NABH Guidelines for OT
As per NABH (National Accreditation Board for Hospitals and Healthcare Providers in India), below are the Air-conditioning requirements for Operation Theatres. NABH doesn't mandate the OTs to be modular, as long as they satisfy the following requirements. It is up to the Healthcare Organization to go with either a modular or a normal OT.
As per NABH, the OTs are classified as, Type A and Type B.
- Type A (Super-Speciality OT): For carrying out surgical procedures related to Cardiothoracic surgery, Neurosurgery, Orthopaedic surgery (Joint & Hip replacements), Vascular Surgery, Tumour removal, Transplant surgeries (heart, liver, kidney), etc.
- Type B (General OT): Primarily used for carrying out less critical surgical procedures such as day-care procedures, IVF, gynaecology, ophthalmology and other general surgeries.
Air-Conditioning Requirements for OT
| Parameter | Super-specialty OT | General OT |
|---|---|---|
| Temperature | 21±3°C. 18±2°C for joint replacements. | 21±3°C |
| Humidity (%) | 20-60% | 20-60% |
| Pressurization | The OT shall always be maintained at least 7.5 Pascals more than the adjacent space. | |
| Air Changes/Hour | > 20 | > 20 |
| Fresh Air | ~20% | ~20% |
| Air Velocity | Unidirectional airflow on the OT table. The air face velocity of 25-35 FPM. | |
| Air Supply | The air is supplied to OT through terminal HEPA (High-Efficiency Particulate Air) Filters mounted on the ceiling. | |
| Filtration | The AHU shall have G-4 Prefilters (10 µm), F-7 Fine Filters (5 µm). The terminally mounted LAF / H14 HEPA Filters filter out particles of size more than 0.3 µm with 99.997% Efficiency. | |
Construction of OT
Wall & Ceiling Systems
We offer various options for wall and ceiling cladding to prevent generation of airborne particles. Options include:
- Stainless-Steel PUFF panels
- Pre-painted Stainless-Steel panels
- GI panels with anti-microbial paint
- Antibacterial PU paint on brick wall
- Antibacterial PVC panels
- HPL PUFF panelling
- Glass, Corian and Radio-opaque lining on walls
Flooring
Flooring is a very important part of an OT. The flooring shall be selected to have higher durability and sealed airtight. Key considerations include:
- Electrostatic discharges (ESD): To protect equipment, an antistatic dissipative floor is chosen.
- Durability: High durability and load-bearing capacity to withstand heavy traffic.
- Low VOC: Epoxy and polyurethane resins are used as they are inert and low in Volatile Organic Compounds.
- Antimicrobial property: Flooring can have antimicrobial additives to target bacteria.
