Introduction
Modern gynaecological surgery requires an operating theatre that is carefully planned around surgical workflow, environmental conditions, medical equipment, staff movement, and patient safety. The OT should provide appropriate infrastructure for the procedures performed while allowing the clinical team to work efficiently.
A Gynaec Modular OT With Laminar Airflow is designed by integrating modular wall and ceiling construction with HVAC, HEPA filtration, controlled airflow, pressure management, medical gases, electrical systems, surgical lighting, medical pendants, specialized doors, flooring, and equipment provisions.
The design process should begin with the hospital’s clinical requirements rather than simply selecting an airflow system. The operating table, surgical equipment, staff movement, airflow arrangement, utility connections, and maintenance requirements all need to be coordinated before installation.
How Is a Gynaec Modular OT Designed for Surgery?
The design process normally starts by understanding the clinical activities that will take place inside the theatre. The engineering team then develops the room around the operating table, surgical workflow, equipment, environmental requirements, and infrastructure.
Each part of the OT needs to complement the others.
For example, the laminar airflow arrangement has to be coordinated with surgical lights and medical pendants. Electrical and medical gas outlets need to correspond with equipment positions. Doors and room sealing can also influence pressure relationships.
This is why an integrated design process is important.
1. Start With the Surgical Requirements
The first stage is to identify the procedures the OT will support.
Depending on the hospital’s clinical scope, gynaecology theatres may be used for procedures such as hysterectomy, laparoscopy, hysteroscopy, gynaecological oncology procedures, and other operative interventions.
The project team should understand:
- Procedures to be performed
- Operating table requirements
- Anaesthesia requirements
- Monitoring equipment
- Surgical instruments
- Imaging requirements where applicable
- Staff requirements
- Patient transfer
- Medical gas needs
- Electrical requirements
- Future equipment requirements
This information provides the foundation for the room layout.
2. Conduct a Site Survey
Before detailed design begins, the proposed OT area should be assessed.
The site survey should consider:
- Room dimensions
- Ceiling height
- Structural conditions
- Existing HVAC capacity
- Electrical infrastructure
- Medical gas systems
- Duct routes
- Service shafts
- Access routes
- Existing walls and flooring
- Equipment movement paths
Site assessment is particularly important when an existing room is being renovated.
The engineering team can then design the modular theatre around the actual conditions of the building rather than making assumptions.
3. Plan the Operating Table Position
The operating table is usually one of the main reference points in the OT layout.
The engineering team should establish its position before finalizing the location of other systems.
The design should provide adequate clearance for:
- Surgeons
- Assistants
- Anaesthesia personnel
- Nurses
- Surgical equipment
- Monitoring devices
- Trolleys
- Emergency movement
The table position also influences the laminar airflow area, surgical lighting, medical pendants, medical gas outlets, and electrical points.
4. Design the Airflow Around the Surgical Area
Laminar or unidirectional airflow should be designed around the critical surgical area rather than simply installed as a ceiling feature.
The airflow design may involve:
- AHU
- HEPA filtration
- Supply ductwork
- Ceiling airflow array
- Air-distribution components
- Return-air arrangements
- Pressure management
- Controls
- Air balancing
- Performance testing
The airflow pattern needs to be considered together with the position and dimensions of the operating table.
Altus Airflow describes its laminar airflow systems as integrated with HVAC, HEPA modules, and medical infrastructure for modular OT applications.
5. Integrate HEPA Filtration With HVAC
HEPA filtration is part of the air-management system where high-efficiency filtration is specified.
The design team should consider:

- Airflow volume
- Filter housing
- Sealing
- Pressure drop
- Filter accessibility
- Replacement requirements
- Testing
- Maintenance
HEPA filters should be integrated with the AHU and air-distribution system.
Altus Airflow’s published AHU information describes multistage filtration incorporating pre-, fine-, and HEPA filters, together with temperature, humidity, pressure, and airflow control.
The exact filtration arrangement should be selected according to the hospital’s approved engineering specification.
6. Plan Temperature and Humidity Control
The HVAC system should maintain the environmental conditions specified for the OT.
Temperature and humidity requirements should be established during the design stage and coordinated with:
- AHU capacity
- Airflow volume
- Filtration
- Fresh-air requirements
- Room volume
- Pressure relationships
- Operating schedule
Correct HVAC sizing is important because the system should be capable of achieving the required environmental conditions without being selected independently of the room design.
7. Consider Pressure Management
Room-pressure relationships can form part of the environmental-control strategy.
Where positive pressure is specified, the design should coordinate:
- Supply airflow
- Return or exhaust airflow
- Room sealing
- Door performance
- HVAC controls
- Pressure monitoring
- Air balancing
Pressure performance depends on the complete room and HVAC system rather than a single pressure-control device.
Altus Airflow publishes positive-pressure systems for modular OTs and other controlled healthcare environments.
8. Design Modular Walls Around the Clinical Workflow
The modular walls should be designed around the equipment and services that need to be installed.
Wall planning can include provisions for:
- Electrical outlets
- Medical gas outlets
- Control panels

9. Coordinate the Modular Ceiling
The OT ceiling usually contains several critical systems.
These can include:
- Laminar airflow
- HEPA filtration
- Surgical lights
- Medical pendants
- Access panels
- Electrical services
- Control components
The ceiling should therefore be coordinated before installation.
A change in the position of one ceiling-mounted component can affect the available space for another system. Early coordination helps prevent installation conflicts.
10. Position Surgical Lights Correctly
Surgical lights need to be positioned according to the operating table and expected surgical workflow.
The engineering team should consider the relationship between the lights and:
- Laminar airflow
- HEPA filtration
- Medical pendants
- Ceiling structure
- Operating table
- Surgical team movement
The objective is to provide appropriate illumination while maintaining a well-coordinated ceiling arrangement.
Altus Airflow lists gynaecology and IVF OT surgical lights among its OT equipment offerings.

- Equipment movement
- Surgical workflow
- Ceiling height
- Airflow arrangement
The pendant location should be finalized before completing the ceiling coordination.
12. Plan Medical Gas Connections
Medical gas requirements depend on the hospital’s clinical scope and equipment.
Services may include oxygen, medical air, vacuum, nitrous oxide, and other specified gases.
The engineering design should determine:
- Outlet quantity
- Outlet locations
- Pipeline routes
- Isolation systems
- Alarm arrangements
- Equipment connections
- Testing requirements
Medical gas outlets should be accessible and positioned according to the clinical workflow.

The floor should integrate correctly with the modular walls and wall-to-floor detailing.
The engineering team should also consider equipment movement and the cleaning procedures used by the hospital.
18. Plan Workflow and Zoning
The operating theatre is part of a larger surgical department, so the surrounding workflow also matters.
The overall design may consider:
- Patient entry
- Staff entry
- Scrub area
- Preparation areas
- Sterile storage
- Equipment storage
- Instrument movement
- Waste movement
- Recovery or transfer
Altus Airflow’s modular OT design information describes workflow planning and zoning as part of its OT design approach.
The actual zoning should be established according to the hospital’s architectural layout and clinical workflow.
19. Consider Cleaning and Infection-Control Procedures
The OT should be designed to support the hospital’s established cleaning and infection-prevention practices.
This can involve appropriate:
- Wall finishes
- Ceiling surfaces
- Flooring
- Sealed joints
- Corners
- Doors
- Equipment positioning
- Air-management systems
A manufacturer should avoid presenting any single product as a guarantee against infection. OT safety depends on the interaction between environmental systems, clinical practices, cleaning, equipment, and hospital protocols.
20. Design for Maintenance
Maintenance should be considered before construction begins.
The engineering team should provide practical access to:
- AHU components
- HEPA filters
- Control panels
- Electrical systems
