7 Things Paramedics Wish Everyone On A Blood Thinner Knew Before Winter

(#6 is why my own mother wears one, and why I bought my father-in-law the black one)
Every winter the calls change. Icy steps. Christmas lights. A strange bathroom at the kids' house. After 24 years on the ambulance, here's what I see when I get there, and the one thing I make the people I love put on before the first freeze.

Ambulance lights on an icy driveway at night, a dropped snow shovel
Lake-effect season in Erie. Most of my winter calls start on a driveway like this one.

I've knelt on more icy driveways than I can count.

Twenty-four winters on an ambulance in Erie, Pennsylvania will do that. Lake-effect snow. Black ice before the salt trucks get out. Porch steps that look dry and aren't.

So here's something you might not expect a medic to say:

The patients who scare me aren't the ones who look bad.

They're the ones on a blood thinner who look fine. Sitting up. Talking. Apologizing for the fuss. Telling me they're OK.

When you started that pill, somebody handed you a bottle and a printout. Nobody sat you down and explained what changes for the people who come to help you when something goes wrong.

So I will. Seven things. Every one of them comes from a real call.

Read this before you need it. And if you only read one, read #6.

#1: "My hands are on your wrist before I know your name."

When I get to you, one of the first things I do is check your pulse.

And the pulse is right there on your wrist. Before I've asked your name, before anybody's found your purse, before anyone's told me a thing, my fingers are already on that spot.

So whatever is on that wrist gets read in the first seconds. Anything anywhere else has to wait. (#3 and #4 will show you just how long.)

Mrs. K's wrist on Christmas Eve: a little gold watch, her rings, and nothing that could tell me what was in her blood.

Christmas Eve, a few years back. A woman I'll call Mrs. K, 81, at the bottom of her basement stairs. She'd gone down for a roasting pan.

On her wrist: a little gold watch. Her late husband's ring on the hand beside it. Things that meant the world to her.

And not one thing that told me what was in her blood.

She kept saying, "I'm fine, honey, I just slipped." Hold on to that sentence. I'll come back to why it makes my stomach drop.

"The paramedic read it out loud before I could even speak."

I felt the world tilt in the garden. Next thing, a young medic was reading my wrist aloud to his partner. No guessing, no delay.

#2: On a blood thinner, a little fall isn't little.

Your blood doesn't clot the way it used to. That's not a side effect. That's the whole point of the pill. It's protecting you from a clot or a stroke, and you need it.

But it changes what a fall means.

It's why a cabinet door leaves a purple mark that won't quit. It's why a paper cut keeps going.

A cabinet door did this. On a blood thinner the body doesn't seal small bleeds the way it used to.

And it's why a bump to the head is a different call for us. On a blood thinner, a bleed inside the head can build slowly, while you feel fine and keep talking to me.

That's why the guidance that comes with these medicines says the same thing: after a fall or any real hit to the head, get checked. Even if you feel OK.

The Saturday after Thanksgiving last year, 2:10 in the afternoon, a 74-year-old man I'll call Bud was eight feet up a ladder in Millcreek, hanging icicle lights. The foot of the ladder was on a strip of driveway that had been ice since sunrise.

The ladder skated out. Bud came down sideways and caught the side of his head on the porch rail. A neighbor rolling his trash can to the curb called 911.

When we pulled up, Bud was sitting on his own frozen lawn, holding a strand of lights. Awake. Talking. Annoyed.

"I'm fine. I've got two strands left."

I asked if his heart pill was a blood thinner. He looked at me like I'd asked his shoe size. "Could be. My wife does the pills."

His wife was at the mall with the grandkids. So my partner Tony went inside and opened kitchen cabinets in a stranger's house until he found the bottle, behind the coffee filters. Blood thinner.

The scan found a small bleed. They caught it. Four nights in the hospital instead of on his ladder. The week before Christmas a card came to the station, addressed to "The two guys who wouldn't let me finish my lights."

Happy ending. But think about how long it took us to learn one word.

#3: Your wallet card is in your purse. Your purse is on the kitchen chair.

Good, careful people do the responsible thing. They write their medications on a card and keep it in their wallet.

Now picture where that wallet actually is when I get to you.

When you fall, the card doesn't fall with you.

It's in the purse hanging on the kitchen chair. In the coat on the hook. In the car in the driveway.

Everything the ER needs to know, written down neatly. One floor away from the person who needs it.

And here's what nobody tells you: we treat the person on the floor. We don't go through your belongings at the scene. Your purse usually gets opened later, at the hospital, by somebody else.

Mrs. K had a card. A good one, neatly written.

It was in her purse. Upstairs. On a kitchen chair.

And even when the card turns up, it's often out of date. Doctors switch blood thinners. People get moved from one pill to another. How many go back and rewrite the card? Not many.

"It sat in a drawer for three months because I did not want a medical bracelet."

My sister gave it to me and I put it away. What changed my mind was a woman at church asking where I got my bracelet. Not my medical bracelet. My bracelet. It has not been off since.

#4: "I'm not going to unlock your phone."

"It's all in my phone." I hear that one a lot.

Here's where your phone is when I find you. Locked. In the other room. On the charger. Under you. In the snow three feet away, screen cracked.

Phones fall too. This one spent twenty minutes face down on a porch step.

Yes, phones can show a medical screen without the passcode, if somebody set it up, and if somebody thinks to look.

But picture me on an icy driveway at night, gloves on, with your head in my partner's hands. Nobody is going hunting through a stranger's phone.

Tony, my partner on the rig, puts it best: "The phone is for calling us. It's not for talking to us."

#5: Even if you can talk, you might not say it. And if you live alone, nobody says it for you.

This one surprises families the most.

You'd think if a person is awake and talking, they'll just tell us. Here's what really happens.

Shock. A knock to the head. Hearing aids still on the nightstand. Cold, scared, embarrassed, with a neighbor standing over you.

I've had people tell me their full name, their birthday and their dog's name… and forget the pill they've taken every single day for years.

"The little one. For my heart."

That's the answer I get. Every week.

And if you live alone? Your husband's at the store. Your kids are 900 miles away. There's nobody standing in the kitchen to say, "She's on a blood thinner."

Bud told us he was fine. Mrs. K told us she was fine. Both of them meant it. And Bud's answer is the one I hear most: "My wife does the pills."

"I'm fine" is the most dangerous sentence I hear all winter.

"The ER nurse spotted it in seconds."

I collapsed at the grocery store. The paramedics saw the bracelet, read my medication, and treated me correctly right away.

#6: The ER needs to know WHICH blood thinner. That's why my mother wears this.

Here's the part I wish every patient understood.

At the hospital, they don't handle every blood thinner the same way. Eliquis, Xarelto, warfarin: different drugs, different tools to reverse them.

So if you hit your head, the faster the ER knows you're on one, and the more exactly they know which one, the faster they can make the right move.

That is not something I'm willing to leave to a card in a purse, a locked phone, or a scared 77-year-old trying to remember a name.

Because my mother, Theresa, is 77. Widow. Lives alone on West 26th Street. On a blood thinner for AFib. Bingo at the parish hall every Wednesday. And she'd rather eat glass than wear anything that looks like a hospital tag.

So I went looking for something she'd actually keep on. Not a rubber hospital band. Not a pendant that needs charging. Not one more monthly-fee button that only works if you're awake to press it.

What I found is the Onuva Blood Thinner Bracelet.

My father-in-law, Bill Novak, is 81. Retired steelworker. Still shovels his own walk. Told me flat out he "doesn't wear jewelry."

He got the black silicone band. Turned it over in his hands for a long time and said, "Looks like a watch band. Fine." It's on his wrist when he shovels. I checked.

You pick the engraving:

✔ BLOOD THINNER: stays right even if your doctor switches you to a different one.

✔ Or the exact drug: ELIQUIS, XARELTO or WARFARIN, so the ER knows exactly which one.

What I look for as a medic, and why this one passes:

#7: Winter is when I see it.

Every year it's the same list.

Black ice before the salt goes down. Dark by 5 o'clock. Ladders and Christmas lights. Shoveling the end of the driveway the plow just buried. Stairs and bathrooms at somebody else's house over the holidays, at night, in socks.

And everybody's distracted.

A ladder against a snowy gutter with icicle lights half hung and one strand dangling
Half-hung lights, a ladder on frozen ground. I could drive to this call with my eyes closed.

The CDC says about 1 in 4 adults 65 and older falls every year. Winter just stacks the deck.

Bud had two strands left. Mrs. K just wanted the roasting pan.

So here's my one ask.

If you do one thing before the first freeze, put it on your wrist.

And if your mom or dad is on a blood thinner, put it on theirs at Thanksgiving, while everybody's in one room and nobody can say "I'll do it later."

Right now there's a holiday deal on that makes it easy to get one for you and one for someone you love. Order early, so it's on their wrist before the holidays, not wrapped under a tree while the ice is already out there.

You've got two choices

What Families Ask Me

Which engraving should I pick?

If you're not sure, pick BLOOD THINNER. It stays right even if your doctor switches you to a different one. If you want the ER to know the exact drug at a glance, pick ELIQUIS, XARELTO or WARFARIN. One word per bracelet.

What if my doctor switches me?

That's exactly why most people choose BLOOD THINNER. It's true no matter which blood thinner you're on, so it never goes out of date the way a wallet card does.

Will it fit?

Both styles adjust. The steel chain has an extender, and the silicone band buckles like a watch strap. They fit wrists from 5.5" to 8".

Can I wear it every day?

That's the whole idea. Stainless steel or silicone, nothing to charge, nothing to switch on. Put it on and leave it on.

Does it call anyone or track me?

No. It's an engraved bracelet: no GPS, no alerts, no battery, no subscription. Its one job is to tell whoever finds you, in big clear letters, what's in your blood.

What if I lose it?

Lost or broken in the first year, Onuva replaces it free.

Can I send it back?

Yes. You have 90 days. If it isn't right, you get your money back.
