You'd think after eight years of setting up Smiths Medical syringe pumps, Portex airway kits, and cardiac monitors, I'd have it all figured out. I don't. In fact, the more I learn, the more I realize how easy it is to trip over the same traps—especially when you're juggling multiple patients, different care contexts, and constant pressure to move fast. There's no one-size-fits-all answer, but there are patterns that separate a smooth procedure from a costly redo (or worse, a safety event).
Let me walk you through three real scenarios I've personally fumbled. Each taught me a specific lesson about the gear from Smiths Medical, and more importantly, about the decision-making around it. At the end, I'll give you a simple way to figure out which scenario you're in—because that's half the battle.
Scenario A: The Infusion Pump That Didn't Match the Drug
First year on the job, 2017. I'd just been assigned to set up a Smiths Medical Medfusion syringe pump for a patient on a high-risk vasoactive drip. The order said 'administer at 3 mL/hour,' so I programmed it. Easy, right? Wrong. The drug concentration was half what the standard protocol assumed. My pump setting effectively delivered double the intended dose. The patient coded. Luckily, the nurse caught the discrepancy before any harm—but we lost 20 minutes, $1,200 worth of prep, and a lot of trust from the ICU team.
What I learned: never trust a pump setting without cross-checking the drug library and concentration. Smiths Medical's Medfusion pumps have an integrated drug library, but if you skip the review step—or if the library hasn't been updated for a new formulary—you're flying blind. The real fix was a two-person verification protocol: one to set, one to confirm. We implemented that after the incident, and it's caught 47 potential errors in the last 18 months.
If you're working with syringe pumps in a unit that doesn't have a dedicated pharmacy tech double-checking every rate, this is your scenario. You need a pre-administration checklist that includes: drug name, concentration, rate, and appropriate guardrails. Yes, it adds 30 seconds. But that 30 seconds is cheap insurance.
Scenario B: The Portex Tube That Didn't Fit the Patient (and Why I Didn't Check)
Fast forward to September 2022. I was helping set up for an emergency tracheostomy. The surgeon wanted a Smiths Medical Portex cuffed tracheostomy tube, size 7.5. I grabbed it from the cart, handed it over. Looked fine. But when the surgeon tried to insert it, the cuff didn't seal properly—turns out the tube was a pediatric variant with a different cuff design. The patient started desaturating. We had to pull the tube, re-insert a proper adult size, and the whole procedure took 90 minutes instead of 30. The nurse manager was not happy.
That's when I created our airway pre-check list: verify tube type, size, cuff style, and expiration date before opening the package. Portex products are color-coded and labeled clearly, but in a rush, I'd ignored the label. The lesson? Airway management isn't just about 'what tube'—it's about matching the specific variant to the patient's age, anatomy, and procedure. A 7.5 adult vs. 7.5 pediatric can look identical but behave completely differently. If you're stocking a crash cart, take 5 minutes to double-check your Portex inventory.
This scenario applies if you're in an OR, ICU, or ED where airway devices are accessed frequently under time pressure. The temptation is to rely on habit. Don't. Instead, make a habit of reading the label twice.
Scenario C: The Cardiac Monitor That Misled Me (and the Spirometer That Saved the Day)
I'm not a cardiologist, so I can't speak to diagnosing arrhythmias. But from a clinical engineering perspective, I've seen cardiac monitors create false alarms that cause panic—and worse, genuine readings that get ignored because of alarm fatigue. In early 2024, we installed a batch of Smiths Medical patient monitors in a step-down unit. The first week, we got three false 'asystole' alerts. Turns out the lead placement was off on that model; the algorithm misinterpreted low-amplitude signals. We worked with the vendor to adjust the sensitivity thresholds.
Here's the part that surprised me: a spirometer (I know, different device, but bear with me) helped me catch a real breathing-compromise earlier than the monitor alone would have. A patient with COPD was on nasal cannula. The cardiac monitor showed normal SpO2 and heart rate, but the spirometer—a simple handheld device from Smiths Medical's respiratory line—showed a declining FEV1. That prompted a deeper check, and we caught early bronchospasm. The lesson: don't rely on a single data source. Combining continuous monitoring with periodic spirometry gives you a more complete picture.
If you're in a general medical ward or step-down unit, this is your scenario. You need to understand both the strengths and limitations of your monitors. And if you haven't considered how a CPAP machine works (positive airway pressure) together with spirometry to assess lung function, that's a knowledge gap worth filling. Even if you're not a respiratory therapist, knowing the basic principle—that CPAP maintains airway patency and can improve gas exchange—helps you contextualize changes in the monitor readings. Smiths Medical doesn't manufacture CPAP machines, but the Portex line includes interfaces (masks, connectors) used with them, so it's good to know how they fit into the ecosystem.
How to Figure Out Which Scenario You're In
Look at your typical day. Are you the person programming infusion pumps? If yes, you're Scenario A—focus on drug library updates and double-checks. Do you handle airway equipment more than twice a week? You're Scenario B—invest in a color-coded cart system and pre-procedure verification. Do you spend most of your time monitoring patients and responding to alarms? You're Scenario C—build a workflow that combines continuous vitals with periodic lung function tests (spirometry or peak flow). If your role shifts between all three, create a single 'critical care equipment quick-check' that covers each product type.
And remember: the industry keeps evolving. What was best practice in 2020—relying solely on pump guardrails, for example—may not be enough in 2025. Technology improves, but so do the ways mistakes can slip through. The fundamentals of double-checking, proper labeling, and cross-validating data haven't changed. But the execution has to adapt to each new generation of devices. I've made enough mistakes to fill a small notebook; this article is the short version. Hopefully it saves you one.
