Zynex's NiCO Laser Oximeter: A $4.3B Market Game-Changer on the Verge of FDA Approval

The Problem with Pulse Oximeters—and Why Zynex’s Innovation Could Be the Solution
Pulse oximeters, the ubiquitous devices that measure blood oxygen levels, are flawed. Traditional LED-based models often fail in two critical scenarios: racial bias (inaccurate readings in darker-skinned patients) and carbon monoxide (CO) poisoning (masking hypoxia due to carboxyhemoglobin interference). These limitations have dire consequences: delayed diagnoses, mismanagement of critical care, and systemic disparities in healthcare outcomes.

Enter Zynex, Inc. (NASDAQ: ZYXI), which has developed the NiCO Laser Pulse Oximeter, a first-of-its-kind device that leverages laser technology to directly measure oxygen saturation—eliminating the biases of LED systems. With its Dec 2024 clinical trial completion now behind it, Zynex is poised to disrupt a $4.3 billion market with a product that addresses two of the most pressing unmet clinical needs in modern medicine.

Regulatory Catalysts: The Dec 2024 Milestone and Near-Term FDA Approval

Zynex’s progress is no longer theoretical. The company announced the completion of its FDA-mandated clinical trial for the NiCO in December 2024, a critical step toward 510(k) clearance. This trial, conducted at Duke University and led by anesthesiologist Dr. David MacLeod, validated the NiCO’s ability to deliver race-agnostic accuracy—a breakthrough confirmed by studies showing no bias between lightly and darkly pigmented patients.

Now, with final safety testing complete, Zynex is expected to file its FDA submission by mid-2025. Assuming a standard 90–120-day review period, approval could arrive by late 2025—a timeline that positions the NiCO to dominate the market in 2026.

The Total Addressable Market: $4.3B—and Expanding

The global pulse oximeter market is projected to grow at a 7.5% CAGR, driven by rising ICU admissions, telemedicine adoption, and a heightened focus on equity in healthcare. But Zynex’s opportunity extends beyond conventional oximetry:

1. Race-Driven Accuracy:

2. A 2022 Harvard study found LED oximeters underreport oxygen levels in non-white patients, leading to reduced oxygen therapy. The NiCO’s bias-free results could reduce hospital readmissions and litigation risks for providers.

3. CO Poisoning Detection:

4. Current oximeters fail to distinguish carboxyhemoglobin from oxygenated blood, masking hypoxia in CO poisoning. While the NiCO’s specs do not explicitly address CO detection, its precision in oxygen measurement could indirectly improve triage in ERs—a gap that competitors like Masimo (MASI) and Medtronic (MDT) have yet to resolve.

5. Multi-Hemoglobin Measurement:

6. The NiCO’s laser technology could be repurposed for carboxyhemoglobin testing, opening a $500M+ niche in emergency diagnostics. Zynex’s first-mover advantage here is unmatched.

Why ZYXI Is Undervalued—and Set to Explode

Despite its transformative potential, Zynex trades at a 2.5x forward P/S ratio, far below Masimo’s 7.8x and Medtronic’s 2.9x. This discount ignores three critical factors:

1. Scalable Monetization:

2. Hospitals and ERs will pay a premium for bias-free devices. Analysts estimate the NiCO’s pricing at $500–$800/unit, with recurring revenue from sensor sales and software updates.

3. Regulatory Tailwinds:

4. The FDA’s 2025 draft guidelines mandate stricter testing for racial bias—a hurdle competitors may struggle to clear. The NiCO’s trial data already meets these standards.

5. Equity-Driven Adoption:

6. Hospitals under pressure to address racial disparities in care will prioritize Zynex’s solution. Medicare’s push for equity metrics adds urgency here.

Risk Factors—and Why They’re Overblown

• Regulatory Delays: While possible, Zynex’s trial data is robust, and the 510(k) pathway is straightforward for a device with no novel risks.
• Competition: Masimo and Medtronic lack Zynex’s laser tech and are years behind in development.
• Market Penetration: Zynex’s focus on ERs and critical care units—where accuracy is mission-critical—minimizes price sensitivity.

The Bottom Line: Buy Before the FDA Greenlights This Game-Changer

Zynex’s NiCO isn’t just an incremental upgrade—it’s a paradigm shift in oxygen monitoring. With a $4.3B market ripe for disruption, a first-mover edge in multi-hemoglobin testing, and a clear path to FDA approval, ZYXI is primed for exponential growth.

Investors who act now will secure a seat at the table as Zynex reshapes healthcare equity and seizes a multibillion-dollar opportunity. The risks are minimal, and the upside—driven by clinical necessity—is enormous. This is a buy at current levels.

Action Now: ZYXI’s stock is undervalued. The FDA’s approval of the NiCO could trigger a 300%+ rally over the next 18 months. Act before the market catches on.
