Masimo MightySat® Rx – Fingertip Pulse Oximeter with Advanced SET® Technology

The Masimo MightySat® Rx is a professional-grade fingertip pulse oximeter designed for clinicians, athletic performance monitoring, and health-conscious individuals who demand accuracy—especially when motion, low perfusion, or real-world conditions make conventional pulse oximeters unreliable. Powered by Masimo Signal Extraction Technology® (SET®), the same technology used in top hospitals worldwide, MightySat Rx delivers hospital-level performance in a compact, touchscreen device. 

 

Why Choose the MightySat® Rx?

Unmatched Accuracy in Challenging Conditions

Most pulse oximeters struggle with cold hands, movement, or poor circulation. MightySat Rx overcomes these limitations with clinically proven SET® Measure-through Motion and Low Perfusion™ performance, trusted in the care of over 200 million patients annually. 

Five High-Value Parameters, Not Just SpO₂

The device measures far more than basic oxygen saturation and pulse rate. It provides deeper clinical insight through:

  • SpO₂ (Oxygen Saturation)*

  • PR (Pulse Rate)*

  • Pi (Perfusion Index)

  • PVi® (Pleth Variability Index)

  • RRp® (Respiration Rate from the Pleth, 4–70 RPM range) 

These expanded parameters help clinicians and trained users evaluate respiratory effort, perfusion quality, hydration status, and hemodynamic changes.

 

Premium Features That Enhance Every Measurement

High-Resolution Rotating Touchscreen

A bright, 150-degree viewing-angle display gives crystal-clear visibility of all parameters: SpO₂, PR, waveform data, and trending—at a glance. 

Advanced Plethysmographic Waveform

The MightySat Rx displays a real-time pleth waveform for deeper clinical interpretation, plus Signal I.Q.®, which shows accuracy confidence for each reading. 

Soft, Flexible Finger Pad

Designed for comfort and stability, reducing artifacts and ensuring secure, repeatable measurements. 

Durable, Lightweight, and Built for Every Environment

With an IP23 ingress rating and compact 73 g weight, it’s ideal for clinics, home use, EMS, training, and athletic performance monitoring. 

 

Optional Bluetooth LE: Connect, Track & Share

The Bluetooth-enabled model pairs with the Masimo SafetyNet® app, allowing you to:

  • View a high-resolution pleth waveform

  • Trend data over time

  • Share results via email for remote clinical review

  • Store sessions for documentation or performance tracking

Perfect for telehealth and remote monitoring workflows. 

 

Comparison Advantage

Compared to traditional pulse oximeters like the Nonin® Onyx® II 9560, the MightySat Rx offers:

  • Advanced SET® technology

  • Pi, RRp, and PVi parameters

  • Waveform display

  • Customizable touchscreen settings

  • App integration (Bluetooth models)

This makes it a significantly more capable and clinically-informative device.
