The SedLine® Sedation Monitor is indicated for adult and pediatric patients (1 year of age and older) in the operating room (OR), intensive care unit (ICU), and clinical research laboratory. The system includes the Patient State Index (PSi), a proprietary computed EEG variable that is related to the effect of anesthetic agents. The PSi is indicated for use on adults sedated with the following agents: Alfentanil, Desflurane, Fentanyl, Isoflurane, Nitrous Oxide, Propofol, Remifentanil, and Sevoflurane. The PSi is indicated for use on pediatrics 4 years and older when sedated with the following agents: Sevoflurane, Propofol. The SedLine® is only to be used with Masimo SedLine® sensors and cables. The use of any other sensor or cable is neither supported nor recommended by Masimo and could give erroneous results. ## Device Story SedLine Sedation Monitor is a 4-channel processed EEG monitor; acquires/processes EEG signals via forehead sensors; computes Patient State Index (PSi) related to anesthetic agent effects. Used in OR, ICU, and clinical research labs by clinicians. System displays EEG waveforms, Density Spectral Array (DSA), EMG Index, Suppression Ratio (SR), and Artifact (ARTF). Output assists clinicians in monitoring brain state under anesthesia. Device consists of SedLine Module, EEG sensor, and patient cable; connects to host/backboard device (e.g., Masimo Root) for UI, power, and data storage. No hardware/software changes in this submission; expansion of PSi indications to pediatric population. ## Clinical Evidence Clinical study analyzed data from 169 pediatric patients. Performance of Pediatric PSi was evaluated against evidence of burst suppression, manual sedation scoring (UMSS), and anesthesia stages. Results demonstrated responsiveness of Pediatric PSi and supported substantial equivalence. ## Technological Characteristics 4-channel processed EEG monitor; utilizes forehead sensors for potential difference detection. PSi algorithm computes multivariate qEEG variables. Connectivity via MOC-9 interface to host device. Electrical safety per IEC 60601-1; EMC per IEC 60601-1-2. Continuous operation mode. No changes to materials, hardware, or software from predicate. ## Regulatory Identification An electroencephalograph is a device used to measure and record the electrical activity of the patient's brain obtained by placing two or more electrodes on the head. ## Predicate Devices - Masimo SedLine Sedation Monitor ([K203113](/device/K203113.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The SedLine® Sedation Monitor is indicated for adult and pediatric patients (1 year of age and older) in the operating room (OR), intensive care unit (ICU), and clinical research laboratory.

Masimo SedLine Sedation Monitor (K260880) Page 2 of 9 {6} MASIMO MASIMO CORPORATION 52 Discovery Irvine, CA 92618 ### 510(k) Summary K260880 The PSi is indicated for use on adults sedated with the following agents: Alfentanil, Desflurane, Fentanyl, Isoflurane, Nitrous Oxide, Propofol, Remifentanil, and Sevoflurane. The PSi is indicated for use on pediatrics 4 years and older when sedated with the following agents: Sevoflurane, Propofol. The SedLine® is only to be used with Masimo SedLine® sensors and cables. The use of any other sensor or cable is neither supported nor recommended by Masimo and could give erroneous results. ### 3 Technological Characteristics # *Principle of Operation* There are no changes made to the principles of operation from the previous clearance under K203113. SedLine still relies on the principle that brain activity results in electrical activity that can create detectable potential differences at the skin surface of the forehead that increases with increased brain activity and decreases with reduced brain activity. Same as the previous clearance, the PSi algorithm utilizes this relationship to establish characteristics of the EEG that can be quantified to establish multivariate combinations of quantitative EEG (qEEG) variables that are sensitive to the brain activity under changing levels of anesthesia. # *Mechanism of Action for Achieving the Intended Effect* As part of this submission, Pediatric PSi will be displayed when a SedLine Pediatric sensor is connected to the SedLine Module. There are no other changes made to the mechanism of action from the previous clearance under K203113. Same as the previous clearance, the SedLine EEG sensor is applied to the patient's forehead and connected to the SedLine Module using the SedLine patient cable. The SedLine Module is in turn connected to a host/ backboard device. ### 4 Discussion of Similarities and Differences Between Predicate and Subject Device *Similarities and Differences between Predicate and Subject Device* The subject device, SedLine Sedation Monitor, and predicate device, SedLine Sedation Monitor (K203113), have the following key similarities: - Both devices have the same intended use. - Both devices rely on the same principles of operations and mechanism of action. The subject device, SedLine Sedation Monitor, and the predicate device, SedLine Sedation Monitor (K203113), have the following key differences: Masimo SedLine Sedation Monitor (K260880) Page 3 of 9 {7} MASIMO MASIMO CORPORATION 52 Discovery Irvine, CA 92618 ## 510(k) Summary K260880 - Subject device adds expanded indications for PSi to include pediatric population.
