Masimo Receives CE Mark for AI-Powered smartSedLine Brain Function Monitor to Advance Anesthetic Management
Masimo, a Danaher company and a specialist in diagnostic and patient-monitoring technologies, has announced that its next-generation smartSedLine™ brain function monitor has received the CE Mark. The regulatory milestone supports the company’s efforts to expand advanced brain monitoring capabilities and provide clinicians with more responsive information for managing patients during anesthesia.
The smartSedLine system incorporates an artificial intelligence-powered Patient State Index (PSi) algorithm designed to provide greater responsiveness to changes in underlying brain activity while maintaining stability in challenging monitoring conditions. The technology represents an evolution of Masimo’s existing SedLine brain function monitoring platform and is intended to help clinicians better assess a patient’s sedation state throughout anesthesia.
The CE Mark is an important step in making the technology available in applicable European markets. It also highlights Masimo’s broader focus on applying advanced algorithms, artificial intelligence and physiological monitoring technologies to clinical decision-making.
Advancing Brain Function Monitoring During Anesthesia
Anesthesia management requires clinicians to continuously assess how individual patients are responding to anesthetic medications. Patients can respond differently to anesthesia depending on factors such as age, health status, neurological condition and other clinical circumstances.
Brain function monitoring can provide additional information that complements conventional clinical observations and other physiological measurements. By continuously analyzing electroencephalogram (EEG) signals, brain monitoring technologies can provide clinicians with information about changes in brain activity during anesthesia.
Masimo’s smartSedLine is designed to build on this approach. The system continuously processes and displays four real-time bilateral frontal EEG waveforms, allowing clinicians to observe brain activity from both sides of the frontal region.
The device also generates several parameters intended to assist healthcare professionals in assessing a patient’s anesthesia state and overall brain function.
One of its key outputs is the Patient State Index, or PSi. The index ranges from 0 to 100 and is designed to reflect the patient’s level of sedation. By providing a continuously generated index, the technology is intended to help clinicians monitor changes in sedation throughout the anesthetic process.
AI-Powered Patient State Index
A major feature of smartSedLine is its updated PSi algorithm, which incorporates artificial intelligence techniques to improve the responsiveness and stability of the index.
According to Masimo, the new algorithm is designed to respond more effectively to changes in underlying brain activity during anesthesia. This is particularly relevant during induction, when the patient’s brain activity can change rapidly as anesthetic agents take effect.
The company says that smartSedLine provides a more responsive PSi during induction compared with the previous-generation SedLine algorithm. Faster responsiveness may provide clinicians with additional information during a critical stage of anesthesia management.
The system is also designed to provide increased PSi stability when EEG power is low. Low EEG power can present challenges when interpreting brain activity, particularly among certain patient populations.
Masimo specifically identifies geriatric and critically ill patients as groups in which low EEG power can be an issue. Maintaining a stable and meaningful index in these circumstances can therefore be important for clinicians seeking consistent information about a patient’s brain state.
By addressing both responsiveness during induction and stability during low EEG power, smartSedLine is intended to provide a more reliable representation of underlying brain activity.
Supporting More Individualized Anesthetic Management
Patients do not necessarily respond to anesthesia in the same way. The amount and effect of anesthetic medication can vary from one individual to another, making continuous monitoring an important part of clinical management.
Masimo believes that smartSedLine can help clinicians obtain additional information to support individualized anesthesia care. Rather than relying exclusively on a single clinical observation, healthcare professionals can use continuously processed EEG information alongside other available patient data.
The PSi is designed to translate complex EEG information into a numerical index that can be monitored over time. This can potentially make changes in brain activity easier to identify and interpret within the broader context of anesthesia management.
The company’s objective is not simply to provide another measurement but to develop technology that can turn complex physiological signals into actionable clinical information.
As anesthesia progresses, clinicians can observe changes in EEG waveforms and associated parameters while monitoring the PSi. The combination is intended to provide a broader picture of how the patient’s brain is responding during care.
Addressing Challenges in Older and Critically Ill Patients
The stability of brain monitoring information can become particularly important when patients have low EEG power. According to Masimo, this can occur in certain geriatric and critically ill patients.
These patient populations can present additional challenges for clinicians because physiological responses may differ from those observed in healthier or younger individuals. A monitoring system that remains stable when EEG signals are relatively low could therefore provide useful supplementary information.
SmartSedLine’s updated algorithm is designed specifically to improve stability under these conditions. Masimo says this enhancement works alongside improved responsiveness during induction to create a PSi that more closely reflects the patient’s underlying brain activity.
The goal is to provide clinicians with information that remains useful across different stages and clinical conditions rather than focusing solely on one portion of the anesthesia process.
Four Bilateral EEG Waveforms
The smartSedLine platform continuously processes four real-time bilateral frontal EEG waveforms. EEG monitoring measures electrical activity generated by the brain, and the information can provide insight into changes in brain function.
By displaying multiple waveforms from both sides of the frontal region, the system provides clinicians with continuous information rather than a single isolated measurement.
The EEG information is processed in real time, allowing the system to generate the PSi and other parameters used to assess the patient’s anesthesia state.
This combination of raw or processed EEG information and algorithm-generated indices is intended to help bridge the gap between complex physiological data and clinical interpretation.
The approach is consistent with Masimo’s broader focus on developing monitoring technologies that provide clinicians with continuous physiological information at the point of care.
Comments From Masimo Leadership
Dr. Basil Matta, Consultant in Critical Care, Affiliated Professor at the University of Cambridge and Chief Medical Officer at Masimo, highlighted the need for monitoring technologies that can respond to rapid changes in brain activity while remaining reliable under difficult conditions.
According to Matta, the company is applying advanced AI techniques to brain function monitoring to develop a more responsive Patient State Index.
He emphasized that the improvements in responsiveness during induction and stability under low EEG power are intended to give clinicians meaningful insights that can support more individualized anesthetic management.
The comments reflect Masimo’s broader strategy of using advanced computational techniques to improve physiological monitoring. Artificial intelligence can potentially assist in processing complex biological signals and identifying meaningful changes that may be difficult to capture using simpler algorithms.
For anesthesia professionals, the ability to obtain responsive and stable information may be particularly valuable because anesthetic management can involve rapidly changing physiological conditions.
Part of Masimo’s Broader Brain Health Platform
SmartSedLine is not an isolated product development for Masimo. The company says the technology builds on its longstanding work in brain function monitoring and forms part of its broader Brain Health Platform.
The platform also includes O3® Regional Oximetry, another technology focused on monitoring brain-related physiological information.
Together, these technologies reflect Masimo’s efforts to develop a broader portfolio of tools designed to help clinicians understand brain physiology during different stages of patient care.
The company is combining continuous physiological data with increasingly sophisticated algorithms to transform complex signals into information that clinicians can use at the bedside.
This approach is particularly relevant as healthcare systems increasingly incorporate artificial intelligence and machine-learning techniques into medical monitoring. The objective is to enhance the value of physiological data without requiring clinicians to manually interpret every component of a complex signal.
Masimo and Danaher Focus on Technology Innovation
Masimo is part of Danaher, a global science and technology company with businesses operating across healthcare and other scientific fields.
The smartSedLine announcement reflects the companies’ emphasis on translating scientific and technological advances into clinical applications. Masimo describes the development as part of efforts to accelerate innovation from discovery to delivery.
Artificial intelligence is increasingly being explored across healthcare, including medical imaging, diagnostics, patient monitoring and clinical decision support. Brain function monitoring represents another area where advanced computational methods can potentially enhance the interpretation of physiological signals.
For Masimo, integrating AI into SedLine is intended to address specific challenges in anesthesia monitoring rather than simply adding AI as a standalone feature. The company has focused the algorithm improvements on two particular areas: responsiveness during induction and stability when EEG power is low.
Potential Impact on Anesthesia Care
The CE Mark for smartSedLine represents a regulatory milestone for Masimo and expands the company’s portfolio of technologies available for brain function monitoring.
For clinicians, the technology is designed to provide continuous information that can complement their assessment of patients under anesthesia. Its PSi output provides a numerical representation of sedation, while bilateral EEG waveforms and other parameters provide additional information about brain activity.
The ability to monitor these measurements continuously may help clinicians recognize changes during anesthesia and adjust their management according to the patient’s individual response.
The technology is particularly focused on improving the quality of information available during induction and in situations where EEG power is low. These improvements could be relevant in a wide range of clinical environments where anesthesia is administered and continuous brain monitoring is appropriate.
However, as with other monitoring technologies, the information generated by smartSedLine is intended to support clinical assessment rather than replace professional judgment. Clinicians must consider the complete clinical picture, including the patient’s condition, medications and other physiological measurements, when making treatment decisions.
The introduction of smartSedLine marks another stage in the development of Masimo’s brain monitoring technologies. By incorporating an AI-powered algorithm into its next-generation SedLine platform, the company is seeking to improve how EEG-derived information is processed and presented during anesthesia.
The CE Mark provides an important regulatory milestone for the product and supports its availability in relevant European markets.
As healthcare continues to adopt AI and advanced data-processing technologies, systems such as smartSedLine demonstrate how artificial intelligence can be integrated into established medical monitoring platforms. Rather than replacing conventional physiological measurements, the technology is designed to enhance the interpretation of continuous brain activity data.
Masimo’s continued development of its Brain Health Platform also suggests that the company intends to expand its focus on technologies capable of providing clinicians with deeper insights into neurological and physiological conditions.
With smartSedLine, the company is combining bilateral EEG monitoring, advanced algorithms and AI techniques to deliver a more responsive and stable Patient State Index. The ultimate objective is to help healthcare professionals better understand individual patient responses to anesthesia and make more informed decisions throughout the course of care.
The CE Mark therefore represents both a regulatory achievement and a significant step in Masimo’s ongoing effort to advance brain function monitoring and bring more sophisticated patient-monitoring technologies into clinical practice.
