For any hospital procurement director, confirming a device is "FDA-approved" is a critical, non-negotiable step in the evaluation process. However, in the world of pulse oximetry, the definition of excellence is evolving. The U.S. Food and Drug Administration (FDA) is signaling that basic clearance is no longer the only benchmark for quality, particularly concerning the device's accuracy across diverse patient populations .
This technical deep dive provides a high-level overview of these critical regulatory developments to help you make more informed, future-proof procurement decisions.
An Expert's Perspective: The Evolving Definition of Clinical Accuracy
"For years, top-tier engineering teams have understood that true clinical accuracy means accuracy for every patient. The challenge of ensuring consistent performance across different skin pigmentations is a complex issue of physics and signal processing. The FDA's new focus validates this priority and raises the bar for the entire industry. It's a move that separates manufacturers who simply meet the minimum standard from those who are truly committed to equitable healthcare."

A Technical Deep Dive: Understanding the FDA's January 2025 Draft Guidance
In January 2025, the FDA issued new draft guidance that will change how medical-grade pulse oximeters are tested and evaluated . After holding two advisory committee meetings and partnering with academic institutions on new clinical studies, the agency has proposed updated recommendations to address long-standing concerns about whether oximeter accuracy is affected by a person's skin pigmentation .
Key takeaways from this development include:
-
A Higher Bar for Testing: The guidance provides new recommendations for how manufacturers should conduct non-clinical and clinical performance testing to support their premarket submissions, with a focus on ensuring performance across a diverse range of skin tones .
-
Increased Transparency: The FDA has proposed creating a publicly available webpage that will identify all FDA-cleared oximeters that have demonstrated comparable performance across skin pigmentations through rigorous data review . This will give procurement directors an invaluable tool for vetting manufacturer claims.
The Procurement Framework: Basic Compliance vs. Future-Ready Performance
This shift creates a clear distinction between manufacturers who meet the baseline and those who are engineered for excellence.

|
Views FDA clearance as the finish line.
|
Views FDA guidance as a minimum standard and actively engineers to exceed it.
|
|
Clinical Validation
|
Relies solely on data submitted for initial clearance.
|
Proactively validates performance against higher international standards like ISO 80601-2-61.
|
|
Technical Features
|
Provides basic SpO2 and pulse rate.
|
Includes advanced features like a Perfusion Index (PI) to help clinicians assess signal quality in all patients.
|
|
Quality System
|
Has a basic quality system in place.
|
Operates under a rigorous, audited ISO 13485 certified Quality Management System.

A Future-Proof Procurement Checklist for Pulse Oximeters
As you prepare your next RFQ, use this checklist to ensure you are selecting a partner aligned with the future of regulatory standards:
-
Ask About Skin Tone Data: Can the manufacturer provide specific data demonstrating their device's performance across a range of skin pigmentations, in line with the FDA's new focus?
-
Verify ISO Compliance: Does the device comply with the specific international standard for pulse oximeters, ISO 80601-2-61, which indicates a higher level of performance testing?
-
Demand Clinical-Grade Features: Does the device include a Perfusion Index (PI) to help clinicians validate the quality of their readings in challenging situations?
-
Audit the Quality System: Is the manufacturer's facility ISO 13485 certified? This is a key indicator of their commitment to quality control and their ability to meet evolving regulatory demands.
-
Inquire About Long-Term Reliability: What is the device's documented defect rate and warranty term? A long warranty (like VistaMed's 5-Year Standard Warranty) is a sign of a manufacturer's confidence in their engineering.
Conclusion: Partnering with the Future in Mind
The FDA's new guidance on pulse oximeters is a clear signal: the standard for excellence is rising. "FDA-approved" is simply the entry ticket. The most strategic and lowest-risk procurement decision is to partner with a manufacturer who has a documented history of quality, a proactive approach to clinical validation, and an engineering philosophy that is already aligned with the future of regulatory expectations.
