Why the Nonin 7500FO Pulse Oximeter Is a Must for MRI Environments

Magnetic resonance imaging (MRI) environments demand specialized equipment to ensure patient safety and accurate monitoring without interference. The Nonin 7500FO Fiber Optic Pulse Oximeter, available at Turner Medical, is designed specifically for these settings, offering reliable oxygen saturation (SpO2) and pulse rate monitoring. This blog post explores why the Nonin 7500FO is essential for MRI facilities and how it supports clinicians in delivering safe, effective care. Explore our MRI-compatible oximeters to learn more.

The Challenges of Monitoring in MRI Environments

MRI scanners generate powerful magnetic fields (up to 3 Tesla) and radiofrequency (RF) pulses, creating unique challenges for patient monitoring:

• RF Burns: Standard oximeters with metal components can conduct RF energy, risking burns.
• Image Artifacts: Metallic sensors can distort MRI images, compromising diagnostic quality.
• Electromagnetic Interference: Conventional devices may malfunction or produce inaccurate readings in strong magnetic fields.

The Nonin 7500FO addresses these issues with its fiber optic design, ensuring safety and precision in fixed-site or mobile MRI facilities.

Why the Nonin 7500FO Is Ideal for MRI

The Nonin 7500FO is a tabletop pulse oximeter engineered for MRI environments, using fiber optic sensors to eliminate risks associated with traditional oximeters. Key features include:

• Fiber Optic Sensors: Non-conductive 20- or 30-foot cables (e.g., 8000FC for adults, 8000FI for infants) prevent RF burns and image artifacts.


• MR Conditional: Tested for safety at 1.5T and 3T magnetic fields, ensuring reliable performance.


• Versatile Monitoring: Suitable for infant, pediatric, and adult patients, with finger, toe, or ear sensor options like the 8000Q2 ear clip for low-perfusion cases.
• Long Battery Life: Minimum 16-hour runtime with a 4-hour recharge, ideal for extended MRI sessions.


• 70-Hour Memory: Stores SpO2 and pulse rate data for comprehensive patient records.

“The Nonin 7500FO’s fiber optic design gives us peace of mind during MRI scans,” says a radiology technician, praising its reliability. Shop it at Turner Medical’s MRI oximeter collection.

Nonin 7500FO vs. Standard Oximeters

Not all oximeters are safe for MRI environments. Here’s how the Nonin 7500FO compares:

Note: The Nonin 7500FO is MR conditional when used as directed, with the device placed in the control room and fiber optic cables extending into the MRI room.

Why Monitoring Matters in MRI

MRI scans can last from 15 minutes to over an hour, often requiring sedation for infants or anxious patients. Low oxygen saturation (hypoxemia) during scans can lead to serious complications, like organ stress or respiratory failure, if not detected early. The Nonin 7500FO’s real-time monitoring, with audio and visual alarms, empowers clinicians to act quickly. Its PureLight® sensors and pulse quality indicators ensure dependable data, even for poorly perfused patients.
