Most patient monitoring works fine until the environment changes. Put a conventional pulse oximeter near an MRI scanner and the problem becomes immediate: copper cabling in a strong magnetic field is a safety hazard and a source of image artifact, and the monitor itself may not function reliably. That constraint does not remove the clinical need, since a sedated patient inside a scanner still requires continuous oxygen saturation monitoring, arguably more than a patient a clinician can see and speak with directly.
Fiber-optic pulse oximetry exists to solve exactly that problem, replacing the electrical signal path with an optical one. Nonin Medical has built its reputation on pulse oximetry accuracy across difficult monitoring conditions, and MediDepot carries the Nonin Model 7500FO, the brand's fiber-optic tabletop oximeter designed specifically for MR environments, giving imaging centers and hospitals a monitoring option that works where standard oximeters cannot.
Who Is This Brand For?
Nonin Medical's fiber-optic monitoring equipment is built for facilities that monitor patients inside or near MR environments. This collection is a fit for:
- Hospital and outpatient MRI and imaging centers
- Anesthesiology and sedation teams monitoring patients during scans
- Pediatric and neonatal imaging departments
- Radiology departments needing MR-safe patient monitoring
- Mobile MR facilities and imaging fleets
- Biomedical engineering teams standardizing on MR-safe equipment
Product Overview
MediDepot's Nonin Medical collection centers on the Model 7500FO Fiber Optic Pulse Oximeter, a monitor purpose-built for the unique demands of the MR suite.
Model 7500FO Fiber Optic Pulse Oximeter
The 7500FO replaces standard electrical cabling with a fiber-optic sensor and cable design, which eliminates radio frequency burns and image artifacts that copper cabling can cause near an MRI scanner. It is lightweight, compact, and portable, making it suitable for monitoring infant, pediatric, and adult patients in fixed-site or mobile MR facilities. The monitor's display includes a pulse strength bar graph, a pulse quality indicator that detects patient movement or signal changes, and a sensor fault indicator that flags a disconnected, misaligned, or incompatible sensor. This category totals 1 product.
How to Choose the Right Product
Because MRI monitoring has requirements that standard patient monitoring does not, a few factors matter most when specifying the 7500FO for your facility.
- MR compatibility. The 7500FO's fiber-optic sensor and cable design is specifically engineered for use in and around MRI scanners, where copper-cabled monitors pose a burn and artifact risk.
- Patient population. The monitor's lightweight, compact design supports infant, pediatric, and adult patients, so a single unit can cover multiple patient types across a facility.
- Power source during scans. The 7500FO runs on battery power during MR use, backed by a 30-hour minimum operating life on a full charge, so confirm your workflow allows time for recharging between cases.
- Mobile versus fixed-site use. The monitor's portable, compact form factor suits both fixed-site MR suites and mobile imaging units that move between locations.
- Data retention needs. With approximately 70 hours of onboard memory, the 7500FO can hold monitoring data across multiple cases before it needs to be offloaded.

Frequently Asked Questions
Q: Why does the 7500FO use fiber optic cabling instead of standard electrical cabling?
A: Fiber optic cabling eliminates the radio frequency burn risk and image artifacts that copper cabling can cause when used near an MRI scanner, making the 7500FO safe for continuous monitoring in MR environments.
Q: What patient populations can the 7500FO monitor?
A: The 7500FO is lightweight, compact, and portable, and is designed to monitor infant, pediatric, and adult patients in both fixed-site and mobile MR facilities.
Q: How long does the battery last during MR use?
A: The internal battery provides a minimum of 30 hours of operating life on a full charge, and the unit runs on battery power only while in MR use.
Q: How much monitoring data can the 7500FO store?
A: The monitor holds approximately 70 hours of data assuming continuous operation, giving facilities flexibility in when they offload monitoring records.
Q: What does the Pulse Quality Indicator do?
A: It detects patient movement or signal quality changes that may require the sensor site to be stabilized or repositioned, helping clinicians maintain accurate readings.
Q: What warranty comes with the 7500FO?
A: The Nonin Model 7500FO ships with a 3-year manufacturer warranty.
