The document describes a device that processes EEG signals to derive a "Patient State Index (PSI)," which is a "proprietary computed EEG variable." While this involves signal processing and potentially complex algorithms, there is no mention of AI, ML, or related terms like DNN. The validation study focuses on comparing the new algorithm to a predicate algorithm, not on training or testing an AI/ML model.
No
The device monitors the state of EEG signals and provides information related to the effect of anesthetic agents but does not actively administer treatment or alter the patient's condition.
No
The device monitors the state of EEG signals and provides computed variables related to the effect of anesthetic agents. While it provides information, it does not explicitly state that it diagnoses a condition or disease, but rather monitors a physiological state influenced by medication.
No
The device description explicitly lists hardware components: Root, SedLine Module, SedLine Patient Cable, and SedLine Sensor.
Based on the provided information, the SedLine Sedation Monitor is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- SedLine's Function: The SedLine Sedation Monitor directly monitors physiological signals (EEG) from the patient's body. It processes these signals to provide information about the patient's state of sedation, which is related to the effect of anesthetic agents.
- Lack of Specimen Analysis: The device does not involve the collection or analysis of any specimens taken from the body. It is a patient-connected device that measures electrical activity directly.
Therefore, the SedLine Sedation Monitor falls under the category of a patient-monitoring device, not an In Vitro Diagnostic device.

Description of the test set, sample size, data source, and annotation protocol
Validation of the subject algorithm was performed by retrospective analysis of the clinical data in 100 surgical patients (age: 18-77 years, male/female: 26/74). The clinical data was collected at the operating room from three different hospitals. Clinical data used for the analysis includes continuous EEG, anesthetic drug dose information, and other physiological vital signs such as mean arterial blood pressure and heart rate.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical Testing:
- Electrical safety testing per IEC 60601-1
- EMC testing per IEC 60601-1-2
- Alarm testing per IEC60601-1-8
- Usability testing per FDA Human Factors and Usability Draft Guidance
- Software verification per FDA Software Guidance
- Mechanical Testing per EN 60601-2-26
- Environmental testing per EN 60601-2-26
The results demonstrate that all requirements and performance specifications were satisfied, and that the subject device is substantially equivalent to the predicate device.
The multi-taper DSA evaluation was conducted as part of the "Software verification per FDA Software Guidance." The tests validated DSA by comparing multi-taper DSA against the predicate's Hanning DSA, both computed for a known input signal. The following functionality were tested for multi-taper DSA:
- Dynamic range of the power spectrum,
- Frequency range,
- Spectral Edge Frequency, and
- High-contrast feature of the multi-taper DSA against the predicate's Hanning DSA.
Clinical Testing:
Validation of the subject algorithm was performed by retrospective analysis of the clinical data in 100 surgical patients (age: 18-77 years, male/female: 26/74). The subject PSi algorithm was compared to the predicate PSi algorithm. The clinical data was collected at the operating room from three different hospitals. Clinical data used for the analysis includes continuous EEG, anesthetic drug dose information, and other physiological vital signs such as mean arterial blood pressure and heart rate.
Conclusion:
The clinical and non-clinical testing provided in this 510(k) submission demonstrates that the subject device, SedLine® Sedation Monitor, is substantially equivalent to its predicate.

5.5 Technological Characteristics
5.5.1 Principle of Operation
The Patient State Index (PSI) formula was constructed based upon multivariate combinations of quantitative electroencephalogram (OEEG) variables found to be sensitive to changes in the level of anesthesia but insensitive to the specific substances producing such changes. The PSI is the result of a complex computation that combines weighted quantitative values reflecting many dimensions of brain electrical activity, such as: (1) changes in power in various EEG frequency bands, (2) changes in symmetry and synchronization between critical brain regions, and (3) the inhibition of regions of the frontal cortex.
The PSI is computed from continuously monitored changes in the OEEG during surgery, using statistical analysis to estimate the likelihood that the patient is anesthetized. The SedLine performs these computations automatically on the continuously recorded EEG after automatic removal of data contaminated with artifact from physiological and environmental signals. The computed PSI is periodically updated, displayed in numeric form, and presented in a color-coded trend graphic for monitoring the effect of certain anesthetics on the state of the brain.
5.5.2 Mechanism of Action for Achieving the Intended Effect
The SedLine EEG Sensor is noninvasively applied to the patient on one end. The other end of the SedLine EEG Sensor connects to the SedLine Module. In turn, the SedLine Module connects to a Host/Backboard device. The SedLine EEG Sensor collects patient EEG signals which are processed by the SedLine Module and displayed on the Host/Backboard device.
5.5.3 Summary of Technological Characteristics of Subject Device Compared to Predicate Device
The subject device, SedLine® Sedation Monitor, and the predicate device. Masimo Root Monitoring System (K140188), have the following key similarities:
- Both devices have the same parameters to measure patient sedation state;
- Both devices display their calculated values on a Host/Backboard device . (Masimo Root Monitoring System);
- Both devices have the same indications for use;
- Both devices have the same intended use; ●
- Both devices have the same measurement site; ●

Both devices include EEG sensors and patient cables.
The subject device and the predicate device. Root Monitoring System (K140188). differ only in the SedLine software. The differences are: -
. An optional additional DSA display is now available that uses a multi-taper window EEG to display the spectral waveform;
-
Modified Patient State Index (PSI) algorithm.
5.5.4 Non-clinical Testing
See below for the non-clinical testing that was completed.
- Electrical safety testing per IEC 60601-1
- EMC testing per IEC 60601-1-2 ●
- Alarm testing per IEC60601-1-8 ●
- Usability testing per FDA Human Factors and Usability Draft Guidance
- Software verification per FDA Software Guidance ●
- Mechanical Testing per EN 60601-2-26 ●
- Environmental testing per EN 60601-2-26
The results demonstrate that all requirements and performance specifications were satisfied, and that the subject device is substantially equivalent to the predicate device.
The multi-taper DSA evaluation was conducted as part of the "Software verification per FDA Software Guidance." The tests validated DSA by comparing multi-taper DSA against the predicate's Hanning DSA, both computed for a known input signal. The following functionality were tested for multi-taper DSA:
- Dynamic range of the power spectrum,
- Frequency range,
- Spectral Edge Frequency, and
- High-contrast feature of the multi-taper DSA against the predicate's Hanning DSA.
5.5.5 Clinical Testing
Validation of the subject algorithm was performed by retrospective analysis of the clinical data in 100 surgical patients (age: 18-77 years, male/female: 26/74). The
