareness by 82%.
The Safe-II was a prospective cohort study undertaken to determine if BIS monitoring would result in a reduction of awareness. This study compared the patients having had BIS monitoring (n=5057) with a historical group (n=7801) that had no BIS monitoring. Results are that use of BIS significantly reduced the incidence of awareness by78%.
The Kaplan study showed the risk of awareness and recall was reduced by 78% during sedation in the ICU setting.
The AIM (Awareness Incidence and Monitoring) study was a prospective, observational, cohort, multi-center study conducted in 7 hospitals in the US. This study was undertaken to determine the current incidence of intra-operative awareness in the US. Results of this study (n=19576) are that 1-2 cases of awareness per 1000 occur in the US, and this is similar to other non-US findings (i.e. Australia and Sweden).
The fact is that there are 20 million cases of anesthesia every year in the US, and there are 20,000 - 40,000 cases of awareness per year.

Brief Description of Clinical Tests
The B-Aware study was a prospective, randomized double blinded multi-center study to determine if the BIS technology reduces the incidence of awareness. 1227 were assigned to BIS monitoring, and 1228 to routine care (no BIS was used). Results of this study (n=2503) are that BIS guided anesthesia significantly reduced the incidence of awareness by 82%.

The Kaplan study showed the risk of awareness and recall was reduced by 78% during sedation in the ICU setting.
The AIM (Awareness Incidence and Monitoring) study was a prospective, observational, cohort, multi-center study conducted in 7 hospitals in the US. This study was undertaken to determine the current incidence of intra-operative awareness in the US. Results of this study (n=19576) are that 1-2 cases of awareness per 1000 occur in the US, and this is similar to other non-US findings (i.e. Australia and Sweden).
The fact is that there are 20 million cases of anesthesia every year in the US, and there are 20,000 - 40,000 cases of awareness per year. Study results show that this number can be reduced by approximately 80% with the use of BIS monitoring, and can thus offer clinically meaningful benefit. A reduction in awareness provides a public health benefit, in that BIS technology can now provide anesthesiologists with a way to reduce this often debilitating, yet preventable medical error.
