Product Overview
The Masimo Rad-57 9216 is a portable, handheld pulse CO-oximeter designed for reliable monitoring of oxygen saturation (SpO2), pulse rate (PR), and perfusion index (Pi). Featuring Masimo SET® Measure-through Motion and Low Perfusion™ technology, it delivers precise readings even in challenging conditions like patient motion or low perfusion. Ideal for EMS, hospitals, and clinics, this rugged, lightweight device (13 oz) supports continuous monitoring with up to 72 hours of trending memory.
The Rad-57 9216 is SpO2-enabled but upgradeable to include rainbow SET® parameters like SpHb (total hemoglobin), SpCO (carboxyhemoglobin), SpMet (methemoglobin), SpOC (oxygen content), and PVi (pleth variability index). Its intuitive interface, Low Signal I.Q.® (SIQ) indicator, and compatibility with rainbow® and reusable sensors make it versatile for adult, pediatric, and infant patients. FDA-cleared and CE-marked, it’s trusted globally, monitoring over 200 million patients annually.
Key Features
- Advanced Accuracy: Masimo SET® technology ensures ±2% SpO2 accuracy (no motion, adults/pediatrics) and ±3% (motion/low perfusion).
