The Emergency Equipment Checklist I Use for Crash Carts, BiPAPs, and C-Arms

If you run a hospital unit, clinic, or surgery center, this is for you. I'm an emergency equipment coordinator, and I've spent the last nine years building and testing checklists for departments that can't afford downtime.

Here's the thing: a crash cart isn't just a red cart with a defibrillator. A BiPAP isn't a fancy fan. And a C-arm isn't just an X-ray on wheels. They're only useful if they work when you need them. This checklist walks you through six steps to keep them that way.

I've used this exact list during Joint Commission surveys, surprise inspections, and the kind of Tuesday where everything breaks at once. It takes about 30 minutes to run through fully, and it has caught problems that would have turned into disasters.

Step 1: Set the Baseline for Your Crash Cart

Start with the crash cart itself. Most people think “standard crash cart” means one universal setup. That's a legacy idea from the 1980s, when cardiac arrest care was simpler. Today, your cart needs to match your unit's scope: med-surg, ICU, ED, or procedure room.

Your baseline list should cover at least these categories:

• Airway equipment (bag-valve mask, OPA/NPA, ET tubes, backup batteries for laryngoscopes)
• Defibrillator with pads and pediatric doses — yes, check the pad expiry date
• IV access supplies and fluids
• First-line cardiac drugs (epinephrine, amiodarone, etc.)
• Personal protective equipment

I shouldn't have to say this, but I will: check expiry dates monthly. Not quarterly. Not “when someone gets to it.” Monthly.

In March 2024, I found two expired boxes of epinephrine in a crash cart that had been “fully stocked” two weeks earlier. Nobody was using it daily, so the cart looked fine. It wasn't. The expiration check was on the calendar, but the person assigned to it had left for another job, and no one owned it. Classic process failure.

Step 2: Make BiPAP Machines Part of Your Daily Rhythm

BiPAP machines are lifesavers for respiratory distress, but they fail silently if no one checks them. You can't tell by looking at the outside whether the internal pressure sensors are accurate.

Here's what we do every morning in our respiratory-dedicated units:

1. Plug it into a test circuit (or use the factory self-test mode if the model supports it).
2. Verify the pressure readings match the set values. We allow ±1 cm H₂O tolerance.
3. Check the air inlet filter. If it looks gray, replace it. If it looks brown, you've already waited too long.
4. Inspect the circuit and mask for cracks — especially at the humidifier connection. Cracks cause unintentional leaks and patient rebreathing.

One thing people get wrong: they assume if the machine turns on, it's fine. Absolutely not. A BiPAP can power on and still deliver inaccurate pressures, which is worse than no therapy because it gives a false sense of treatment.

Last quarter, I caught a BiPAP during a weekly test that was delivering 14 cm H₂O when set to 20. The internal pressure sensor had drifted. It had passed the “does it power up” check for two weeks straight. The patient impact would have been significant — but we caught it because we did the full test, not the lazy version.

Step 3: Understand How a C-Arm Works (So You Can Spot Problems)

You don't need to be a radiologist to run a C-arm, but you do need to understand the basics to check it properly.

A C-arm is a mobile X-ray machine. “C” comes from the C-shaped arm that holds the X-ray tube on one end and the detector on the other. The patient lies in the gap, and the arm rotates around them to get different angles. The X-ray tube emits radiation through the patient, and the detector on the opposite side captures the image.

Two common types of detectors:

• Image intensifier — older, bulky, can become blurry over time
• Flat panel detector — newer, clearer, more expensive to replace

When you're doing a pre-case checklist, you're checking for three things:

• Does the X-ray arm move smoothly and lock in position?
• Does the image appear without distortion or sudden brightness drops?
• Does the collimation work? (If you can't narrow the field, you're delivering unnecessary radiation.)

A distorted image on a C-arm is not a technical nuisance — it can lead to wrong screw placement in spine cases. That's a risk you can't take.

Step 4: Build a Realistic Inspection Schedule

Here's the schedule that has worked across multiple facilities I've coordinated:

• Daily: Crash cart seal check, defibrillator battery charge, BiPAP visual inspection
• Weekly: BiPAP functional test, C-arm position lock test
• Monthly: Drug expiry review, C-arm detector cleanliness, backup battery test

People often think weekly checks are overkill. They're not. A weekly functional test takes 10 minutes and catches issues like the BiPAP pressure drift I mentioned. Monthly is too late for a machine that gets used twice a week.

Also: don't blindly trust the manufacturer's recommended frequency. One brand's BiPAP self-test takes 6 minutes; another's takes 20. Align your schedule with your device's specific self-test feature, but still add a manual circuit check.

Step 5: Use the Envista Portal for Documentation and Updates

This is the step most people skip, and it's exactly where Envista login comes in. If your facility uses Envista equipment — imaging systems, diagnostic tools, surgical instruments — you need a working Envista portal login.

Why? Because that's where the manufacturer stores updated service manuals, software patches, and safety notices. If you're only working off the paper binder that came with the device, you're probably operating on outdated information.

I remember a few years ago, one of our imaging systems had a known software bug that affected image quality at certain exposure levels. The fix was posted on the Envista portal, but our biomed team hadn't logged in for months. We only discovered the issue during a particularly bad case image review.

If you're not sure whether your team has portal access, that's your first action item. The login is usually tied to your account administrator, and it takes about 15 minutes to set up if you have the right email domain.

Once you're in, do this:

• Check for firmware updates on all Envista devices
• Download the latest manuals and store them on an accessible server
• Verify your preventive maintenance schedule matches the current recommendations

The portal is not a nice-to-have. It's the difference between knowing about a recall as soon as it's issued and learning about it from an auditor.

Step 6: Track Issues Instead of Fixing and Forgetting

Most departments keep a paper binder of equipment checks and call it a day. That's fine if you're just trying to pass inspection, but it doesn't help you catch patterns.

I use a shared spreadsheet — nothing fancy — with columns for date, device, issue, action, and time spent. I also add a column for “repeat issue” that I fill in manually if I see the same problem more than twice.

Why does this matter? Because the question isn't whether a BiPAP filter clogged once. It's whether it's the third time this quarter — which tells you the environment is dirtier than expected, or maintenance is cutting corners.

That kind of knowledge eventually becomes your justification for changing service providers, upgrading equipment, or reallocating budget. You won't get approval with “I have a hunch,” but you will with “This specific component has failed five times on the same model in six months.”

One more thing: after any corrective maintenance, run a quick verification test and sign off. Don't close the work order until the equipment is actually proven functional. Seems obvious, but you'd be surprised how many tickets say “fixed” without a test result attached.

Common Mistakes to Avoid

• Worshiping the price tag. Expensive equipment fails too. Just because it was the capital purchase of the year doesn't mean it's immune to sensor drift.
• Letting the busiest person own the checks. If the only person qualified to do the daily BiPAP test is the nurse who's always in the busiest pod, it will get missed. Train two backup people.
• Ignoring the consumables. A C-arm with a cracked image detector is a huge deal, but a crash cart with missing pediatric IV catheters will hurt someone just as badly.
• Not logging in to the vendor portal. This brings me back to Envista login. If you can't access the portal, you lose visibility into recalls and updates. It's a liability, not a convenience issue.

Look, I'm not saying every piece of equipment will fail at the worst possible moment. But in my experience, equipment failures cluster during emergencies when you're stressed and moving fast. That's when you're least likely to notice a subtle pressure drift or a missing consumable.

The fix is boring and simple: a checklist you actually follow, with specific owners, realistic frequency, and documentation that helps you spot trends.

That's the whole thing. Take this list, adapt it to your department, and run it for a month. You'll find small problems while they're still small. And if you're already using Envista equipment but haven't logged into the portal yet — block 15 minutes today and check for updates. Future you will be grateful.
