Masimo

What Masimo does

Masimo is a global medical technology company that develops and manufactures noninvasive patient monitoring devices for hospitals and healthcare systems. The company's core platform is Masimo SET (Signal Extraction Technology) pulse oximetry, which uses advanced signal processing algorithms and dedicated sensor designs to deliver accurate oxygen saturation and pulse rate readings through patient motion and low perfusion, including across all skin tones. Built on this foundation, the rainbow Pulse CO-Oximetry platform extends monitoring to multiple blood constituents (SpHb, SpCO, SpMet, ORi), with additional modalities covering brain function (SedLine), regional oximetry (O3), hemodynamics (LiDCO), capnography (NomoLine), acoustic respiration rate (RRa), and the recently FDA-cleared AI-enabled opioid-induced respiratory depression detection on the wearable Radius VSM monitor.

Masimo serves acute care hospitals, academic medical centers, neonatal intensive care units, emergency medical services, government and military healthcare providers, contract research organizations, and home health programs in more than 30 countries. Its go-to-market combines a direct enterprise sales force and clinical specialist team targeting large hospital systems with an OEM licensing channel that embeds Masimo SET technology into 250+ third-party monitors manufactured by partners such as Philips, GE Healthcare, and Draeger. Revenue is generated through capital equipment sales (Root, Radical-7, Rad-97, Radius VSM, handhelds), a high-margin recurring stream of single-patient-use sensors and replacement tapes, and technology licensing royalties. Following the 2025 divestiture of the Sound United consumer audio business and the June 2026 closing of Danaher Corporation's $9.9 billion acquisition, Masimo now operates as a wholly-owned subsidiary within Danaher's Diagnostics segment, with a sharpened focus on hospital patient monitoring.

Revenue model

1. Patient Monitoring Hardware: Sale of patient monitoring devices and platforms including Root, Radical-7, Rad-97, handheld monitors, and wearable devices. These are capital equipment purchases with multi-year device lifecycles.
2. Sensors and Consumables: Recurring revenue from single-patient-use sensors (RD SET, rainbow sensors), replacement tapes, and cannulas. The company emphasizes sustainability through sensor recycling programs and replacement tape options that extend sensor life by 3.6x.
3. OEM Technology Licensing: Integration of Masimo SET technology into 250+ third-party monitors from other manufacturers. Masimo provides technology licensing to original equipment manufacturers who incorporate the technology into their devices.

Core offering

Masimo develops, manufactures, and sells noninvasive patient monitoring devices and technologies used in hospitals and clinical settings. Its core offering is the SET (Signal Extraction Technology) pulse oximetry platform, expanded through rainbow Pulse CO-Oximetry into multi-parameter monitoring, and complemented by brain function, hemodynamic, capnography, wearable, and remote patient monitoring products sold with recurring single-patient-use sensors.

Product overview

Masimo offers a comprehensive patient monitoring ecosystem centered on its proprietary SET (Signal Extraction Technology) pulse oximetry platform. The core Root monitoring platform serves as an expandable hub that integrates multimodal monitoring capabilities including bedside monitors (Radical-7, Rad-97), wearable devices (Radius VSM with AI-enabled OIRD detection, MightySat Rx, Masimo W1), handheld devices (Rad-G, Rad-57), and advanced sensors. The rainbow Pulse CO-Oximetry technology extends monitoring with multi-wavelength sensors for hemoglobin, methemoglobin, and carboxyhemoglobin. Specialized monitoring includes SedLine brain function monitoring, O3 regional oximetry, LiDCO hemodynamic monitoring, NomoLine capnography, and rainbow Acoustic Monitoring for respiration rate. Connectivity solutions (iSirona, Iris Gateway) enable integration with third-party devices and EMR systems, while Patient SafetyNet and Masimo SafetyNet provide remote monitoring and telehealth capabilities.

Direct peers

• GE HealthCare: GE HealthCare competes head-to-head with Masimo in hospital patient monitoring and is also an OEM licensee of Masimo SET/rainbow technology. Overlap spans bedside monitors, anesthesia monitoring, and integrated care-area solutions purchased by the same health system buyers.
• Nihon Kohden: Nihon Kohden is a Japan-based patient monitoring specialist with strong presence in Asia and growing U.S. share, directly competing with Masimo in bedside monitors, EEG and pulse oximetry. Comparable hospital-focused business model with installed-base sensors and OEM integrations.
• Drägerwerk: Draeger is a leading ICU, OR and neonatal monitoring vendor that both competes with Masimo and licenses SET for its own monitor platforms. The companies sell into overlapping anesthesia, NICU and critical care buying committees across Europe and the U.S.
• Medtronic: Medtronic owns Nellcor pulse oximetry and a broad patient monitoring portfolio that directly competes with Masimo SET in hospitals. Both companies sell pulse oximeters, sensors and integrated bedside monitoring to the same acute-care customers.
• Royal Philips: Philips is one of Masimo's largest OEM partners (IntelliVue platform) and a direct competitor in multiparameter patient monitoring across ICU, OR and general care. Philips and Masimo increasingly compete for hospital monitoring contracts while also deepening integration partnerships.
• Edwards Lifesciences: Edwards' hemodynamic monitoring franchise (FloTrac, ClearSight, HemoSphere) competes with Masimo's LiDCO-based cardiac output and stroke volume offerings in the OR and ICU. Both companies target perioperative goal-directed therapy protocols with continuous beat-to-beat hemodynamic data.

Broad incumbents

• Mindray: Mindray is a large Chinese medical device manufacturer offering patient monitoring, pulse oximetry and in-vitro diagnostics to hospitals globally. While broader than Masimo, it is a meaningful competitor in mid-tier hospital monitors and OEM-grade pulse oximetry, particularly in emerging markets.
• ICU Medical: ICU Medical owns the Smiths Medical portfolio including patient monitoring and infusion devices that overlap with Masimo's acute-care footprint. Both companies sell into hospital med-surg, ICU and anesthesia workflows, though ICU Medical is more diversified across IV therapy and critical care.

Emerging players

• Nonin Medical: Nonin is a U.S.-based specialist in pulse oximetry and capnography devices, competing most directly with Masimo's handheld and fingertip offerings (Rad-G, Rad-57, MightySat). A focused niche player with overlapping sensor technology but a smaller commercial footprint than Masimo.
• Spacelabs Healthcare: Spacelabs provides patient monitoring, anesthesia delivery and diagnostic cardiology solutions to hospitals and clinics, competing with Masimo in multiparameter bedside monitoring. Comparable focus on smaller and mid-sized hospital systems and on cardiology/cardiac telemetry.
