CAM-129
Where is the crash cart?
A unit hallway. The kit lives against the wall, but the crash cart isn’t there: with its colored drawers and the defibrillator on top, it’s been left standing in the middle of the passage, in front of the double doors. On the left, a supply cart with labeled compartments, a monitor on a wheeled stand and a free stretcher with a blue mattress. On the right, a rolling rack with sterile supplies stacked on it. In the middle, a professional in scrubs is checking something on a clipboard. At the back, more carts and someone walking away. This camera doesn’t look at people: it looks at equipment, and says whether it’s where the hospital said it should be.

The rule
You decide once. IRIS applies it always.
If
the slot where a piece of equipment belongs stays empty for longer than the unit has set
Then
- show in the unit’s status what is missing and since when
- say which camera last saw the equipment
- close the alert only when the equipment is back in its slot
The instruction that set it up«Tell me whether the crash cart is in its slot, and let me know when it has been out of it for a while.»
What changes
What changes for whoever runs the unit
Hospital kit spends half its life lost. A portable ultrasound, an infusion pump or a crash cart get borrowed between units, left in a hallway and turn up three hours later in another department. That never shows up in an incident log, but it’s paid for twice: in nursing minutes spent looking, and in machines bought again because the first one can’t be found. Here IRIS watches nobody: it looks at a slot in the hallway and says whether the cart is in it. When it isn’t, it says since when and which camera last saw it, and somebody goes and fetches it. It’s the dullest thing IRIS does in a hospital, and probably the thing that will get used the most.
What people usually ask
Does IRIS know who took the equipment?
No, and it doesn’t even look. IRIS does not identify anyone: it does not recognize faces, it does not know who any professional or patient is, it keeps no file on anyone and it has no access to medical records. What it sees is the equipment: whether it’s in its slot or not. Who moved it appears nowhere, because the camera doesn’t know and there’s no way to ask it. And for what’s needed here — finding the cart — knowing that isn’t needed at all.
Does every piece of equipment need a tag?
No. There’s no chip here, no sticker, no battery to change: the camera sees the shape of the equipment in the place, the same way it sees a stretcher or a wheelchair. That has a limit and it has to be said: it tells one type of equipment apart, it doesn’t tell two identical carts apart. To know whether there’s a crash cart in this slot, that’s enough; to know exactly which of the hospital’s carts it is, it isn’t.
What if the cart is out because it’s being used?
Then it’s right that it isn’t there, and the rule is written with that in mind. The hospital decides how many minutes an empty slot is tolerated, in which bands and in which places. The camera doesn’t know whether the cart is in use: it knows the slot has been without it for twenty-two minutes. Whether that’s normal or someone should go and fetch it is decided by the person reading it, which is why the figure appears in the unit’s status and not as an alarm that rings. There’s nothing to attend to here: there’s something to look up.

Malls
What does a mall see beyond the visitor count?
12 cases: 4 raise an alert when something happens and 8 only measure. You see each image as it is, and then with what IRIS understands on top.
Airports
What does an airport see before the line forms?
14 cases: 7 raise an alert when something happens and 7 only measure. You see each image as it is, and then with what IRIS understands on top.
And the best part
“The white van, Tuesday afternoon.”That’s enough to find it.
You type it the way you’d tell a colleague, and the matching minutes come back, each with its camera and its time. You don’t need to remember the exact moment.
Tell us your problem and we’ll say whether IRIS understands it, or not yet.
