TetraGraph – Precision Neuromuscular Monitoring for Every Patient
TetraGraph is an advanced, EMG-based monitoring system designed to provide quantitative, real-time assessment of neuromuscular function during anesthesia. Built on cutting-edge electromyography (EMG) technology and powered by proprietary Adaptive Intelligence™ algorithms, TetraGraph delivers unmatched accuracy and reliability—even in complex surgical environments.
Why TetraGraph?
Residual neuromuscular blockade (rNMB) remains a significant risk in anesthesia care, leading to complications such as airway obstruction and delayed recovery. TetraGraph helps clinicians detect, manage, and prevent rNMB by offering precise, continuous monitoring throughout the perioperative process.
Key Features & Benefits
Unmatched Accuracy: EMG technology measures true muscle response, unaffected by arm positioning or external movement—ideal for robotic surgery and tuck-arm cases.
Comprehensive Monitoring: Displays Train-of-Four (TOF), TOF Ratio, Post-Tetanic Count, and Single Twitch for complete neuromuscular assessment.
Adaptive Intelligence™: Advanced algorithms filter out noise and adapt to patient-specific conditions, ensuring consistent and reliable readings.
Patient-Centric Design: Multiple sensor options, including pediatric and sensitive-skin variants, provide comfort and flexibility for all patient types.
Seamless Connectivity: Integrates with leading anesthesia monitors and electronic health record systems for automated documentation and streamlined workflows.
Guideline Compliance: Supports ASA and ESAIC recommendations, helping clinicians meet best-practice standards and improve patient safety.
Clinical Impact
By reducing the risk of residual blockade and optimizing reversal timing, TetraGraph enhances patient outcomes, minimizes complications, and can significantly lower healthcare costs. Hospitals using TetraGraph report improved efficiency and measurable savings.
Designed for Modern ORs
Compact, portable, and intuitive, TetraGraph fits effortlessly into any operating room setup. Its clear interface, trend graphs, and one-touch operation make it easy to use—even in high-pressure environments.
Empower your anesthesia team with the confidence of accurate neuromuscular monitoring. Choose TetraGraph—because precision matters.

Documentation
EMG-based Train-of-Four technology
TetraGraph® by Senzime™ is an advanced EMG-based Train-of-Four monitor for quantitative neuromuscular blockade management. Using a proprietary electromyography algorithm, it delivers accurate, real-time TOF ratios to guide NMBA dosing and reversal, ensuring safe extubation. Portable, easy to use, and compliant with ASA and ESAIC guidelines, TetraGraph® enhances patient safety and supports ERAS protocols.
Level-of-Block Gauge™
Level-of-Block Gauge™ provides clinicians with clear, real-time visualization of neuromuscular block depth across all anesthesia phases. Integrated into TetraGraph®, it simplifies interpretation of Train-of-Four and Post-Tetanic Count data, enabling precise NMBA dosing and reversal decisions. Built on advanced EMG algorithms and real-world patient data, it enhances safety and optimizes recovery.
Connectivity
Connected Workflow integrates TetraGraph® seamlessly with PDMS, patient monitors, and EHR systems via Capsule Neuron®, Axon™, and BeneLink®. This connectivity streamlines data flow, enhances documentation accuracy, and supports clinical decision-making—delivering a fully connected anesthesia monitoring ecosystem for improved efficiency and patient safety.
Adult Sensor Placement
TetraSens® Adult sensor delivers accurate EMG monitoring for neuromuscular block management. Its ergonomic design ensures secure placement and strong signal quality on adult patients, even in challenging conditions. Integrated with TetraGraph®, it provides continuous TOF data without calibration, supporting precise NMBA dosing and safe recovery before extubation.
Pediatric Sensor Placement
TetraSens® Pediatric sensor ensures safe, accurate EMG monitoring for infants ≥1 month. Its low-profile, flexible design protects delicate skin while providing strong signal feedback for correct placement—even in challenging cases. Integrated with TetraGraph®, it delivers continuous TOF data without calibration, enabling precise dosing and full recovery before extubation.
