Masimo Rad-57 Pulse Co-Oximeter

The Masimo Rad-57 Pulse CO-Oximeter is a compact, handheld monitoring device designed for EMS, hospitals, and point-of-care environments. Engineered with Masimo SET and optional rainbow technology, it provides fast, non-invasive measurement of oxygen saturation, pulse rate, perfusion index, and optional advanced parameters like SpCO, SpMet, SpHb, PVi, and SpOC.

Overview

Ideal for both stationary and mobile settings, the Rad-57 offers real-time monitoring, advanced signal processing, and trending capabilities in a durable, portable form factor. With its rugged design, 72-hour memory, and operation on standard AA batteries, it is well-suited for critical care transport, field response, and high-demand hospital environments. Visual and audible alarms, along with signal quality indicators, help clinicians respond quickly to changes in patient status.
