Clinical operations note: what-is-fluoroscopy-a-quality-inspectors-take-on-globus-medical-defibrillator-aeds-115

A Tuesday morning call in March 2024 started with a simple question: “So is this defibrillator AED something your team can certify, like the spine implants?”

The woman on the other end was a hospital supply coordinator. She was building a pre-op lounge and wanted an AED on the wall. I had to explain that my job at Globus Medical isn’t to certify third-party AEDs. But her question stayed with me, because it’s the same confusion I see over and over. People lump every medical device into one category, and that gets expensive.

The background nobody sees

I’m a quality and compliance manager at Globus Medical. For the past four-plus years, I’ve reviewed product documentation, supplier specs, and packaging claims before anything reaches a customer. It’s roughly 200 items a year. In Q1 2024, I rejected 8% of first deliveries because of labeling inconsistencies—usually the kind of thing a surgeon wouldn’t catch but an auditor would.

From the outside, it looks like my job is checking boxes. The reality is different: most of my work is translation. I translate engineer-speak into clinical language, and clinical language into procurement language. That’s why the AED question didn’t annoy me. It made me think about a lesson I learned the hard way.

My first nebulizer machine purchase (and the mistake that followed)

Before I joined Globus Medical, I worked at a regional surgery center. We were opening a new wing, which sounds exciting until you realize it’s just a lot of spreadsheets. The center director asked me to order “a nebulizer machine” and “a defibrillator AED.” He said it casually, like both were similar.

I knew the basics, but in my first year I made the classic quality mistake: I approved a supplier’s nebulizer documentation because the box said “medical device.” I didn’t check the package insert for particle size or drug compatibility. A respiratory therapist caught it two days later. She asked, “What’s the MMAD?” I had no idea. (MMAD is mass median aerodynamic diameter—basically how much of the medication reaches the lungs.) The device wasn’t wrong, but my approval process was incomplete.

That was the first time I understood the gap between “looks like a device” and “works for the patient.”

A nebulizer machine turns liquid medication into a fine mist for breathing treatments. A defibrillator AED analyzes heart rhythm and, if needed, delivers a shock to restore a normal rhythm. They both have screens and buttons. They are not related.

Separately, I once skipped a battery-life check on an AED because the brochure said “long life.” I thought, what are the odds? The unit beeped low battery during staff training. It wasn’t a patient emergency, but it broke my confidence in that vendor. “Long life” is not a specification.

What is fluoroscopy? The question that surprised me

In September 2024, a newly hired purchasing agent at a hospital asked me, “What is fluoroscopy? Is it just X-ray with more steps?”

That’s actually a fair question. Fluoroscopy is real-time X-ray. A single X-ray is a snapshot; fluoroscopy is a live video. In spine surgery, a C-arm provides continuous images so the surgeon can see the position of an instrument while it moves. It’s not the same as a CT scan or MRI. It uses ionizing radiation, but in a dynamic way.

I almost answered with a one-line textbook definition and moved on. Then I remembered the nebulizer story. So instead, I pulled up the imaging screen from our ExcelsiusGPS navigation system and showed her the difference between a static image and a live guided view.

That turned into a 20-minute conversation. We talked about when fluoroscopy is used for screw placement, why surgeons want it, and why hospitals need to train staff on radiation safety. The purchasing agent’s final comment was, “Nobody ever explained it that way.”

That’s the surprise: the technology wasn’t the hard part. It was the vocabulary.

Globus Medical founder and my quality checklist

Globus Medical was founded in 2003 by David Paul, and the early focus was musculoskeletal implants—not a broad conglomerate. That history matters when I review specs. The founder’s emphasis on surgical precision still shows up in how we document products. When I look at a label, I ask: would the first person who touches this understand what it is and what it isn’t?

Before I approve any product documentation, I check the FDA product classification and the intended use statement. That sounds dry, but it catches real mistakes. In 2024, we flagged a brochure that used the term “navigated” on a product that only had clearance for manual use. The surgeon might have caught it, but the label shouldn’t make them do that work.

What I’d tell anyone buying medical equipment

Here’s the lesson I keep relearning:

• Don’t buy a category; buy a function. A nebulizer machine, a defibrillator AED, and a fluoroscopy system all live in a hospital. They do not do the same work.
• Ask what the device measures or delivers. For a nebulizer, that might be particle size. For an AED, it’s the shock protocol and battery replacement. For a C-arm, it’s image clarity and radiation dose.
• Check the documentation like an auditor. If the label doesn’t make sense to the person who will use it, fix it before it reaches the floor.

I’d rather spend ten minutes explaining the difference between fluoroscopy and a static X-ray than deal with mismatched expectations later. An informed customer asks better questions and makes faster decisions.

On that Tuesday call, I did end up helping the supply coordinator, but not by “certifying” the AED. I gave her a short list of questions to ask the AED vendor: battery lifecycle, pad expiration, and whether the unit logs events. She called me back the next day with answers. That’s the kind of quality check I care about—not just paperwork, but shared understanding.

As of January 2025, I’m still getting calls like that one. So if you’ve ever wondered what fluoroscopy is, why a defibrillator AED isn’t a fancy nebulizer machine, or how Globus Medical got started, you’re in good company. I’ve been there. The problem isn’t intelligence. It’s that medical device terminology gets tossed around like everyone already knows it. Nobody does until somebody explains it.
