Masimo 95166 MightySat Rx Fingertip Pulse Oximeter, SpO2, Perfusion Index, RRp

Masimo 95166 MightySat® Rx, Clinically Validated Fingertip Pulse Oximeter with SET® Technology, PVi®, and RRp® Monitoring

The Masimo MightySat® Rx is a fingertip pulse oximeter engineered for wireless spot-check pulse oximetry in clinical and professional settings. Powered by Masimo Signal Extraction Technology® (SET®), it delivers five key physiological measurements within seconds, accessible in just two easy steps via an intuitive touchscreen interface.

Unlike standard fingertip oximeters, the MightySat Rx measures Respiration Rate from the Pleth (RRp®) and Pleth Variability Index (PVi®), parameters typically reserved for bedside monitoring devices. This makes it a uniquely capable tool for clinicians requiring reliable, multi-parameter spot-check assessment in a compact form factor.

Masimo SET® Accuracy Across Challenging Conditions

Masimo SET® pulse oximetry is clinically proven to measure accurately through motion and low perfusion conditions, scenarios where conventional pulse oximeters frequently fail. This accuracy extends across diverse patient populations and skin tones, providing clinicians with confidence in the data delivered at the point of care.

Wireless Connectivity and Data Sharing

The Bluetooth® LE-equipped model integrates with the Masimo SafetyNet® App on compatible smart devices, enabling clinicians to view, trend, and share parameter data including the pleth waveform. This connectivity supports continuity of care and remote patient monitoring workflows without requiring dedicated hardware infrastructure.
