Description
Nonin Model 7500FO Fiber Optic Tabletop Pulse Oximeter for MRI Suites with 70 Hour Memory and Alarms
The Nonin Model 7500FO is a fiber optic tabletop pulse oximeter built for monitoring patients inside MRI environments. Its fiber optic sensor path keeps magnetic components away from the patient while the monitor stays outside the scan room's high field area.
- Fiber optic sensor system designed for MRI suite monitoring
- 70 hours of memory with PureSAT signal processing
- Battery operation for in-scan use, up to 16 hours
- Alarms and patient security mode carry over from the Model 7500 platform
Model 7500FO Fiber Optic Oximetry for MRI Monitoring
Magnetic resonance suites rule out conventional oximeters at the bore, because standard sensor cables and electronics cannot go where the field is strongest. This model answers that constraint with fiber optic sensors that carry light instead of electrical signals to the patient. The monitor itself delivers the familiar Model 7500 feature set, including PureSAT processing, audible and visual alarms and 70 hours of stored data. Fiber optic sensor accuracy is declared at 70 to 100 percent saturation within 2 digits, matching the performance clinicians expect from the platform. During scans the unit runs on its internal battery for up to 16 hours, and the patient security mode keeps configured settings from being changed mid procedure. Analog output and nVISION compatibility support documentation once the patient leaves the suite.
Features and Benefits
MRI Suite Design

Why Imaging Centers Choose the Model 7500FO
MRI monitoring is a narrow job that general purpose oximeters cannot safely fill. A purpose built fiber optic system removes the workaround culture around scan room monitoring and replaces it with a declared, supported configuration.
- Purpose Built for the Suite – fiber optic sensing is the manufacturer specified route to oximetry during scans.
- Familiar Platform – staff who know the Model 7500 already know this monitor's alarms, display and memory.
- Session Records Kept – 70 hours of memory supports post procedure documentation and review.
- Long Battery Runtime – up to 16 hours covers extended imaging schedules without a mid day swap.
Manuals and Troubleshooting Guides
Frequently Asked Questions (FAQs)
Why does MRI monitoring need a fiber optic oximeter?
Standard sensor cables contain metallic components that cannot be used safely in the scanner's magnetic field. Fiber optic sensors transmit light instead, so the sensing path stays non metallic at the patient.
Which sensors does the 7500FO use?
It uses Nonin fiber optic sensors, the 8000FC adult and pediatric sensor and the 8000FI infant and pediatric sensor. Both are listed separately in the oximeter accessories range.
How long does the battery last in the suite?
The internal battery provides up to 16 hours of operation. The manufacturer specifies battery operation while the monitor is used in the MR environment.
Does it store monitoring data?
Yes. The memory holds 70 hours of data, and downloads work with nVISION data management software.
What warranty covers the 7500FO?
Nonin covers the monitor with a 3-year warranty. The operator manual states the full terms.
