Most NHS Trusts and private hospitals have an on-going commitment to the improvement of their medical provision and facilities.
To support this, there is often a need to undertake an upgrade of the theatre ventilation plant with particular emphasis on legislative and compliance with HTMs to support the nature of the operations intended to be carried out.
Laminar flow or ultraclean ventilation is used in modern operating theatres to reduce the number of infective organisms present in the air that can lead to post-operative wound infection.
A continuous flow of highly filtered ‘bacteria-free’ air is re-circulated under positive pressure into the operating field and air bone contaminants generated during surgery are removed from the site.
While conventional or plenum type ventilation in operating theatres maintains approximately 20 air changes per hour, ultra clean operating theatres may operate
at upwards of 300 to 500 air changes per hour in the critical zone.
Following feasibility assessments by NIFES, we have provided design consultancy for a number of ultra-clean ventilation systems for theatres for a number of hospitals.
NIFES act as lead consultant in all aspects of the design and execution of works and prepare the specification making allowances for compliance with all of the relevant statutory and mandatory requirements, but in particular matching the requirements of the theatre and the guidelines as set by both current legislation and good practice.
