The Medical-Supply Jargon Buster: Plain-English Glossary
Every confusing word on the box, the spec sheet, or the doctor's note — translated into one warm, everyday sentence. No jargon, promise. Just the plain meaning, plus where you'll bump into each word in real life.
The label says "hydrocolloid." You just want to know what it does.
When you're suddenly caring for someone at home, the words come at you fast. They're printed on the packaging, scribbled on the discharge sheet, and rattled off at the pharmacy counter — and nobody stops to explain them.
That's what this glossary is for. We've collected the words that trip people up most and given each one a single, friendly sentence. No medical degree required. When a term shows up on a specific piece of gear, we point you to the device guide where it actually matters, so the word finally makes sense in context.
The plain-English glossary
Eight of the words readers ask about most. Each one is explained the way you'd want a kind friend to explain it — then a note on where you'll see it.
- Hydrocolloid
- A bandage that turns into a soft gel cushion once it touches the skin, keeping a wound moist and protected so it can heal in peace. Where you'll see this word: on dressing boxes in the first-aid aisle — more in our home medical devices guide.
- Antimicrobial
- A coating or material that quietly discourages germs from settling and multiplying on a surface, like a dressing or a wound pad. Where you'll see this word: on bandages and cleaning supplies — explained in Explained Simply.
- Systolic
- The top number on a blood-pressure reading — the pressure in the moment your heart gives a beat (a squeeze). Where you'll see this word: on the screen of a home blood-pressure monitor — walked through in our caregiver manual.
- SpO2
- A friendly shorthand for how much oxygen your blood is carrying, shown as a percentage — the number that little fingertip clip lights up. Where you'll see this word: on a pulse oximeter — see the caregiver manual.
- cmH2O
- The gentle unit a CPAP uses to measure how softly it pushes air — think of it as how firm or feather-light the airflow feels. Where you'll see this word: on a CPAP machine's pressure setting — decoded in our CPAP guide for non-experts.
- AHI
- A nightly score that counts how many times breathing paused or got shallow while someone slept — lower means a calmer night. Where you'll see this word: on a CPAP report or sleep summary — explained in the CPAP guide.
- Bariatric
- Simply means "built sturdier and roomier" — gear designed to safely support a larger body with extra strength and width. Where you'll see this word: on lifts, slings, and beds — covered in our patient-lift sling guide.
- Trapeze bar
- A handle that hangs above the bed like a swing's grip, giving someone something to pull on so they can shift or sit up on their own. Where you'll see this word: around hospital-style beds — see safe transfers at home.
How to use this glossary
Three relaxed ways to get the most out of it.
Look up the word in front of you
Spot the term on a box, a screen, or a note? Find it above and read the one-sentence meaning. That's usually all you need to feel steady again.
Follow the link to the gear
Each term tells you where you'll see it and links to the Device Decoder for that piece of equipment — so the word makes sense alongside the thing it describes.
Keep it handy for next time
Bookmark this page. New words tend to show up over weeks, not all at once, and it helps to have a calm place to come back to.

Please do. This glossary grows from real questions. Drop your term in our community <a href="/forum">forum</a> and we'll add it in plain English, along with a note on where you'll run into it.
Is this medical advice?
No — it's plain-language education only. We translate the words so you can talk to your doctor, nurse, or pharmacist with confidence. They're always the right people for advice about a specific person's care.
