About Masimo
Masimo is a global medical technology company renowned for its innovative non-invasive patient monitoring solutions and hospital automation platforms. For physicians, Masimo’s core offerings center on its proprietary Signal Extraction Technology (SET®) pulse oximetry, which provides accurate measurements even during patient motion and low perfusion, a critical advancement in vital sign monitoring. Beyond pulse oximetry, Masimo’s portfolio includes advanced Pulse CO-Oximetry for non-invasive measurement of various blood constituents like total hemoglobin (SpHb®) and carboxyhemoglobin (SpCO®), as well as brain function monitoring (SedLine®), regional oximetry (O3®), and capnography.
Increasingly, Masimo leverages artificial intelligence (AI) to enhance clinical decision-making and streamline workflows. Its Hospital Automation™ platform, driven by AI, integrates data from Masimo and third-party devices into electronic medical records (EMRs), aiming to provide a more complete patient picture and proactively identify potential deterioration. Solutions like Visual Clinical Activity Monitoring (VCAM™) utilize AI for hand hygiene compliance, demonstrating Masimo’s commitment to improving patient safety and operational efficiency through intelligent systems. The company also extends its monitoring capabilities to remote and home care settings with platforms like Masimo SafetyNet®, which can integrate with wearables like the Masimo W1™ medical watch.
Masimo’s mission is to improve patient outcomes and reduce the cost of care by expanding non-invasive monitoring to new applications and locations, from acute care to home environments. The company emphasizes continuous innovation, clinical evidence, and patient safety, aiming to transform patient care through advanced monitoring and data-driven insights.

What Physicians Need to Know
For physicians, Masimo stands out due to its clinically validated accuracy, particularly with SETu00ae pulse oximetry, which performs reliably even during patient motion, low perfusion, and across diverse skin tones, significantly reducing false alarms. The rainbowu00ae technology offers a comprehensive, noninvasive view of patient status by monitoring parameters like total hemoglobin, reducing the need for invasive blood draws. The Rootu00ae platform centralizes various monitoring modalities, simplifying complex patient data into an intuitive display, and its expandability allows for tailored monitoring solutions. Masimo's automation and connectivity solutions, including Patient SafetyNetu2122 and Iris Gatewayu2122, streamline workflows by automating charting and providing remote clinician notifications, freeing up valuable time for direct patient care and reducing transcription errors. Furthermore, solutions like SedLineu00ae brain function monitoring aid in precise anesthesia dosing, potentially leading to faster emergence and reduced post-anesthesia complications. The ability to extend hospital-grade monitoring to the home via Masimo SafetyNetu2122 supports continuity of care, early intervention, and can contribute to reduced hospitalizations and improved patient outcomes.
Masimo's Rootu00ae platform and Iris Gatewayu2122 are designed for robust integration, serving as connectivity hubs that can centralize data from both Masimo and third-party devices. This facilitates automated electronic charting into Electronic Medical Records (EMRs) and Patient Data Management Systems (PDMS), ensuring a continuous flow of patient information across the continuum of care and breaking down data silos. Masimo also collaborates with technology leaders and offers OEM solutions, allowing their monitoring technologies to be integrated into devices from numerous third-party manufacturers, including Philips, GE Healthcare, and Mindray.
