The Cable Drawer

Lyrics

Every biomed shop has a cable drawer.

Nobody knows what's at the bottom.

Well, the monitor needs a pulse ox cable,

just a simple little thing.

So I open up the cable drawer

and the whole drawer starts to sing.

There's a lead set from a model that retired long ago.

There's an adapter for an adapter and a coil I'll never know.

I pull on a loop and the rest come up behind

Like a magician's handkerchiefs, the tangled endless kind

Hey! Pull it! Hey! Pull it!

Hey! And out comes more

There's a cable in the drawer for every monitor ever made

Every plug and every pin from every model in the tray

There's a cable in the drawer and it's tangled tight and tight

Every cable in the world except the cable I need tonight

So the student holds the flashlight while we dig down deep inside

We match the part and number to the sheet,

no guessing, that's our pride

We sort them out by type and make and label every bin

We test the keepers, tag the strays,

and toss no guesswork in

And they're at the very bottom,

curled up like a sleeping cat

The pulse ox cable we were after,

well now look at that

Hey, pull it, pull it, there's no more

There's a cable in the drawer for every monitor ever made

Every plug and every pin from every model in the tray

There's a cable in the drawer and it's tangled tight and tight

Every cable in the world except the cable I need tonight

Check the jacket,

check the pins and plug it in just so

The simulator's running and the waveform starts to flow

The nurse gives us a thumbs

up and the monitor's good to go

And we close the drawer real gently, nice and slow

Oh, there's a cable in the drawer for every monitor we've got

Every bin has got a label and the labels hit the spot

There's a cable in the drawer and it's sorted clean and right

Every cable in its bin now and

the cable I need is in sight

Give it a week, it'll be knitting again

The Cable Drawer

Every biomed shop has a cable drawer. A monitor needs a pulse ox cable, and the only way to find the right one is to match it, sort it, label it and test it.

A biomed story song from our shop-floor series. Diagrams are simplified to tell the story; this is not a service procedure, so always follow the manufacturer's instructions and your facility's policy.

The story behind it: Patient monitor accessories (pulse oximetry cables)

Pulse oximetry sensors and the cables that connect them to a monitor are not universal. Each monitor family accepts its own connectors and sensor technology, so a cable that fits the plug is not proof that it will read correctly. Manufacturers publish compatibility lists for their accessories, and those lists are the reference, not the shape of the plug.

That is why the song's fix is a routine, not a lucky find: match the part against the manufacturer's list, sort the drawer by type, label every bin, and check each keeper on a working monitor or a simulator before it goes back to a patient area. Cables that cannot be identified or that fail the check are tagged and set aside rather than returned to the drawer.
