What is a hybrid operating room? Benefits of a hybrid operating theatre, the hybrid OR equipment list, room size and the special lighting and ceiling coordination it needs.


A **hybrid operating room** brings the angiography suite into the operating theatre. It lets a team place a stent graft, check it with fluoroscopy and open the patient if needed — without moving the patient. It's also the most complex room to plan, especially its ceiling.

> **Definition:** a hybrid OR is an operating theatre with **fixed advanced imaging** (usually a C-arm angiography system) integrated into a fully equipped surgical environment.

## Hybrid operating room benefits

- **One room, one session** for combined endovascular and open procedures.
- **Immediate imaging quality control** before the patient leaves the table.
- **Fewer transfers** between cath lab and OR — safer for unstable patients.
- **Rapid conversion** from minimally invasive to open surgery.
- **Shared use** by vascular, cardiac, neuro, spine, orthopaedic and trauma teams.
- **Research and teaching** through integrated video.

## Hybrid operating room equipment list

| Category | Equipment |
|---|---|
| Imaging | Fixed angiography C-arm (floor or ceiling), sometimes CT-on-rails or MRI |
| Table | Imaging-compatible (radiolucent, floating-top) surgical table |
| Lighting | Dual-head LED surgical lights, endo mode, optional camera |
| Pendants | Anaesthesia and surgical pendants, equipment booms |
| Displays | Large-format monitor on ceiling suspension |
| Radiation protection | Ceiling-suspended lead shields, table skirts, lead walls |
| Anaesthesia & monitoring | Anaesthesia workstation, haemodynamic monitoring |
| Injection | Contrast power injector |
| Integration | Video routing, recording, PACS, telemedicine |
| Support | Perfusion, echocardiography, ESU, suction |

Standard OR items are covered in the [operating room equipment list](https://www.keling-surgicallight.com/blog/operating-room-equipment-list/).

## Room size and layout

- Commonly cited at **roughly 60–80 m² or more**, plus a **control room** and a **technical room** for imaging electronics.
- Reinforced floors or ceilings for the imaging gantry.
- Radiation shielding in walls, doors and windows.
- Positions of the C-arm in park, working and transfer positions dictate where everything else goes.

General principles are in [operating room layout and design](https://www.keling-surgicallight.com/blog/operating-room-layout-design/).

## Lighting a hybrid OR

Lighting is harder here than in any other theatre:

1. **Collision zones** — the ceiling C-arm or its rails, the display boom and radiation shields all travel through the space the light arms need. The light's central axis is usually placed outside the imaging rail field, with long arms.
2. **Two heads** from different directions are essential when an imaging detector occupies one side of the table. Options: [KL-LED-DT6I](https://www.keling-surgicallight.com/products/kl-led-dt6i-double-dome-led-shadowless-operating-lamp/) or [KL-LED-DTR78](https://www.keling-surgicallight.com/products/kl-led-dtr78-double-dome-led-shadowless-operating-lamp-camera/), 160,000 lux per dome.
3. **Endo / ambient mode** — during fluoroscopy the surgical light is reduced (10,000–15,000 lux on Keling LED lights) so displays stay readable.
4. **Camera integration** — a light-head camera records the open part of the procedure alongside imaging. See the [STR78 / DTR78 4K camera system](https://www.keling-surgicallight.com/products/kl-led-str78-dtr78-camera-system-led-surgical-light/) and [surgical camera vs endoscopy camera](https://www.keling-surgicallight.com/blog/surgical-camera-vs-endoscopy-camera/).
5. **Colour rendering** — high R9 helps when switching between screen and wound.

## Planning steps

1. Choose the imaging system first; obtain the vendor's planning drawings.
2. Draw the ceiling coordination plan: imaging rails, light axis, pendants, display boom, shields, airflow canopy.
3. Simulate arm reach and collisions in all working positions.
4. Specify lights, pendants and displays to fit — see [ceiling surgical light installation](https://www.keling-surgicallight.com/blog/ceiling-mounted-surgical-light-installation/).
5. Plan video routing and recording.
6. Commission with all teams present.

## FAQ

### What is a hybrid operating room?

A hybrid operating room is a surgical theatre equipped with fixed, high-quality imaging — usually an angiography C-arm, sometimes CT or MRI — so that open surgery, minimally invasive and image-guided interventions can be performed in the same room and session.

### What are the benefits of a hybrid operating room?

Combined procedures in one session, immediate imaging control of the result, fewer patient transfers, the ability to convert from catheter-based to open surgery instantly, and multidisciplinary use by vascular, cardiac, neuro, orthopaedic and trauma teams.

### What equipment is in a hybrid operating room?

A fixed imaging system (angiography C-arm, CT or MRI), an imaging-compatible surgical table, ceiling surgical lights and pendants, large-format displays, radiation protection, anaesthesia and monitoring, contrast injector, video integration and often a surgical light camera.

### How big is a hybrid operating room?

Hybrid ORs are much larger than standard ORs — commonly cited at roughly 60–80 m² or more, plus a control room and technical room. The imaging vendor's planning guide defines the actual requirement.

### What lighting does a hybrid OR need?

Dual-head LED surgical lights on a ceiling axis positioned to avoid the imaging system's travel paths, an endo/ambient mode for fluoroscopy, display-friendly ambient lighting and optionally a camera for documentation.
