Why “It Meets Spec” Isn’t Good Enough: A Quality Manager’s View on Medical Device Procurement

For the past four years, I’ve been the person who signs off on medical equipment before it reaches our clinicians. Roughly 200+ unique items a year cross my desk—CPAP machines, transfer lifts, emergency response equipment, you name it. And if there’s one sentence that makes my eye twitch, it’s this: “It meets spec.”

I’m not saying manufacturers are deliberately misleading anyone. But I’ve learned—the hard way—that spec compliance and real-world readiness are two very different things. The gap between them has cost us time, money, and at least one very uncomfortable conversation with an angry department head.

Here’s the thing about medical equipment: the cost of a spec gap isn’t a return shipment or a credit memo. It’s a patient whose therapy stops at 2 a.m. It’s a staff member who injures their back because a lift didn’t fit the room. It’s a response delay on a code blue because the AED was in the wrong spot. Those costs don’t show up on a purchase order.

The ResMed 10 battery backup that wasn’t

Take something as seemingly straightforward as backup power. Our respiratory care unit runs about 30 ResMed 10 devices. During a planned utility shutdown in early 2023, I approved an eight-hour battery backup requirement. The vendor confirmed it: “Eight hours, no problem.”

Except—and this is where I kick myself—we never defined what “eight hours” actually meant. Did it mean continuous therapy at the patient’s prescribed pressure, heated humidifier running? Or did it mean minimum settings, room temperature, best-case conditions? The vendor assumed one thing. I assumed another. We found out the difference during a real power incident, when a patient’s device cut out four hours and twenty minutes into an overnight outage. In a sleep lab. With patients who’d been told the system could handle it.

I said “we need it to last through a typical outage.” They heard “run time under ideal conditions.” Result: a gap that only surfaced at the worst possible moment.

To be fair to the vendor, they offered to upgrade the batteries at their cost. But that didn’t un-run the outage, and it didn’t rebuild the patients’ confidence. Now every battery backup spec we write includes the phrase “at prescribed settings.” And the first unit off the truck gets a full discharge test. It takes about ten hours of watching a device run. It’s boring. But it has caught two underperforming units since we started.

The ResMed foam mask and the “standard” problem

The second lesson came from something far simpler: foam. We started evaluating ResMed foam mask options because patients with sensitive skin were struggling with silicone-only seals. A clinician asked the rep a reasonable question: “Is the foam recyclable?”

“Absolutely,” the rep said.

Technically? Maybe. Practically? Almost certainly not in a hospital waste stream. Per FTC guidelines (ftc.gov), a product can be advertised as recyclable only if recycling facilities are available to at least 60% of consumers where the product is sold. The foam might qualify in some markets. But clinical waste typically goes through sterilization first, then gets incinerated or landfilled. The material never reaches a recycling facility, no matter what the label suggests.

FTC’s Business Guidance on Advertising is pretty clear on this: claims must be truthful, not misleading, and substantiated. I doubt the rep intended to deceive anyone. But the claim was misleading in context—and that distinction matters when you’re making purchasing decisions based on stated values.

The bigger issue, though, was the word “standard.” USPS defines a standard envelope with absolute precision: a minimum of 3.5 by 5 inches, a maximum of 6.125 by 11.5 inches, thickness capped at a quarter inch. No ambiguity. Medical equipment? A “medium” full-face mask from one manufacturer can fit nothing like a “medium” from another. “Standard” can mean “the size we’ve always made,” “the size most customers order,” or “the size our demo face model happens to wear.” None of those are wrong. None of them are interchangeable.

That’s not a manufacturing defect. It’s a vocabulary problem. And the only fix is asking clarifying questions until every stakeholder in the room is describing the same object.

Patient transfer devices, AEDs, and the same pattern

ResMed isn’t the only place I’ve seen this. We’ve purchased patient transfer devices—patient lifts, slings, all of that—with weight capacities that checked every box on the requirement sheet. But stamped capacity isn’t the same as usable capability. Our first lift had the right rating and still couldn’t maneuver our smaller exam rooms without scraping door frames. Specs confirmed, signed, delivered. What we hadn’t run was a simple test through an actual doorway.

“How to use a patient lift” gets treated as a training question. In my experience, it’s a design question first. If the equipment doesn’t fit the space, no amount of staff training fixes it.

Sling sizing gave us the same headache. We ordered “standard adult” slings, but the “standard adult” width in the catalog didn’t match the bariatric-capable lift we paired with them. The mismatch was caught during a dry fit, fortunately, not with a patient in the sling.

Same story with our defibrillator AED placement. We met every regulatory requirement for the device itself: correct model, maintenance schedule, trained clinical staff. But the initial location was far enough from one end of the clinic that the average response time exceeded any reasonable standard. Compliance-wise, everything was fine. Life-safety-wise, it wasn’t.

Even after we approved the replacement lift, I kept second-guessing. What if the new model had a similar clearance problem somewhere unexpected? The six weeks between ordering and delivery were tense. I didn’t relax until the unit rolled through the first doorway without a scrape.

The most frustrating part of all this: the same pattern keeps recurring despite clear communication. You’d think a written spec would prevent misunderstandings. It doesn’t. Interpretation varies wildly between engineering teams, sales reps, and facility managers. We all said the same words, meant different things, and found out when the equipment was already in service.

Before you say “we have strict procurement”

I can already hear someone with a well-managed purchasing department pushing back: “We have detailed specifications. Our vendors are pre-qualified. We don’t see these problems.”

Good—honestly. But I’d still ask when someone last ran a physical performance verification on one of those compliant products. Not a visual inspection. An actual test, under conditions that match the facility.

The industry is changing. What passed as thorough verification in 2020 carries less weight in 2025. Battery chemistry, material science, device software—everything evolves faster than the assumption that the spec sheet tells the whole story.

A tiny example: USPS bumped First-Class postage to $0.73 an ounce in January 2025. That change was announced clearly, documented precisely, and understandable to everyone. Medical device procurement rarely gets that level of clarity. And when the cost of being wrong is measured in patient outcomes rather than postage, the margin for error should be smaller, not larger.

What I check before anything reaches a clinician

My process now, in short: know the use case before writing the spec; define what “working” means in that specific context; verify the actual product on arrival with a real test; and document every surprise because that record becomes leverage in the next negotiation. The fundamentals haven’t changed—verify before you trust, test in the environment you’re actually working in. But the execution has transformed.

I no longer accept “it meets spec” at face value. I ask what specifically was tested, under what conditions, and whether that test resembles our facility’s reality. Because at the end of the day, “good enough on paper” isn’t good enough. Not for battery backups. Not for foam masks. Not for patient lifts or defibrillator AED placement. After enough close calls, you start measuring twice.
