Rainbow SET technology delivers continuous, noninvasive monitoring that goes beyond standard pulse oximetry to measure carboxyhemoglobin, methemoglobin, total hemoglobin, and oxygen content alongside traditional SpO2 and pulse rate. Unlike conventional pulse oximeters that struggle with motion artifacts and low perfusion, the Radical-7’s signal extraction algorithms maintain accurate readings during patient movement and compromised circulation states.

The upgradable platform means you can add measurement parameters in the field without replacing hardware, while SatShare connectivity integrates with existing multiparameter monitors and network systems. Worth noting: the Perfusion Index with trending and PVI gives you real-time hemodynamic assessment data that helps guide fluid management decisions.

The detachable handheld design runs on battery power for transport while maintaining full monitoring capabilities. Display automatically rotates for vertical or horizontal mounting, and advanced alarms include desaturation indexing and PI Delta trends.
